I have a 2007 vw Rabbit 2.5L. I already replaced the coils and plugs, the first Fuel injector (which was giving off a code) and replaced all of the fuel injector top and bottom O-Rings. It’s still sputtering. I Do have thicker Oil in it, but it was running fine for the past 6 months. It loses power during acceleration and around 3-4th gear.
Hi there, Given your 2007 VW Rabbit's symptoms of sputtering and losing power during acceleration, even after replacing the coils, plugs, and a fuel injector, it’s possible that: 1. Mass Air Flow (MAF) Sensor: A faulty MAF sensor can cause these issues. Try cleaning or replacing it. 2. Throttle Body: A dirty or malfunctioning throttle body can affect acceleration. 3. Fuel Pump/Filter: Check the fuel pump and filter for proper fuel delivery. 4.Vacuum Leaks: Inspect for any vacuum leaks, which can cause similar symptoms. 5. PCV Valve: A malfunctioning PCV valve can lead to power loss and sputtering. Addressing these components should help diagnose and fix the problem.
I have an 08 tacoma 2.7l i4, i have had misfires and variable low idle/vibration, but if you give it a little gas, it runs good. I just got the haynes manual and read about this sensor. I was going to pull the head and have it checked. Do you think it might be this vvt sensor?
Given the symptoms you're describing with your 2008 Toyota Tacoma 2.7L I4 - misfires and variable low idle along with vibration that improves when giving it gas - it is indeed plausible that the issue could be related to the Variable Valve Timing (VVT) sensor, especially since VVT plays a crucial role in engine timing and performance. The VVT system adjusts the timing of the camshafts to optimize engine performance and efficiency. If the VVT sensor (often referred to as the VVT solenoid) is malfunctioning, it could cause the timing to be off, leading to misfires and rough idling. Before you consider pulling the head, which can be quite labor-intensive and expensive.
such as a timing chain tensioner that lacks oil pressure, causing inaccurate timing and can cause the engine to vibrate. Because when the engine rpm is increased, the vibration disappears. So it could be the tensioner that has a problem, or the oil pressure that has a problem.
Good video thank you, My car is Santa Fe sport 2018 , if this sensor vvt selenoid have a problem affecting the line of the sprocket phaser too ? Let me know my friend because I’m confused I don’t know if the problem is vvt selenoid sensor or sprocket phaser , my car all the time is accelerating , please my friend let me know 🙏
Hi, way to go for choosing a Lexus!. It sounds like your Lexus IS250 might indeed be experiencing a problem related to the Variable Valve Timing (VVT) system, particularly the VVT solenoid. The rattle you're hearing upon startup, which dissipates after a couple of seconds, could be due to the VVT solenoid failing to properly control the flow of oil to the VVT chain on initial startup. This is relatively common in vehicles as they age and accumulate mileage.
I saw your comment. That's a bad tensioner. So what happens is oil leaks out of the tensioner when the car sits and the change loose when you start it and it rebuilts pressure
Not a bad tensioner. It's the vtc cam it holds oil pressure. When it loses the ability to hold oil, and drains, it rattles, until it gain pressure again on start up. Look up VTC actuator for lexus
Man i really hope you read this. My 2013 elantra has the 1.8 in it, and at around 3k rpms it soits and sputters like crazy. Everything is fine at idle though. Could the solenoid be the issue or the chain itself? Edit: its NOT theowing any check engine codes either
Hi, I Have a 2013 altima, it idles very rough, I already changed the Battery, Plugs, Coils, Engine support and did a injector and sensor cleaning, but still the idle is very rough, specially when accessories are on, it does not stall and runs perfect on high RPM, it also does not throw any codes referring to the solenoid, Was it possible to have faulty solenoids without any codes??should I replace them now? Cause I dont want to spend more without fixing the issue. thanks,
I have a MK6 Golf R (under warranty) and I’ve had these symptoms and had it towed to a local Volkswagen Dealership. They went through the tune up new coil packs and spark plugs. They said they still had a misfire and a code for low cam position was throw so they changed the N205 valve. They still say that my car is running rough so now they said it’s the cam phaser but it hasn’t been changed yet. My car has been at the dealership since August 19th of this year and it’s still there now. What do you think is going on? Have they been diagnosing this properly or are they dragging this out. Also communication is lacking. What do you think my issue is?
My Nissan primera p12 stalls when rpm drops too much when I come to a stop light and gives p1110 which is intake valve timing bank 1 but I took out solenoid cleaned it and tested with a 12 v bat and it openes and closes so I'm lost
My car runs great cause everything great stays on the number one on tachometer oil is great. A problem little tap and up by the camp shop phaser results back.
It sounds like you're saying your car generally runs well because all the indicators (like oil pressure) are in the optimal range on your dashboard. However, you're experiencing a slight issue, possibly a tapping noise, which was diagnosed at a repair shop as related to the camshaft phaser. This component helps improve the engine's efficiency by adjusting the timing of the camshaft. If it's faulty, it might need repair or replacement to resolve the noise and ensure your engine runs smoothly.
