Thanks for the excellent tutorial on testing the VSV! I am running a manual 1,33 L 2010 Corolla (1NR-FE) here in Finland. It whistles under cold starts in the winter, particularly when upshifting between gear 2, 3 and 4 (similarly as in the end of your video, noticed while driving in the cabin of the car). I just noticed that it has also started to burn oil (about 1/2 L in 500 km; 10 L per year?!). There was some black soot in the tailpipe when I checked so it is not a leak. I had suspicions about the EGR system earlier but the local mechanic suspected the whistle was coming from the bearings in the belt tensioner. I am currently running it with the original Toyota full synthetic 0W-20. Having added a half-liter yesterday the oil cap was difficult to open, indicating there is a vaccuum (under-pressure). Any tips on where to start? Could it be the VSV valve?
Burning oil is often the result of worn out parts. For example, worn valve seals and/or piston rings could lead to your car burning oil. Both valve seals and piston rings work to keep engine oil out of the combustion chamber. All of the above applies if you do not have external leaks in the engine lubrication system from eg engine oil filter, oil plug washer, oil pan gasket, etc. Can a PCV valve burn oil? If your engine is burning oil, hope that it's due to a bad PCV valve. The PCV valve is designed to allow air to escape the crankcase when the pressure inside grows too high -- but when it malfunctions, it can begin sucking oil into the engine and burning it there instead.
@@YiannisPagonis Thanks for the reply! I hope it is only the PCV valve as well. I cleaned it and also the VSV. I also added some Oil Smoke Stop additive to the engine oil. The car still whistles but at least it runs. Let's see if it continues burning...
@@YiannisPagonis I didn't. I will have to look into those if the burning of the oil doesn't stop. Do you think those might have something to do with the whistling?
Yes my friend the vacuum switching valve (VSV) is so important for the proper operation of the engine because controls the vacuum supply to the actuator is normally closed and passes vacuum to the actuator when it is energized by the ECU. By energizing the VSV vacuum is passed to the actuator, closing the air control valve. This effectively lengthens the intake manifold run.
Hi! Can you make a video about removing the steering wheel and fixing the strange noise (clicking) that comes from it’s mechanism. Would really appreciate that. You’ve done a great work!
Hi, I have a lexus ls430 2005 model. I did a ac compressor replacement. For which I had to remove the air filter, radiator and fan. When I connected it back on, my car is have stalling on idle and also when accelerating, when pressed full pedal it takes 4 to 5 seconds to hit the highest rpm. When I am connecting the computer it is showing cylinder 3 and 5 misfire, I also replaced the coil and spark plugs with the other cylinders still it shows 3 and 5. Can you help me out here please
When replacing car AC compressor what else should be replaced? For the compressor that is seized, you will at the very least need to replace the compressor assembly and clutch, receiver drier, expansion valve, and flush out the system. I recommend having a mechanic diagnose your vehicle to see if any other components need replaced in order to fix your air conditioner. Why does my AC cause my car to stall? A fault in the IAC such as build up, can cause poor idling or stalling of the engine. If not working properly, the engine may not cope with the loads produced by various systems in the car. More specifically, it may be too low to run the A/C and hence it stalls when turned on. What will a bad IAC cause? When the idle air control valve fails, it inhibits the flow of air through the engine. When the car can't receive air, it leads to engine stalling. The severity of this symptom can range from occasional stalling at first, to stalling immediately after ignition.
today i changed my air filter cover so i had to to disconnect the same sesnor in the vedio, after i connected everything back my car would start for 5 Sec with a very poor rpm then its shut down.. i took this sesnor out and connected it to a battery its closed both way no air follow at all! my car is LS430 2001, do i change the vacuum sensor or i should check the connecting that coming out from the car maybe a one is loosing?
So my friend when you install the filter cover and the engine air filter itself did they fit together correctly? Did you secure the 2 air filter clamps? Also, the new filter cover you installed, are there any cracks, holes, or any such damage? The rest of the parts were placed correctly?
Great video, im having an issue where my Toyota Corolla starts up then shuts off immediately. I replaced spark plugs, coils, fuel injectors and verified that the fuel pump is working properly. I cleaned my MAF sensor, it might need replacing. This is the last part that I feel I need to check, praying it has not failed.
@@YiannisPagonis Yes, I narrowed it down to the throttle body. I had a friend use his snap on OBD scanner and it threw a P2103 code. I'm ordering a new one soon.
@@harlemsfinest05 What is the code P2103 on a Toyota Corolla? My brief, very brief, research says that this code (P2103) is set when the ECU doesn't see the correct current at the throttle body. Notice it says “current” and not voltage. The ECU monitors current
No it is not normal my friend. It can be a dangerous problem, but with the right knowledge, you can identify, fix, and prevent an EVAP leak. An EVAP leak, or evaporative emissions control system leak, occurs when fuel vapors escape from the car's fuel tank or any other part of the system that controls them. What are the symptoms of a faulty purge valve? If the Purge Valve is stuck open or closed, it can cause the engine to run poorly or not start at all. A defective Purge Valve can also manifest itself through symptoms like reduced engine power, sluggish acceleration, and even engine stalling.
@@YiannisPagonis i just ordered a replacement, verified today that it was broken. Im waiting it to arrived then will install it. Hope it's working. Thanks
How do I find the information regarding expected resistance at different ambient temperatures? And how much affect can this have if being outside expected resistance is the only failure?
The resistance R of an object also varies with temperature: R=R0(1+αΔT) R = R 0 ( 1 + α Δ T ) , where R0 is the original resistance, and R is the resistance after the temperature change. The resistance of all materials changes as their temperature changes. If the temperature is lowered, resistance (typically) declines. In fact, if cooled sufficiently, the material becomes a "superconductor" with no significant resistance. Increasing the temperature (typically) increases resistance.

Hi. What happens if this part is broken? My car vibrates at idle when engine is fully warm. And there is a ticking sound begins. Looked everything for problem with repairmen but we couldn't find anything. This part is suspicious for me now. I've losen the bottom hose like in this video but it don't vacuums like your car's.

@@yusufaras01 My friend, use Google translate for better translation results (as I do too). Now an idle problem could be all sorts of things, particularly if you have a lot of miles on the car, such as perhaps you need to replace the engine air filter, clean the throttle body, or maybe patch a vacuum leak in the air line with a piece of duct tape, etc, however usually these are cheap fixes
Hi friend, thanks for video.May this part cause p0660 fail code ? I observed that when i touch this part i hear sound on intake manifold and i saw failure lamps on dashboard.I tested this part.Everything is ok but I measured 3 ohms on multimeter about 25 °C.
CODE P0660: Intake manifold tuning valve control circuit/open bank 1 When your engine control module registers an electrical fault or other open electrical issue on bank one, it triggers error code P0660. You’re probably wondering, how do I fix trouble code P0660? Here are some symptoms of this trouble code, common causes and steps to take to restore your vehicle. WHAT IS AN INTAKE MANIFOLD TUNING VALVE? This manifold is used to change the air intake of your vehicle and redirect it to a separate set of intake runners. It also regulates the pressure between intake plenums. This simple valve is commonly made of plastic and is subject to wear and damage, particularly from extreme temperatures. A P0660 trouble code can be the result of either an electrical or mechanical issue. Look for these symptoms and determine the cause before you look for a repair solution. SYMPTOMS OF ERROR CODE P0660 So, what does the code P0660 mean? While this error code could be the result of a damaged sensor, it could also be the first sign of a serious issue. It’s important to treat this error code seriously to avoid any additional damage in the future. A damaged intake manifold tuning valve could cause your engine to perform poorly altogether. From cold start issues and startup misfires to decreased fuel economy and clicking sounds in your engine compartment, there are a range of symptoms that could be caused by trouble code P0660. Some are minor inconveniences, while others can reduce the efficiency of your vehicle or make it difficult to start your vehicle reliably. When working properly, your intake manifold tuning valve promotes an optimal balance of air pressure and airflow in your engine. An improper valve could allow too much or too little air and pressure to reduce the efficiency of your engine or cause damage to other areas of your engine. COMMON CAUSES OF P0660 Once you’ve determined that your engine issues are the result of error code P0660, here are some common causes to inspect. Whether you have a single issue or a series of faults, look for solutions for one or more of these issues: Damaged intake manifold tuning valve Cracked or stuck valve parts Poor performance due to extremely cold weather Loose connectors, frayed wiring or corroded electrical components Issues with your engine control module Valve contamination Thankfully, each of these causes can be found and solved. Find your intake manifold tuning valve and begin to inspect it and related components. Use voltage testers to go over the electrical connections and ensure proper electricity to all your sensors and essential parts. Once you’ve discovered the area that needs repairs, you can determine the best solution. FINDING A SOLUTION For a trouble code P0660 issue, you’ll typically need to replace your intake manifold tuning valve or other component. The most common solution is replacing a part that has cracked due to exposure to the extreme cold or melted due to the extreme heat of your engine. If nothing is obviously broken after a visual inspection, check your valve. Some OBD-II scanners allow you to activate your valve. If so, look for any sticking points or areas where it isn’t operating with its full range of motion. Temperature-related damage may be the cause of this OBD-II scanner error code P0660 problem, but it could be a symptom of other damage. Check to see if other error codes are active and inspect other areas of your engine for possible damage. After you replace your intake manifold tuning valve, parts or electrical wiring, be sure to test your vehicle and see whether the error code returns. If it does, you’ll need to go over common causes again or check your engine control module.
@@rhodellabasan1441 Happy new year my friend to you and your family. So Don't open the Valve. Clean the Valve: Spray the valve with carb cleaner or throttle body cleaner (or with electronic cleaner). Use your small brush to clean off any debris or buildup. Be careful not to damage any parts of the valve while cleaning.