Hi, had a bearing Knock on my audi, cut the crank, replaced pistons, rings, bearings, schemed the head replaced valves on cylinder 3 and i still keep getting misfire on cylinder 3, the compression in the cylinder is quite low but its low on cylinder 2 and 4 as well, but only getting the misfire on cylinder 3 on the VCDS and high values for misfiring on cylinder 3, could the VVT cause this as its strange that only cylinder 3 is misfiring so much, also the misfire is mostly at low rpms, some help would be appreciated.
Hi Naeem, did you manage to find the cause?. A bad VVT solenoid can cause that especially on Audi's but my hunch tells me you might have a bad fuel injector on cylinder 3.
Hi, Yes, a common issue with the VVT-i system not working in a Toyota Vitz 1.3 VVT-i could indeed be the solenoid. The VVT-i solenoid controls oil flow to adjust the timing of the camshaft for optimal engine performance. If it's faulty or clogged, it can prevent the VVT-i system from functioning properly. It's advisable to check the solenoid for any signs of oil blockage or electrical issues.
Hello, I have a 07 Nissan Altima and upon start up, the car shakes, on warm up under acceleration it makes a ticking noise 1.5k rpm to rev limit could it be a vvt solenoid or a piston, rings, or something else?
The shaking on startup and ticking noise during acceleration could be caused by several issues, such as: 1. Faulty VVT solenoid 2. Low oil level or poor oil quality 3. Worn valve lifters or camshaft lobes 4. Exhaust manifold leak 5. Spark plug or ignition coil issues While worn piston rings are a possibility, they are less likely to cause the specific symptoms you described. It's best to have a mechanic diagnose the problem to determine the exact cause and appropriate repair.

I’m changing out a bad water pump in my ‘17 Ford Explorer. At 168,000 miles it’s probably be wise to just go and replace the VVT solenoid right? Hell I’m changing out the alternator too since it’s never been changed.
I changed the VVT solenoid on the bank 2 side because that was the problematic side. But now I’m having a shaking issue when I slow to a stop. When I make the complete stop, it stops shaking. Should I change the bank 1 side also? Perhaps it’s something else? Any help would be greatly appreciated and thank you for making this video.
And the way to check the solenoid is by taking it out and have a battery connect directly to the selenoid u should hear a tick sound ( when the selenoid open and close)
Hi, when starting my Volkswagen Passat 2017, an error message sometimes appears. After taking it to the workshop for diagnostics, they mentioned that according to the computer, one of the electronic engine VVT components is faulty and needs replacement. Is this accurate? Appreciate for your input

Hello, I have a corolla 2015 and my car makes a rattling tac tac tac noise when is very hot outside 115°f. I just changed the oil thinking it was probably the oil that was too old but it keeps doing it, could it be the vvti solenoid or the entire vvti system or perhaps the 0w20 oil that they recommend is too thin for this extreme weather, that thing is like water
This could be my issue.. the scan code on my 2007 camry is p0016 Crankshaft position correlation ( bank 1 sensor a) Is this the reason why my car is accelerating on hill and misfiring
Hi. My car sometimes rattles 1-2 seconds after startup. Its not got timing chain. Can it be vvt solenoids? Will it damage something if not replaced? No fault codes are present, and no other symptoms.
Hi. Yes it could be related to the solenoids. If the VVT solenoids are failing or are clogged, it's possible that you won't see immediate fault codes or other symptoms but experience some rattles. But since its only 1-2 seconds after startup, I wouldn't be worried just yet.
While this is a common problem in cars with high mileage it's better to scan the ECU for codes rather than looking for symptoms to identify a problem. Rough idling, misfires, poor starts and other symptoms could be caused by other conditions. Many DIYs jump to conclusions and end up ' fixing' things that had nothing to do with the problem. Most VVT failures usually result from dirty screens which in turn are the result of irregular oil change intervals. If a VVT code is present, remove the valves ( intake and exhaust) and clean the screens with a solvent such as brake cleaner. If that doesn't solve the problem then replace the vvts. Symptoms are only a ball park approach to a problem that can tell you which components to check. For an accurate diagnosis identify the part that is failing. This will save time, money and frustration.
Hi, Yes, a bad VVT (Variable Valve Timing) solenoid can cause air suction from the oil dipstick tube. This happens because a malfunctioning VVT solenoid can lead to improper engine timing and increased crankcase pressure. The increased pressure in the crankcase can cause air to be drawn in through the oil dipstick tube.
Have my 2015 Highlander limited v6. Code p0012. The car doesn’t allow the awd drive to be used nor the eco mode. Doesn’t have noticeable shaking when idle and recently got and oil changed with a trip to Michigan behind it with no issues. This happen on my way home from NY 7 hour trip. Half way Check engine light came one. Couldn’t use the awd system after that. Drove it slowly home and out the scanner. I haven’t got the solenoid yet my question is should go a head and just replace it or should I be concerned about the timing chain itself?