What Does The Vacuum Switch Valve Do? The vacuum switching valve (VSV) regulates the vacuum supply to the actuator. It is usually closed and only opens when the electronic control unit energizes it. By turning on the VSV and shutting the air control valve, the vacuum is directed to the actuator. This essentially lengthens the air intake manifold. In contrast, de-energizing the VSV blocks the vacuum to the actuator, draining the trapped vacuum off the diaphragm. The VSV determines when the fuel vapor is allowed to escape from the charcoal canister and go into the vacuum. When the valve works properly, it will create an audible cracking sound when it opens and shuts. These valves can be controlled by hand, pneumatically, or electrically. Also, a coolant VSV acts as the heater control valve for many automobiles. It is a basic electrical switch that is opened and closed by a diaphragm vacuum. This switch, when triggered, allows antifreeze into the inside of the heater core. This makes the heater work and reduces air temperature. Since the coolant vacuum switch effectively works as a heater control valve, it can disable the heater core if it malfunctions or has any faults. In the long run, the worst-case scenario is that driving with a vacuum leak and elevated temperatures caused by operating a lean air-fuel ratio might lead to broken engines. That said, the vacuum leaks might stem from a bad valve cover gasket, so check every related part carefully. What Are Bad Vacuum Switching Valve Symptoms? There are some symptoms inside the VSV valve and heater core, such as the heater releasing warm air or not blowing any warm air at all and coolant leaks. Beside, other signs of a faulty EGR valve you can observe with your eyes are: Your car has a rough idle. The car has increased fuel consumption and decreased fuel efficiency. You can smell fuel. The engine management light stays on. There are more vehicle emissions. There are engine noises when driving, like knocking or tapping. Low engine speeds A faulty vacuum switch valve can result in many mechanical problems for your car. Thus, knowing the symptoms of a failing VSV could help you notice the issues soon and take actions to deal with them.
@@YiannisPagonis and a last little thing, in my channel i shoot my car's idle sound while vibrating. it's working with tiktiktik sound and vibrates while engine gets warm. before there wasn't any issue... really annoying and couldn't find any solution.
@@yusufaras9066 My friend I watched your video and I understood that you should not worry at all about this sound (tik tik tik) because it is a normal sound. It comes from the fuel injectors as they spray fuel into the engine cylinders. This sound is louder when the engine has warmed up. Same thing with my engine (as with all Corolla engines).

11 Causes Of RPM Going Up And Down There are a few reasons why your car’s RPM might be going up and down at idle. 1. Worn Out Spark Plugs One common reason for RPM fluctuations is worn-out spark plugs. When the plugs are in bad condition, they can’t produce a strong spark, making it difficult for the engine to run smoothly. As a result, the RPMs may go up and down as the car tries to compensate. If your spark plugs are worn out, they should be replaced as soon as possible. 2. Damaged Ignition Wires Another potential cause of RPM fluctuations is damage to the ignition wires. If the wires are broken or frayed, it can create resistance in the electrical current and disrupt the engine idle speed. This can cause the RPMs to rise and fall unpredictably. 3. Vacuum Leaks When there’s a leak in the vacuum line, it causes a loss of engine vacuum. It makes it difficult for the engine to function properly and can cause the RPMs to fluctuate. You can check for a vacuum leak by spraying a soapy water solution around the suspected area. If you see bubbles, then you’ve found your vacuum leak. Once you’ve located the vacuum leak, there are a few things you can do to fix it: If the leak is caused by a crack or a hole in the hose, you can replace the hose. If the leak is caused by a loose fitting, you can tighten the fitting. If the leak is caused by a torn gasket, you can replace the gasket. If the leak is caused by a hole in the engine, you may need to have the engine repaired or replaced. 4. Carburetor Problems A carburetor that’s not properly working can also cause the RPMs to fluctuate. If the carburetor is dirty or clogged, it won’t provide the engine with the right amount of fuel. It can lead to a rough idle and cause the RPMs to fluctuate. 5. Clogged Fuel Injector A clogged fuel injector can also cause the engine to run erratically. When the injector is clogged, it can’t deliver the right amount of fuel to the engine. It can lead to surging and stalling and cause the RPMs to go up and down. There are a few things that you can do to try and unclog your fuel injector. One thing you can try is to use a fuel injector cleaner. This will help to clean the gunk and debris that has built up in the injector. You can also try using a high-pressure air hose to blast the clog out of the injector. 6. Dirty Air Filter A dirty air filter can also cause the engine to run unevenly. When there is a clogged fuel filter with dirt and dust, it can’t allow enough air to get into the engine. It can cause the RPMs to increase or decrease unexpectedly. Be sure to change your air filter regularly to avoid this issue. 7. Bad Idle Air Control Valve A bad idle control valve can also lead to fluctuations in the RPMs. If you’re noticing that your RPMs are constantly going up and down, even when you’re not accelerating, it’s likely that you have a bad idle air control valve. The best way to determine if your idle air control valve is the issue is to check engine light. If it’s on, there’s a good chance that the idle air control valve is the problem. 8. Incorrect Valve Timing If the valves are not timed correctly, the engine can be difficult to run. This can lead to the RPMs going up and down as the car compensates. This is because the incorrect valve timing will affect the air/fuel mixture and the engine’s ability to create power. At a minimum, the valve timing should be checked and adjusted if needed. In some cases, a new valve timing belt may be needed in order to correct the issue. 9. Faulty Throttle Pedal Position Sensor A faulty throttle pedal position sensor can also cause the RPMs to go up and down. This sensor is responsible for sending information to the car’s computer about how far you have depressed the pedal. If it is malfunctioning, it can cause the engine to rev up and down erratically. There are a few things you can do to troubleshoot a faulty throttle pedal position sensor. First, check the wiring and connectors to make sure they are all connected and in good condition. Next, check the sensor itself for any damage or debris that may be interfering with its operation. 10. Transmission Issues If the transmission is not working correctly, it can cause the engine to struggle. This can lead to the RPMs spiking or dropping unexpectedly. First, make sure that your transmission fluid is at the correct level. If it is low, adding more fluid may help to fix the problem. You can also try changing the transmission fluid altogether, as this may help to get rid of any issues that you are having. If neither of those things seems to help, it is possible that there is an issue with your transmission itself. In this case, you will need to take it to a mechanic. 11. Problem With The Combustion Process If something is wrong with the combustion process, it can cause the RPM to go up and down. One possible problem is a misfire. This happens when the air/fuel mixture doesn’t ignite properly, and it can cause the RPM to spike. Another problem is detonat
You can try to clean it without opening it. If that doesn't work and you have good technical skills, or you want to do a deep cleaning, you could open the purge solenoid valve.
First of all my car has no oil / petrol leaks which is very important for the good appearance and operation of the engine. Now to your question about how to keep my engine in this condition: I just clean it regularly with a dashboard polish and plastic parts. That's all! You can do this too!
Hello, thanks for the video, very well done. I ask you, what is the name of that valve? And if it is defective, it can cause an unstable idle and go up and down from 1000 to 2000 rpm when the car is running? Thanks and regards