@@bradleyrivenbark946 just erased the code and changed the oil. It went away. However I’m hearing the rattle noise more noticeable when idle. I don’t think it has anything to do with the timing chain in most cases. I bought the VVTI SOLENOID AT Napa $134. Haven’t changed it yet but that was next step before the code went away and all systems came back. Ever since I haven’t had any issues. I still intent buying the other 3 remaining VVTI solenoids. Keep in mind bank 1 is at the back near the windshield. Bank 2 is at the front. There’s 2 exhaust VVTIs solenoids and two intake solenoids. One of each at both banks. Apparently they get stuck when oil is dirty or low. They are very fragile and prone to failure if almost anything that’s not oil gets in between the little valves inside said solenoids. Best prevention change your oil every 3k that’s been key imo. Don’t go for the intervals even tho this V6 is not turbo it does run Hot. 🥵 Pro tip I leaned with these issue; erase the code at least once to see if it comes back. Before buying parts. And check your oil level make sure is clean and closer to the F as possible.
This sounds like a blown head gasket. Your oil consumption is because your oil is mixing with your coolant & being burned off hence the smoke coming from the exhaust, i would fix that before you engine blows.
What kind of car? If it's any car with the 2.4L Toyota engine, it could be buildup on your piston rings. There are processes to help this issue and greatly reduce oil consumption. I'm surprised he went with "blown head gasket" right away without even asking what color the smoke is. If its grey/blue/black-ish, it's from burning oil. If it's white or very very light in color, then it could be the head gasket. Also, if you're only burning oil and not also going through coolant, it isn't the head gasket.
I have a 2006 Nissan maxima I can drive it for 30 minutes fine at whatever rpm I want but after 30min my car will not go up 3k rpm on all my gears and the car want to die and the rpm go up and down when I’m idle and driving could it be the vvt solenoid or timing chain skipping teeth ?
Hi, Your issue, where the car operates normally for 30 minutes before experiencing RPM limitations and instability, could potentially be related to the VVT solenoid, but it might also involve other factors such as fuel delivery problems, a clogged catalytic converter, or an issue with the engine's electronic control system, including sensors like the MAF or O2 sensors. While a timing chain skipping teeth is possible, it's less likely to cause intermittent problems and would typically result in more constant and severe running issues or the engine not running at all. Before focusing on the VVT solenoid or timing chain, consider having the vehicle's computer scanned for trouble codes and checking for any issues with fuel pressure or exhaust flow restrictions.
I have nissan priemra 1998 What if my car stuck when i shift to R and i need to accelerate so that it can move and sometimes Gear D too, is it possible solenoid?
I’m currently trying to fix multiple misfires on my ‘16 IS300 with 35k miles. Replaced coils and spark plugs and the result was misfires on 5 cylinders! Took it to a shop and they suspect it’s due to the non oem parts I used. I plan on getting oem but that still doesn’t account for the initial misfires. I’m wondering if the vvti solenoid could be the cause. There have been no codes mentioning it. Only cylinder misfire codes. Thought? Thanks for any help!
Hi John, Yes, these solenoids can indeed cause misfires, and the tricky part is that they can lead to a lot of random misfires. I once owned a V8 Audi S5, and it started misfiring on one bank despite my plugs, coils, and injectors being fairly new. I even carbon cleaned my engine. That's when I decided to change the solenoids on both banks. As a mechanic, I know that if one component starts to fail, others may soon follow. Regarding your '16 IS300 with 35k miles, it's concerning that replacing coils and spark plugs led to misfires on 5 cylinders. The shop suspects it might be due to non-OEM parts, but even if you switch to OEM parts, it doesn't explain the initial misfires. It's possible that the VVTi solenoid could be a culprit, despite no codes mentioning it, as you've only seen cylinder misfire codes. It might be worth investigating the solenoid further. Hope this helps! Let me know if you have any more questions or need further assistance.
@@HonestMechanicChannel thanks for the quick response! The only other suspicion he had was carbon build up. Which turned out to be quite minimal. So he basically circled back to plugs and coils. I had seen some mention of the solenoids but couldn’t remember what they were called when I tried to bring it up. Seems possible. The reason im unsure is because the codes referenced seem to be different than the misfire codes im getting. Thanks again!
Hi Aunbriell, A faulty VVT (Variable Valve Timing) solenoid typically doesn't prevent an engine from turning over; instead, it can cause issues like poor engine performance, increased fuel consumption, rough idling, or a check engine light. The VVT solenoid is responsible for controlling the flow and timing of oil to the VVT system to adjust the engine's valve timing. If it fails, you'll likely notice performance problems, but the engine will still turn over if the battery and starter are in good condition. If your Chrysler 200 is not turning over at all (i.e., the engine does not crank when you try to start it), the issue is likely related to the battery, starter motor, ignition switch, or a seized engine. A seized engine can indeed prevent the car from turning over, but this would typically be accompanied by a history of serious engine problems, such as overheating or lack of oil. To diagnose the issue, you should: 1. Check the battery voltage and ensure it's fully charged. 2. Listen for a click when you try to start the engine; a single click can indicate a problem with the starter. 3. Check for any visible signs of oil leakage or damage under the engine which could suggest serious internal issues. 4. If possible, try manually turning the engine with a breaker bar and socket on the crankshaft pulley bolt (only if you're experienced with mechanical work). If the engine cannot be manually turned, it might be seized. If you're unsure or not experienced with car repairs, it's a good idea to have a professional mechanic take a look to accurately diagnose and resolve the issue.