@@enriqueatala2567 My friend, I think I have found the solution to your problem: the problem is in the throttle body and specifically in the idle air control valve. You may have a dirty or failing idle air control valve causing your engine idle to fluctuate.

It is inside a plastic casing which is not visible, that is, it is in a hidden place. What is the EVAP system on a Toyota Corolla? Evaporative Emission Control (EVAP) System - Code P0441 Diagnostic The EVAP system manages gasoline vapor evaporation from the gas tank and fuel systems. It consists of several parts but works relatively simply. Vapors from the gasoline tank, as the vehicle sits, idles, ambient temperatures change, etc. can begin to exert pressure on the fuel tank. How does Toyota EVAP system work? Fuel vapors from the fuel tank are captured in the charcoal canister and extracted when the engine is running. If vapor pressure increases in the fuel tank or during refueling events, excess pressure is released from the normally open vent valve via the canister air filter. How to fix P0441 To repair error code P0441, you'll need to first diagnose the code and determine exactly what the issue is. Replacing the gas cap and purge valve are two of the most common fixes for this error code. However, there could be other issues that trigger this code, like disconnected or damaged wires within your EVAP system. What are the components of car EVAP system? EVAP systems have been required on gasoline powered vehicles since the 1970s. A typical system consists of the fuel tank, an EVAP vapor storage canister full of charcoal, valves, hoses and a sealed fuel tank gas cap. The EVAP system is designed to stop fuel system fumes from leaking directly into the atmosphere. يا صديقي، هذه الوظيفة (إذا كانت من طراز كورولا من الجيل العاشر مثل طرازي) فهي عملية صعبة للغاية وشاقة وتستغرق وقتًا طويلاً ولا يستطيع سوى عدد قليل جدًا من الأشخاص القيام بها (الإزالة والاستبدال). وهي داخل غلاف بلاستيكي غير ظاهر، أي أنها في مكان مخفي. ما هو نظام EVAP في تويوتا كورولا؟ نظام التحكم في الانبعاثات التبخرية (EVAP) - الكود P0441 التشخيصي يقوم نظام EVAP بإدارة تبخر بخار البنزين من خزان الغاز وأنظمة الوقود. يتكون من عدة أجزاء ولكنه يعمل بشكل بسيط نسبيًا. يمكن للأبخرة المنبعثة من خزان البنزين أثناء وقوف السيارة في وضع الخمول وتغير درجات الحرارة المحيطة وما إلى ذلك أن تبدأ في ممارسة الضغط على خزان الوقود. كيف يعمل نظام تويوتا EVAP؟ يتم التقاط أبخرة الوقود من خزان الوقود في علبة الفحم ويتم استخراجها عند تشغيل المحرك. إذا زاد ضغط البخار في خزان الوقود أو أثناء أحداث التزود بالوقود، فسيتم تحرير الضغط الزائد من صمام التهوية المفتوح عادة عبر مرشح الهواء العلبة. كيفية إصلاح P0441 لإصلاح رمز الخطأ P0441، ستحتاج أولاً إلى تشخيص الرمز وتحديد المشكلة بالضبط. يعد استبدال غطاء الغاز وصمام التطهير من أكثر الإصلاحات شيوعًا لرمز الخطأ هذا. ومع ذلك، قد تكون هناك مشكلات أخرى تؤدي إلى ظهور هذا الرمز، مثل الأسلاك المنفصلة أو التالفة داخل نظام EVAP الخاص بك. ما هي مكونات نظام EVAP للسيارة؟ أصبحت أنظمة EVAP مطلوبة في المركبات التي تعمل بالبنزين منذ السبعينيات. يتكون النظام النموذجي من خزان الوقود، وعلبة تخزين بخار EVAP المملوءة بالفحم، والصمامات، والخراطيم، وغطاء غاز محكم الغلق لخزان الوقود. تم تصميم نظام EVAP لمنع أبخرة نظام الوقود من التسرب مباشرة إلى الغلاف الجوي.