Hi Mate wen i start the car first attempt in the morning its cuts of and then it starts with a rattle , chain been replaced 2 month ago could it be the VVT sprocket and VVT solenoid ?it gives a camshaft sensor error wen you scan the car
Did it take care of your issue with new solenoids? I am having same issue chain seems good, cold start rattle for 2 seconds and have a intake solenoid code. Was brainstorming thinking if solenoid is bad maybe the oil pressure to vvt is not present at start up causing it to rattle until oil makes its way in there
Hi there, I suggest you first clean them properly before replacing them to avoid spending before being sure if the issue is the vvt solenoid itself or something at play.
Yo my man, quick question ❓ will these being bad make a car backfire and rPmZ not to work all of a sudden after changing starter, oil, manifold intake just minutes ago or “NO “
Hey man, managed to get it sorted? Yes, faulty VVT solenoids can potentially cause backfiring and RPM issues, as they affect engine timing. However, if these problems started right after changing the starter, oil, and intake manifold, it's also worth double-checking those areas for any installation errors or disconnected sensors.
How about after all those changes there my man and still no change, it’s LOW ENGINE COMPRESSION and it’ll be going to the shop nDa morning to get engine #3️⃣, all sensors from 0², crankshaft, both camshafts, VvTs,plugs, coils all.,.smh 🤣😂🤨,Ecotec motors are weak but I thank you a million dude
Hi Sean, Finding metal shavings on your VVT solenoid for a 2014 Chevy Malibu could indicate wear in the engine's internal components, possibly due to inadequate lubrication or failing parts. It’s important to thoroughly clean the solenoid, check for further damage, and replace the engine oil and filter promptly. Consider having a mechanic inspect the engine to diagnose and address the root cause of the metal shavings. Also I recommend replacing the solenoid
Hi guys i have an SQ5 2017 B8.5 , recently a fault code has appeared “P1B1C00” as i found out it’s related to the coolant system codes , i changed a new water pump and some other check up but still there .

My 15 rogue runs great at start up, after warmed up it vibrates at idle .. no check engine light, however scanner says vvt monitor bank 1 status fail .. what could that be ?
Hi, suggests a possible issue with the Variable Valve Timing (VVT) system. The VVT system is designed to improve engine performance and efficiency by altering the timing of the valve opening and closing. Here are a few possibilities (Most common to least) 1. VVT Solenoid or Actuator Problem: The VVT solenoid controls the flow of oil to the VVT chain and gears. If it's malfunctioning or clogged, it can affect the timing, leading to rough idling. 2. Oil Quality and Level: Low or dirty oil can negatively impact the VVT system. Since VVT relies on hydraulic pressure (which comes from the engine oil), insufficient or contaminated oil could hinder its operation. 3. Timing Chain or Belt Issue: If your Rogue uses a timing chain (which is more likely) and it's stretched or not functioning correctly, it could affect the VVT system.
@@HonestMechanicChannel Thank you ! I’m thinking the chain stretched since I change oil every 3,000 miles, I would think the solenoids would be ok with that interval, and chain for that matter. The car is at 77,800 miles the chain shouldn’t be an issue yet , but I guess could be. I don’t have the facility to do it myself, now I have to find a reputable mechanic who will be honest about what it really needs.
My 16 maxima is telling me the same exact thing vvt solenoid bank 1... in which my mechanic ask if I had and oil change recently and that's what happened. They put the wrong or dirty oil in the motor caused mines. My car takes 2 to 3 sec to start up
I have a 2019 Infiniti Q50 3.0t (94K miles). My car was driving very sluggish when I was trying to accelerate. Does this has anything to do with my catalytic converter? I ran my OBD scanner and got the two codes: P0012 - A Camshaft Position Timing Over - Retarded Bank 1 P0022 - A Camshaft Position Timing Over - Retarded Bank 2
Hi, The sluggish acceleration and the diagnostic trouble codes P0012 and P0022 are related to the variable valve timing (VVT) system, not the catalytic converter. These codes indicate that the camshaft timing is retarded (delayed) on both banks of the engine. This issue can cause reduced engine performance and sluggish acceleration. I would first check the cam position sensors then move to vvt solenoids
P0011 is a diagnostic trouble code (DTC) that indicates a timing issue related to the "A" camshaft on bank 1 of the engine. The code description is "Intake Camshaft Position Timing - Over-Advanced (Bank 1)". This means that the intake camshaft on bank 1 is more advanced than the ECU expects it to be. Possible causes for this code include: 1. Low engine oil level or dirty oil 2. Stretched or jumped timing chain 3. Faulty camshaft phaser or actuator 4. Camshaft position sensor issue 5. Sludge or debris in the oil passages 6. Wiring issues or damaged connectors related to the camshaft position sensor or actuator In rare cases, a faulty ECU

Not a bad tensioner. It's the vtc cam it holds oil pressure. When it loses the ability to hold oil, and drains, it rattles, until it gain pressure again on start up.

Man i really hope you read this. My 2013 elantra has the 1.8 in it, and at around 3k rpms it soits and sputters like crazy. Everything is fine at idle though. Could the solenoid be the issue or the chain itself?
Edit: its NOT theowing any check engine codes either
Great and informative video. Thanks
Thank you for watching and for your kind words!