Thanks for the excellent tutorial on testing the VSV! I am running a manual 1,33 L 2010 Corolla (1NR-FE) here in Finland. It whistles under cold starts in the winter, particularly when upshifting between gear 2, 3 and 4 (similarly as in the end of your video, noticed while driving in the cabin of the car). I just noticed that it has also started to burn oil (about 1/2 L in 500 km; 10 L per year?!). There was some black soot in the tailpipe when I checked so it is not a leak. I had suspicions about the EGR system earlier but the local mechanic suspected the whistle was coming from the bearings in the belt tensioner. I am currently running it with the original Toyota full synthetic 0W-20. Having added a half-liter yesterday the oil cap was difficult to open, indicating there is a vaccuum (under-pressure). Any tips on where to start? Could it be the VSV valve?
Burning oil is often the result of worn out parts. For example, worn valve seals and/or piston rings could lead to your car burning oil. Both valve seals and piston rings work to keep engine oil out of the combustion chamber. All of the above applies if you do not have external leaks in the engine lubrication system from eg engine oil filter, oil plug washer, oil pan gasket, etc.
Can a PCV valve burn oil?
If your engine is burning oil, hope that it's due to a bad PCV valve. The PCV valve is designed to allow air to escape the crankcase when the pressure inside grows too high -- but when it malfunctions, it can begin sucking oil into the engine and burning it there instead.
@@YiannisPagonis Thanks for the reply! I hope it is only the PCV valve as well. I cleaned it and also the VSV. I also added some Oil Smoke Stop additive to the engine oil. The car still whistles but at least it runs. Let's see if it continues burning...
@@hapet09 Henrik Petaisto: Did you Clean and Check Camshaft Timing Oil Control Valve and its Filter;
@@YiannisPagonis I didn't. I will have to look into those if the burning of the oil doesn't stop. Do you think those might have something to do with the whistling?

Hi, were to locate the valve on a Toyota avensis 1.8 benzina valvematic?
I’ll test it in my car . Thanks a lot 🌹
Yes my friend try it. You can do it too. It is not difficult. I am waiting for your news about this.
Sir. Is it normal to have knocking sounds on the vsv. I have change my vsv but same sounds comes up after a run.
Can tell me direction for tow hose going??
Great video very helpful thank you
You are welcome my friend
Hi, I have a lexus ls430 2005 model. I did a ac compressor replacement. For which I had to remove the air filter, radiator and fan. When I connected it back on, my car is have stalling on idle and also when accelerating, when pressed full pedal it takes 4 to 5 seconds to hit the highest rpm. When I am connecting the computer it is showing cylinder 3 and 5 misfire, I also replaced the coil and spark plugs with the other cylinders still it shows 3 and 5.
Can you help me out here please
When replacing car AC compressor what else should be replaced?
For the compressor that is seized, you will at the very least need to replace the compressor assembly and clutch, receiver drier, expansion valve, and flush out the system. I recommend having a mechanic diagnose your vehicle to see if any other components need replaced in order to fix your air conditioner.
Why does my AC cause my car to stall?
A fault in the IAC such as build up, can cause poor idling or stalling of the engine. If not working properly, the engine may not cope with the loads produced by various systems in the car. More specifically, it may be too low to run the A/C and hence it stalls when turned on.
What will a bad IAC cause?
When the idle air control valve fails, it inhibits the flow of air through the engine. When the car can't receive air, it leads to engine stalling. The severity of this symptom can range from occasional stalling at first, to stalling immediately after ignition.
today i changed my air filter cover so i had to to disconnect the same sesnor in the vedio, after i connected everything back my car would start for 5 Sec with a very poor rpm then its shut down.. i took this sesnor out and connected it to a battery its closed both way no air follow at all! my car is LS430 2001, do i change the vacuum sensor or i should check the connecting that coming out from the car maybe a one is loosing?
So my friend when you install the filter cover and the engine air filter itself did they fit together correctly? Did you secure the 2 air filter clamps? Also, the new filter cover you installed, are there any cracks, holes, or any such damage? The rest of the parts were placed correctly?
Great video, im having an issue where my Toyota Corolla starts up then shuts off immediately. I replaced spark plugs, coils, fuel injectors and verified that the fuel pump is working properly. I cleaned my MAF sensor, it might need replacing. This is the last part that I feel I need to check, praying it has not failed.
Well you did all this but what was the result? Is your car working normally without problems?
@@YiannisPagonis Yes, I narrowed it down to the throttle body. I had a friend use his snap on OBD scanner and it threw a P2103 code. I'm ordering a new one soon.

@@harlemsfinest05 What is the code P2103 on a Toyota Corolla?
My brief, very brief, research says that this code (P2103) is set when the ECU doesn't see the correct current at the throttle body. Notice it says “current” and not voltage. The ECU monitors current

Hi, is it normal to have gasoline leak in the vapor hose going to the purge valve? Does it mean my valve is broken?
No it is not normal my friend. It can be a dangerous problem, but with the right knowledge, you can identify, fix, and prevent an EVAP leak. An EVAP leak, or evaporative emissions control system leak, occurs when fuel vapors escape from the car's fuel tank or any other part of the system that controls them.
What are the symptoms of a faulty purge valve?
If the Purge Valve is stuck open or closed, it can cause the engine to run poorly or not start at all. A defective Purge Valve can also manifest itself through symptoms like reduced engine power, sluggish acceleration, and even engine stalling.
@@YiannisPagonis i just ordered a replacement, verified today that it was broken. Im waiting it to arrived then will install it. Hope it's working. Thanks

How do I find the information regarding expected resistance at different ambient temperatures? And how much affect can this have if being outside expected resistance is the only failure?
The resistance R of an object also varies with temperature: R=R0(1+αΔT) R = R 0 ( 1 + α Δ T ) , where R0 is the original resistance, and R is the resistance after the temperature change. The resistance of all materials changes as their temperature changes. If the temperature is lowered, resistance (typically) declines. In fact, if cooled sufficiently, the material becomes a "superconductor" with no significant resistance. Increasing the temperature (typically) increases resistance.
@@YiannisPagonis ok, so science, not something built into the part to be an even bigger difference, thanx 😁
@@maggiewilder8856 No, it is the ambient temperature that changes the resistance values 😮😮

What is the function of this piece?
The vacuum switching valve (VSV) which controls the vacuum supply to the actuator is normally closed and passes vacuum to the actuator when it is energized by the ECU. By energizing the VSV vacuum is passed to the actuator, closing the air control valve. This effectively lengthens the intake manifold run.

Hi bro. I have toyota camry acv40. VSV vale spec it same video ? Thank you bro. P
Hi friend, thanks for video.May this part cause p0660 fail code ? I observed that when i touch this part i hear sound on intake manifold and i saw failure lamps on dashboard.I tested this part.Everything is ok but I measured 3 ohms on multimeter about 25 °C.
CODE P0660: Intake manifold tuning valve control circuit/open bank 1
When your engine control module registers an electrical fault or other open electrical issue on bank one, it triggers error code P0660. You’re probably wondering, how do I fix trouble code P0660? Here are some symptoms of this trouble code, common causes and steps to take to restore your vehicle.
WHAT IS AN INTAKE MANIFOLD TUNING VALVE?
This manifold is used to change the air intake of your vehicle and redirect it to a separate set of intake runners. It also regulates the pressure between intake plenums. This simple valve is commonly made of plastic and is subject to wear and damage, particularly from extreme temperatures.
A P0660 trouble code can be the result of either an electrical or mechanical issue. Look for these symptoms and determine the cause before you look for a repair solution.
SYMPTOMS OF ERROR CODE P0660
So, what does the code P0660 mean? While this error code could be the result of a damaged sensor, it could also be the first sign of a serious issue. It’s important to treat this error code seriously to avoid any additional damage in the future.
A damaged intake manifold tuning valve could cause your engine to perform poorly altogether. From cold start issues and startup misfires to decreased fuel economy and clicking sounds in your engine compartment, there are a range of symptoms that could be caused by trouble code P0660. Some are minor inconveniences, while others can reduce the efficiency of your vehicle or make it difficult to start your vehicle reliably.
When working properly, your intake manifold tuning valve promotes an optimal balance of air pressure and airflow in your engine. An improper valve could allow too much or too little air and pressure to reduce the efficiency of your engine or cause damage to other areas of your engine.
COMMON CAUSES OF P0660
Once you’ve determined that your engine issues are the result of error code P0660, here are some common causes to inspect. Whether you have a single issue or a series of faults, look for solutions for one or more of these issues:
Damaged intake manifold tuning valve
Cracked or stuck valve parts
Poor performance due to extremely cold weather
Loose connectors, frayed wiring or corroded electrical components
Issues with your engine control module
Valve contamination
Thankfully, each of these causes can be found and solved. Find your intake manifold tuning valve and begin to inspect it and related components. Use voltage testers to go over the electrical connections and ensure proper electricity to all your sensors and essential parts. Once you’ve discovered the area that needs repairs, you can determine the best solution.
FINDING A SOLUTION
For a trouble code P0660 issue, you’ll typically need to replace your intake manifold tuning valve or other component. The most common solution is replacing a part that has cracked due to exposure to the extreme cold or melted due to the extreme heat of your engine.
If nothing is obviously broken after a visual inspection, check your valve. Some OBD-II scanners allow you to activate your valve. If so, look for any sticking points or areas where it isn’t operating with its full range of motion.
Temperature-related damage may be the cause of this OBD-II scanner error code P0660 problem, but it could be a symptom of other damage. Check to see if other error codes are active and inspect other areas of your engine for possible damage. After you replace your intake manifold tuning valve, parts or electrical wiring, be sure to test your vehicle and see whether the error code returns. If it does, you’ll need to go over common causes again or check your engine control module.