Hi, I Have a 2013 altima, it idles very rough, I already changed the Battery, Plugs, Coils, Engine support and did a injector and sensor cleaning, but still the idle is very rough, specially when accessories are on, it does not stall and runs perfect on high RPM, it also does not throw any codes referring to the solenoid,
Was it possible to have faulty solenoids without any codes??should I replace them now? Cause I dont want to spend more without fixing the issue. thanks,
Same what happen with u
I have a 2020 V6 Chevy Blazer outputting P0024 code. When shifting 1-3 gear she shakes. Runs very smooth after that. Could it be the selonoide?
I have a MK6 Golf R (under warranty) and I’ve had these symptoms and had it towed to a local Volkswagen Dealership. They went through the tune up new coil packs and spark plugs. They said they still had a misfire and a code for low cam position was throw so they changed the N205 valve. They still say that my car is running rough so now they said it’s the cam phaser but it hasn’t been changed yet. My car has been at the dealership since August 19th of this year and it’s still there now. What do you think is going on? Have they been diagnosing this properly or are they dragging this out. Also communication is lacking. What do you think my issue is?
Can these throw a knock sensor code?
If is safe to drive with the vvt solenoid damage,? Can caused other damages?
My Nissan primera p12 stalls when rpm drops too much when I come to a stop light and gives p1110 which is intake valve timing bank 1 but I took out solenoid cleaned it and tested with a 12 v bat and it openes and closes so I'm lost
I have a Mazda I tested my vvt with clips. I got either no click or rapid clicking. Probly bad? I read the Olms on it they where around 7.
I have rouge idle not super rough but its there and sound coming from the engine almost sound like injectors, but the engine perfomence is fine
My car runs great cause everything great stays on the number one on tachometer oil is great. A problem little tap and up by the camp shop phaser results back.
It sounds like you're saying your car generally runs well because all the indicators (like oil pressure) are in the optimal range on your dashboard. However, you're experiencing a slight issue, possibly a tapping noise, which was diagnosed at a repair shop as related to the camshaft phaser. This component helps improve the engine's efficiency by adjusting the timing of the camshaft. If it's faulty, it might need repair or replacement to resolve the noise and ensure your engine runs smoothly.
Hi, had a bearing Knock on my audi, cut the crank, replaced pistons, rings, bearings, schemed the head replaced valves on cylinder 3 and i still keep getting misfire on cylinder 3, the compression in the cylinder is quite low but its low on cylinder 2 and 4 as well, but only getting the misfire on cylinder 3 on the VCDS and high values for misfiring on cylinder 3, could the VVT cause this as its strange that only cylinder 3 is misfiring so much, also the misfire is mostly at low rpms, some help would be appreciated.
Hi Naeem, did you manage to find the cause?. A bad VVT solenoid can cause that especially on Audi's but my hunch tells me you might have a bad fuel injector on cylinder 3.
Hi i have a toyota vitz 13 vvti and the vvti is not working can it be the solenoid ?
Hi, Yes, a common issue with the VVT-i system not working in a Toyota Vitz 1.3 VVT-i could indeed be the solenoid. The VVT-i solenoid controls oil flow to adjust the timing of the camshaft for optimal engine performance. If it's faulty or clogged, it can prevent the VVT-i system from functioning properly. It's advisable to check the solenoid for any signs of oil blockage or electrical issues.
Hello, I have a 07 Nissan Altima and upon start up, the car shakes, on warm up under acceleration it makes a ticking noise 1.5k rpm to rev limit could it be a vvt solenoid or a piston, rings, or something else?
The shaking on startup and ticking noise during acceleration could be caused by several issues, such as:
1. Faulty VVT solenoid
2. Low oil level or poor oil quality
3. Worn valve lifters or camshaft lobes
4. Exhaust manifold leak
5. Spark plug or ignition coil issues
While worn piston rings are a possibility, they are less likely to cause the specific symptoms you described. It's best to have a mechanic diagnose the problem to determine the exact cause and appropriate repair.
Is the supposed to be volt at idle in the solenoid terminals?
My Hyundai Elantra's VVT solenoid connection is broken.. Means its not connected but still car is running smoothly, but i noticed one issue that my Transmission wouldn't shift from "Automatic D" to manual gear
I’m changing out a bad water pump in my ‘17 Ford Explorer. At 168,000 miles it’s probably be wise to just go and replace the VVT solenoid right? Hell I’m changing out the alternator too since it’s never been changed.
i would for sure for piece of mind since you are in it anyway
I changed the VVT solenoid on the bank 2 side because that was the problematic side. But now I’m having a shaking issue when I slow to a stop. When I make the complete stop, it stops shaking. Should I change the bank 1 side also? Perhaps it’s something else? Any help would be greatly appreciated and thank you for making this video.
Put the new solenoid in the other place and see if the issue stop or no . Maybe the shaking is from brake pads or brake hub
And the way to check the solenoid is by taking it out and have a battery connect directly to the selenoid u should hear a tick sound ( when the selenoid open and close)
Thanx
Hi, when starting my Volkswagen Passat 2017, an error message sometimes appears. After taking it to the workshop for diagnostics, they mentioned that according to the computer, one of the electronic engine VVT components is faulty and needs replacement. Is this accurate? Appreciate for your input
Hi Richard, Apologies for the late response. what was the error message you got and was the car running rough?