What kind of problem occurs if that piece is broken?
What Does The Vacuum Switch Valve Do?
The vacuum switching valve (VSV) regulates the vacuum supply to the actuator. It is usually closed and only opens when the electronic control unit energizes it. By turning on the VSV and shutting the air control valve, the vacuum is directed to the actuator. This essentially lengthens the air intake manifold. In contrast, de-energizing the VSV blocks the vacuum to the actuator, draining the trapped vacuum off the diaphragm. The VSV determines when the fuel vapor is allowed to escape from the charcoal canister and go into the vacuum. When the valve works properly, it will create an audible cracking sound when it opens and shuts. These valves can be controlled by hand, pneumatically, or electrically. Also, a coolant VSV acts as the heater control valve for many automobiles. It is a basic electrical switch that is opened and closed by a diaphragm vacuum. This switch, when triggered, allows antifreeze into the inside of the heater core. This makes the heater work and reduces air temperature. Since the coolant vacuum switch effectively works as a heater control valve, it can disable the heater core if it malfunctions or has any faults. In the long run, the worst-case scenario is that driving with a vacuum leak and elevated temperatures caused by operating a lean air-fuel ratio might lead to broken engines. That said, the vacuum leaks might stem from a bad valve cover gasket, so check every related part carefully.
What Are Bad Vacuum Switching Valve Symptoms?
There are some symptoms inside the VSV valve and heater core, such as the heater releasing warm air or not blowing any warm air at all and coolant leaks. Beside, other signs of a faulty EGR valve you can observe with your eyes are:
Your car has a rough idle.
The car has increased fuel consumption and decreased fuel efficiency.
You can smell fuel.
The engine management light stays on.
There are more vehicle emissions.
There are engine noises when driving, like knocking or tapping.
Low engine speeds
A faulty vacuum switch valve can result in many mechanical problems for your car. Thus, knowing the symptoms of a failing VSV could help you notice the issues soon and take actions to deal with them.

Sir, when i pull off the hose (one facing down) my engine automatically turned off. What does that mean?
On your video, when you pull the hose, i think the engine is running.
Hi good video can this part cause rpm to go.up and down if not working thanks
11 Causes Of RPM Going Up And Down
There are a few reasons why your car’s RPM might be going up and down at idle.
1. Worn Out Spark Plugs
One common reason for RPM fluctuations is worn-out spark plugs. When the plugs are in bad condition, they can’t produce a strong spark, making it difficult for the engine to run smoothly. As a result, the RPMs may go up and down as the car tries to compensate. If your spark plugs are worn out, they should be replaced as soon as possible.
2. Damaged Ignition Wires
Another potential cause of RPM fluctuations is damage to the ignition wires. If the wires are broken or frayed, it can create resistance in the electrical current and disrupt the engine idle speed. This can cause the RPMs to rise and fall unpredictably.
3. Vacuum Leaks
When there’s a leak in the vacuum line, it causes a loss of engine vacuum. It makes it difficult for the engine to function properly and can cause the RPMs to fluctuate. You can check for a vacuum leak by spraying a soapy water solution around the suspected area. If you see bubbles, then you’ve found your vacuum leak. Once you’ve located the vacuum leak, there are a few things you can do to fix it:
If the leak is caused by a crack or a hole in the hose, you can replace the hose.
If the leak is caused by a loose fitting, you can tighten the fitting.
If the leak is caused by a torn gasket, you can replace the gasket.
If the leak is caused by a hole in the engine, you may need to have the engine repaired or replaced.
4. Carburetor Problems
A carburetor that’s not properly working can also cause the RPMs to fluctuate. If the carburetor is dirty or clogged, it won’t provide the engine with the right amount of fuel. It can lead to a rough idle and cause the RPMs to fluctuate.
5. Clogged Fuel Injector
A clogged fuel injector can also cause the engine to run erratically. When the injector is clogged, it can’t deliver the right amount of fuel to the engine. It can lead to surging and stalling and cause the RPMs to go up and down. There are a few things that you can do to try and unclog your fuel injector. One thing you can try is to use a fuel injector cleaner. This will help to clean the gunk and debris that has built up in the injector. You can also try using a high-pressure air hose to blast the clog out of the injector.
6. Dirty Air Filter
A dirty air filter can also cause the engine to run unevenly. When there is a clogged fuel filter with dirt and dust, it can’t allow enough air to get into the engine. It can cause the RPMs to increase or decrease unexpectedly. Be sure to change your air filter regularly to avoid this issue.
7. Bad Idle Air Control Valve
A bad idle control valve can also lead to fluctuations in the RPMs. If you’re noticing that your RPMs are constantly going up and down, even when you’re not accelerating, it’s likely that you have a bad idle air control valve. The best way to determine if your idle air control valve is the issue is to check engine light. If it’s on, there’s a good chance that the idle air control valve is the problem.
8. Incorrect Valve Timing
If the valves are not timed correctly, the engine can be difficult to run. This can lead to the RPMs going up and down as the car compensates. This is because the incorrect valve timing will affect the air/fuel mixture and the engine’s ability to create power. At a minimum, the valve timing should be checked and adjusted if needed. In some cases, a new valve timing belt may be needed in order to correct the issue.
9. Faulty Throttle Pedal Position Sensor
A faulty throttle pedal position sensor can also cause the RPMs to go up and down. This sensor is responsible for sending information to the car’s computer about how far you have depressed the pedal. If it is malfunctioning, it can cause the engine to rev up and down erratically. There are a few things you can do to troubleshoot a faulty throttle pedal position sensor. First, check the wiring and connectors to make sure they are all connected and in good condition. Next, check the sensor itself for any damage or debris that may be interfering with its operation.
10. Transmission Issues
If the transmission is not working correctly, it can cause the engine to struggle. This can lead to the RPMs spiking or dropping unexpectedly. First, make sure that your transmission fluid is at the correct level. If it is low, adding more fluid may help to fix the problem. You can also try changing the transmission fluid altogether, as this may help to get rid of any issues that you are having. If neither of those things seems to help, it is possible that there is an issue with your transmission itself. In this case, you will need to take it to a mechanic.
11. Problem With The Combustion Process
If something is wrong with the combustion process, it can cause the RPM to go up and down. One possible problem is a misfire. This happens when the air/fuel mixture doesn’t ignite properly, and it can cause the RPM to spike. Another problem is detonat