I have a 2010 vw tiguan 2.0 tsi and one piston is misfiring i checked ignition coils sparks injector they were good and i even redone the timing chain and it still got less power and it still misfire on cylinder 4
I have a p1346 , and I assume I need to change the vvt . But to be honest I haven’t found any information on that specific code online
Hello, I have a corolla 2015 and my car makes a rattling tac tac tac noise when is very hot outside 115°f. I just changed the oil thinking it was probably the oil that was too old but it keeps doing it, could it be the vvti solenoid or the entire vvti system or perhaps the 0w20 oil that they recommend is too thin for this extreme weather, that thing is like water
Possibly knock sensor
This could be my issue.. the scan code on my 2007 camry is p0016
Crankshaft position correlation ( bank 1 sensor a)
Is this the reason why my car is accelerating on hill and misfiring
I can say for sure any symptom from video will show you check engine on dashboard
Hi. My car sometimes rattles 1-2 seconds after startup. Its not got timing chain. Can it be vvt solenoids? Will it damage something if not replaced? No fault codes are present, and no other symptoms.
Hi. Yes it could be related to the solenoids. If the VVT solenoids are failing or are clogged, it's possible that you won't see immediate fault codes or other symptoms but experience some rattles. But since its only 1-2 seconds after startup, I wouldn't be worried just yet.
@@HonestMechanicChannelthank you for the answer. I love this channel😊
Thanks, I really appreciate your support mate!
While this is a common problem in cars with high mileage it's better to scan the ECU for codes rather than looking for symptoms to identify a problem. Rough idling, misfires, poor starts and other symptoms could be caused by other conditions. Many DIYs jump to conclusions and end up ' fixing' things that had nothing to do with the problem. Most VVT failures usually result from dirty screens which in turn are the result of irregular oil change intervals. If a VVT code is present, remove the valves ( intake and exhaust) and clean the screens with a solvent such as brake cleaner. If that doesn't solve the problem then replace the vvts. Symptoms are only a ball park approach to a problem that can tell you which components to check. For an accurate diagnosis identify the part that is failing. This will save time, money and frustration.
is the engine oil light blinking while driving relate to this solenoid?
Would this cause air suction from the oil dipstick tube?
Hi, Yes, a bad VVT (Variable Valve Timing) solenoid can cause air suction from the oil dipstick tube. This happens because a malfunctioning VVT solenoid can lead to improper engine timing and increased crankcase pressure. The increased pressure in the crankcase can cause air to be drawn in through the oil dipstick tube.
Nice video! Mine is lealing oil extremely, should I replace it? Or just replace the O Ring and use sealer?
Thanks. depends on your budget, often times just replacing the seals works 100% but I personally recommend replacing the leaky VVT.
@@HonestMechanicChannel tnx, better not using the car and fixing it next month
Have my 2015 Highlander limited v6. Code p0012. The car doesn’t allow the awd drive to be used nor the eco mode. Doesn’t have noticeable shaking when idle and recently got and oil changed with a trip to Michigan behind it with no issues. This happen on my way home from NY 7 hour trip. Half way Check engine light came one. Couldn’t use the awd system after that. Drove it slowly home and out the scanner. I haven’t got the solenoid yet my question is should go a head and just replace it or should I be concerned about the timing chain itself?
Did you figure out what it was?
I have the same issue, replaced spark plugs, cylinder coil but still codes P0011 and P0021 comes back.
@@bradleyrivenbark946 just erased the code and changed the oil. It went away. However I’m hearing the rattle noise more noticeable when idle. I don’t think it has anything to do with the timing chain in most cases. I bought the VVTI SOLENOID AT Napa $134. Haven’t changed it yet but that was next step before the code went away and all systems came back. Ever since I haven’t had any issues. I still intent buying the other 3 remaining VVTI solenoids. Keep in mind bank 1 is at the back near the windshield. Bank 2 is at the front. There’s 2 exhaust VVTIs solenoids and two intake solenoids. One of each at both banks. Apparently they get stuck when oil is dirty or low. They are very fragile and prone to failure if almost anything that’s not oil gets in between the little valves inside said solenoids. Best prevention change your oil every 3k that’s been key imo. Don’t go for the intervals even tho this V6 is not turbo it does run Hot. 🥵
Pro tip I leaned with these issue; erase the code at least once to see if it comes back. Before buying parts. And check your oil level make sure is clean and closer to the F as possible.
I have a 2013 Altima
It idles rough and the engine dies when I stop at lights or a stop sign
Could that be the issue ?
Mine does that too. You should clean them first and if it stops that issue then it is the vvts and just replace
Yes. I replaced all 3. The car is running smooth now.
@@93everything dude that is f n awesome I'm going to do that as well!
Really glad you managed to sort it out!
@@93everythingthere are 3 VVT solenoids? I thought there was only one per bank?
Will this cause my exhaust to blow smoke. I'm a delivery driver and I go thru 2gts of oil a day
This sounds like a blown head gasket. Your oil consumption is because your oil is mixing with your coolant & being burned off hence the smoke coming from the exhaust, i would fix that before you engine blows.
What kind of car? If it's any car with the 2.4L Toyota engine, it could be buildup on your piston rings. There are processes to help this issue and greatly reduce oil consumption. I'm surprised he went with "blown head gasket" right away without even asking what color the smoke is. If its grey/blue/black-ish, it's from burning oil. If it's white or very very light in color, then it could be the head gasket. Also, if you're only burning oil and not also going through coolant, it isn't the head gasket.
I’ve got code p000A but none of these symptoms it idles fine on tick over with slight tiny misfire hear and that in cylinder 4
I have a 2006 Nissan maxima I can drive it for 30 minutes fine at whatever rpm I want but after 30min my car will not go up 3k rpm on all my gears and the car want to die and the rpm go up and down when I’m idle and driving could it be the vvt solenoid or timing chain skipping teeth ?
Hi, Your issue, where the car operates normally for 30 minutes before experiencing RPM limitations and instability, could potentially be related to the VVT solenoid, but it might also involve other factors such as fuel delivery problems, a clogged catalytic converter, or an issue with the engine's electronic control system, including sensors like the MAF or O2 sensors. While a timing chain skipping teeth is possible, it's less likely to cause intermittent problems and would typically result in more constant and severe running issues or the engine not running at all. Before focusing on the VVT solenoid or timing chain, consider having the vehicle's computer scanned for trouble codes and checking for any issues with fuel pressure or exhaust flow restrictions.
I have nissan priemra 1998 What if my car stuck when i shift to R and i need to accelerate so that it can move and sometimes Gear D too, is it possible solenoid?
I’m currently trying to fix multiple misfires on my ‘16 IS300 with 35k miles. Replaced coils and spark plugs and the result was misfires on 5 cylinders! Took it to a shop and they suspect it’s due to the non oem parts I used. I plan on getting oem but that still doesn’t account for the initial misfires. I’m wondering if the vvti solenoid could be the cause. There have been no codes mentioning it. Only cylinder misfire codes. Thought? Thanks for any help!
Hi John,
Yes, these solenoids can indeed cause misfires, and the tricky part is that they can lead to a lot of random misfires. I once owned a V8 Audi S5, and it started misfiring on one bank despite my plugs, coils, and injectors being fairly new. I even carbon cleaned my engine. That's when I decided to change the solenoids on both banks. As a mechanic, I know that if one component starts to fail, others may soon follow.
Regarding your '16 IS300 with 35k miles, it's concerning that replacing coils and spark plugs led to misfires on 5 cylinders. The shop suspects it might be due to non-OEM parts, but even if you switch to OEM parts, it doesn't explain the initial misfires. It's possible that the VVTi solenoid could be a culprit, despite no codes mentioning it, as you've only seen cylinder misfire codes. It might be worth investigating the solenoid further.
Hope this helps! Let me know if you have any more questions or need further assistance.
@@HonestMechanicChannel thanks for the quick response! The only other suspicion he had was carbon build up. Which turned out to be quite minimal. So he basically circled back to plugs and coils. I had seen some mention of the solenoids but couldn’t remember what they were called when I tried to bring it up. Seems possible. The reason im unsure is because the codes referenced seem to be different than the misfire codes im getting. Thanks again!
@@johnfriedman3463did you ever figure out what the cause of your random misfire was?
I have a Chrysler 200 I wanna know if this can be a reason my car won’t turn can it this instead of me thinking an engine locked up
Hi Aunbriell, A faulty VVT (Variable Valve Timing) solenoid typically doesn't prevent an engine from turning over; instead, it can cause issues like poor engine performance, increased fuel consumption, rough idling, or a check engine light. The VVT solenoid is responsible for controlling the flow and timing of oil to the VVT system to adjust the engine's valve timing. If it fails, you'll likely notice performance problems, but the engine will still turn over if the battery and starter are in good condition.
If your Chrysler 200 is not turning over at all (i.e., the engine does not crank when you try to start it), the issue is likely related to the battery, starter motor, ignition switch, or a seized engine. A seized engine can indeed prevent the car from turning over, but this would typically be accompanied by a history of serious engine problems, such as overheating or lack of oil.
To diagnose the issue, you should:
1. Check the battery voltage and ensure it's fully charged.
2. Listen for a click when you try to start the engine; a single click can indicate a problem with the starter.
3. Check for any visible signs of oil leakage or damage under the engine which could suggest serious internal issues.
4. If possible, try manually turning the engine with a breaker bar and socket on the crankshaft pulley bolt (only if you're experienced with mechanical work). If the engine cannot be manually turned, it might be seized.
If you're unsure or not experienced with car repairs, it's a good idea to have a professional mechanic take a look to accurately diagnose and resolve the issue.
Hi Mate wen i start the car first attempt in the morning its cuts of and then it starts with a rattle , chain been replaced 2 month ago could it be the VVT sprocket and VVT solenoid ?it gives a camshaft sensor error wen you scan the car
Did it take care of your issue with new solenoids? I am having same issue chain seems good, cold start rattle for 2 seconds and have a intake solenoid code. Was brainstorming thinking if solenoid is bad maybe the oil pressure to vvt is not present at start up causing it to rattle until oil makes its way in there
Hello I'm hve toyota corolla runx 3zz 1,6 manual so the vvti solenoid problem, how can i do please
Hi there, I suggest you first clean them properly before replacing them to avoid spending before being sure if the issue is the vvt solenoid itself or something at play.