Hello, thanks for the video, very well done. I ask you, what is the name of that valve? And if it is defective, it can cause an unstable idle and go up and down from 1000 to 2000 rpm when the car is running? Thanks and regards
This valve is called ΄΄Vacuum Switching Valve΄΄ and:
1. What does a vacuum switch valve do?
The vacuum switching valve (VSV) which controls the vacuum supply to the actuator is normally closed and passes vacuum to the actuator when it is energized by the ECU. By energizing the VSV vacuum is passed to the actuator, closing the air control valve. This effectively lengthens the intake manifold run.
2. What are the symptoms of a bad vacuum switching valve?

b. Your car has poor performance.
c. You have increased fuel consumption.
d. Your car frequently stalls when idling.
e. You can smell fuel.
f. Your engine management light stays on.
g. Your car produces more emissions.
3. How does a switching valve work?
The switching valve is required to direct hot feed to either drum A or drum B. The valve also has the bypass position to divert flow back to the fractionator for or during emergencies. This valve is found in delayed coker units where multi-port valves are required in high-temperature coking applications.

@@enriqueatala2567 My friend, I think I have found the solution to your problem: the problem is in the throttle body and specifically in the idle air control valve. You may have a dirty or failing idle air control valve causing your engine idle to fluctuate.

Σας παρακαλούμε
My friend this job (if it's a 10th gen Corolla model like mine) then it's a very difficult, laborious and time consuming process that very few people can do (remove and replace). It is inside a plastic casing which is not visible, that is, it is in a hidden place.
What is the EVAP system on a Toyota Corolla?
Evaporative Emission Control (EVAP) System - Code P0441 Diagnostic
The EVAP system manages gasoline vapor evaporation from the gas tank and fuel systems. It consists of several parts but works relatively simply. Vapors from the gasoline tank, as the vehicle sits, idles, ambient temperatures change, etc. can begin to exert pressure on the fuel tank.
How does Toyota EVAP system work?
Fuel vapors from the fuel tank are captured in the charcoal canister and extracted when the engine is running. If vapor pressure increases in the fuel tank or during refueling events, excess pressure is released from the normally open vent valve via the canister air filter.
How to fix P0441
To repair error code P0441, you'll need to first diagnose the code and determine exactly what the issue is. Replacing the gas cap and purge valve are two of the most common fixes for this error code. However, there could be other issues that trigger this code, like disconnected or damaged wires within your EVAP system.
What are the components of car EVAP system?
EVAP systems have been required on gasoline powered vehicles since the 1970s. A typical system consists of the fuel tank, an EVAP vapor storage canister full of charcoal, valves, hoses and a sealed fuel tank gas cap. The EVAP system is designed to stop fuel system fumes from leaking directly into the atmosphere.

ما هو نظام EVAP في تويوتا كورولا؟
نظام التحكم في الانبعاثات التبخرية (EVAP) - الكود P0441 التشخيصي
يقوم نظام EVAP بإدارة تبخر بخار البنزين من خزان الغاز وأنظمة الوقود. يتكون من عدة أجزاء ولكنه يعمل بشكل بسيط نسبيًا. يمكن للأبخرة المنبعثة من خزان البنزين أثناء وقوف السيارة في وضع الخمول وتغير درجات الحرارة المحيطة وما إلى ذلك أن تبدأ في ممارسة الضغط على خزان الوقود.
كيف يعمل نظام تويوتا EVAP؟
يتم التقاط أبخرة الوقود من خزان الوقود في علبة الفحم ويتم استخراجها عند تشغيل المحرك. إذا زاد ضغط البخار في خزان الوقود أو أثناء أحداث التزود بالوقود، فسيتم تحرير الضغط الزائد من صمام التهوية المفتوح عادة عبر مرشح الهواء العلبة.
كيفية إصلاح P0441
لإصلاح رمز الخطأ P0441، ستحتاج أولاً إلى تشخيص الرمز وتحديد المشكلة بالضبط. يعد استبدال غطاء الغاز وصمام التطهير من أكثر الإصلاحات شيوعًا لرمز الخطأ هذا. ومع ذلك، قد تكون هناك مشكلات أخرى تؤدي إلى ظهور هذا الرمز، مثل الأسلاك المنفصلة أو التالفة داخل نظام EVAP الخاص بك.
ما هي مكونات نظام EVAP للسيارة؟
أصبحت أنظمة EVAP مطلوبة في المركبات التي تعمل بالبنزين منذ السبعينيات. يتكون النظام النموذجي من خزان الوقود، وعلبة تخزين بخار EVAP المملوءة بالفحم، والصمامات، والخراطيم، وغطاء غاز محكم الغلق لخزان الوقود. تم تصميم نظام EVAP لمنع أبخرة نظام الوقود من التسرب مباشرة إلى الغلاف الجوي.

@@EmmanuelTANITYA Il existe plusieurs causes pour lesquelles votre voiture perd considérablement de la puissance lors de l'accélération. Les causes les plus courantes pour lesquelles une voiture n'accélère pas pendant la conduite incluent un capteur défectueux, des filtres à carburant ou à air contaminés, ou une courroie de distribution (ou chaîne) défectueuse.