Yo my man, quick question ❓ will these being bad make a car backfire and rPmZ not to work all of a sudden after changing starter, oil, manifold intake just minutes ago or “NO “
Hey man, managed to get it sorted? Yes, faulty VVT solenoids can potentially cause backfiring and RPM issues, as they affect engine timing. However, if these problems started right after changing the starter, oil, and intake manifold, it's also worth double-checking those areas for any installation errors or disconnected sensors.
How about after all those changes there my man and still no change, it’s LOW ENGINE COMPRESSION and it’ll be going to the shop nDa morning to get engine #3️⃣, all sensors from 0², crankshaft, both camshafts, VvTs,plugs, coils all.,.smh 🤣😂🤨,Ecotec motors are weak but I thank you a million dude

My vvt solenoid had metal shavings on it🤦🏽♂️ for a 2014 Chevy Malibu
Hi Sean, Finding metal shavings on your VVT solenoid for a 2014 Chevy Malibu could indicate wear in the engine's internal components, possibly due to inadequate lubrication or failing parts. It’s important to thoroughly clean the solenoid, check for further damage, and replace the engine oil and filter promptly. Consider having a mechanic inspect the engine to diagnose and address the root cause of the metal shavings. Also I recommend replacing the solenoid
I’m getting p0014 on my 3.0t q50 can it still be my vvt
Hi, Yes since it is a cam related code, most likely the VVT. let me know how it goes
Hello i have a question, my engine rattles alot but when i drive for a while it goes away

These things fail so often, wish I could convert to standard timing.
Hi guys i have an SQ5 2017 B8.5 , recently a fault code has appeared “P1B1C00” as i found out it’s related to the coolant system codes , i changed a new water pump and some other check up but still there . Everything is looks brand new in the car The only symptom that i can feel is when accelerating i can feel there is something wrong between the gears when it shift from one to another . A weird sound “Trrrrrrrr” that’s the closest to the sound 😂 . I am not sure if it’s from the gear or the engine But i couldn’t find out where is the real problem . Any ideas !!
Sounds like a shift solenoid.

My 15 rogue runs great at start up, after warmed up it vibrates at idle .. no check engine light, however scanner says vvt monitor bank 1 status fail .. what could that be ?
Hi, suggests a possible issue with the Variable Valve Timing (VVT) system. The VVT system is designed to improve engine performance and efficiency by altering the timing of the valve opening and closing.
Here are a few possibilities (Most common to least)
1. VVT Solenoid or Actuator Problem: The VVT solenoid controls the flow of oil to the VVT chain and gears. If it's malfunctioning or clogged, it can affect the timing, leading to rough idling.
2. Oil Quality and Level: Low or dirty oil can negatively impact the VVT system. Since VVT relies on hydraulic pressure (which comes from the engine oil), insufficient or contaminated oil could hinder its operation.
3. Timing Chain or Belt Issue: If your Rogue uses a timing chain (which is more likely) and it's stretched or not functioning correctly, it could affect the VVT system.
@@HonestMechanicChannel Thank you ! I’m thinking the chain stretched since I change oil every 3,000 miles, I would think the solenoids would be ok with that interval, and chain for that matter. The car is at 77,800 miles the chain shouldn’t be an issue yet , but I guess could be. I don’t have the facility to do it myself, now I have to find a reputable mechanic who will be honest about what it really needs.
My 16 maxima is telling me the same exact thing vvt solenoid bank 1... in which my mechanic ask if I had and oil change recently and that's what happened. They put the wrong or dirty oil in the motor caused mines.
My car takes 2 to 3 sec to start up

I have a 2019 Infiniti Q50 3.0t (94K miles). My car was driving very sluggish when I was trying to accelerate. Does this has anything to do with my catalytic converter?
I ran my OBD scanner and got the two codes:
P0012 - A Camshaft Position Timing Over - Retarded Bank 1
P0022 - A Camshaft Position Timing Over - Retarded Bank 2
Hi, The sluggish acceleration and the diagnostic trouble codes P0012 and P0022 are related to the variable valve timing (VVT) system, not the catalytic converter. These codes indicate that the camshaft timing is retarded (delayed) on both banks of the engine. This issue can cause reduced engine performance and sluggish acceleration. I would first check the cam position sensors then move to vvt solenoids
What if I get a P0011?
P0011 is a diagnostic trouble code (DTC) that indicates a timing issue related to the "A" camshaft on bank 1 of the engine. The code description is "Intake Camshaft Position Timing - Over-Advanced (Bank 1)". This means that the intake camshaft on bank 1 is more advanced than the ECU expects it to be.
Possible causes for this code include:
1. Low engine oil level or dirty oil
2. Stretched or jumped timing chain
3. Faulty camshaft phaser or actuator
4. Camshaft position sensor issue
5. Sludge or debris in the oil passages
6. Wiring issues or damaged connectors related to the camshaft position sensor or actuator
In rare cases, a faulty ECU
