Since ask to take these new test, then passing all 8, being an ASE Master Tech since the building said "Datsun" on the front of the building, I appreciate any tech who is will to not jump to conclusions and just start without testing first. You have my gratitude! In my day, we rebuild everything as the only part that came in a box from a distributor, carburetor, alternator or starter was new from the dealer. So using your scan-tools lab scope function to "SEE" the 5 volt or signal is the right way. Too many techs today start with a wheel borrow full of parts, then send back as defects when they don't fix the "Root" cause as you did.
Below the sender in the oil passage there's a screen that can be pulled out and cleaned. If this screen is plugged with debris you'll get weird p532 type codes with the new sender. Always pull the sender and pull out the screen and replace it clean. Saves you a come back later. There's a GM service bulletin on the issue.
I have a 2007 Suburban 5.3L - It has experienced oil consumption and oil pressure issues since 45,000 miles. The truck now has 260,000 miles after a motor rebuild at 126,000. Here is the best solution sequence I've come across after much research. Run the correct motor oil and a good quality filter, 5W30 and the best filter you can buy, I usually run a full synthetic and change every 6000 miles. Do not changes motor oil weights and use oil additives to solve this problem. 1) change the PCV valve cover to the new one, the original one is a flawed design, $120 and some labor ruclips.net/video/uC89I3j0e5Q/видео.html 1b) disable the AFM using a Range Technologies product. $200, no labor - plug it into the OBD port - this keeps your engine from switching into V4 mode using the AFM (active fuel management), it will stay in V8 mode all the time. It's a truck, keep it a V8, you might experience slightly lower MPG but your power will increase. AFM is one of the root causes of spark plug fouling and lifter issues. ruclips.net/video/HGdqaAoAR88/видео.html 2) change out the oil pressure sensor and screen if you experience sudden drop in oil pressure and get the idiot warning signal to stop your engine, with right tools and some tool dexterity you can change this yourself, beware some mechanics will do this job and eat up a lot of shop hours tearing the top off your motor to get to the part and screen. $80 parts, labor depends, DIY you'll have to buy the right tools, shop rate look at 1 - 2 hour minimum depending upon mechanic experience with this change.. ruclips.net/video/_LJW7UBlALY/видео.html 4) replace the o-ring on the oil pick up tube that inserts into the oil pump if you have a leak and your oil pressure gauge fluctuates, most likely the o ring has a crack and you are sucking air - $5 part but this is a labor intensive job and should be done by an mechanic that has access to a rack, tools and experience. ruclips.net/video/cofs-4Ex3VM/видео.html ruclips.net/video/51RusQeWZ1A/видео.html
You explained this sensor issue very well. I have the same issue with my 2009 Chevy Tahoe. I wanted to educate myself about the problem, so that I don't get ripped off. I have had to replace the fuel pump sensor on my Tahoe and the engine light is always on, no matter what I do. Thanks again!!
Good Video. I had a faulty oil pressure sensor reading at 0. I replaced the sensor and it read at 20 then went back down to 0. I also replaced the o-ring on the pickup tube. Dreading it’s the oil pump but I don’t hear any changed in the engine.
Just had my sensor AND filter replaced today. Make SURE they place a NEW filter when they replace the sensor. I had it done at dealership. My truck's been paid off for 5 years so I don't mind. Plus, the dealership works on Chevrolets 6 days a week, are used to replacing hard to get to parts like this, and they've got all the needed tools. I was in/out in an hour. Sometimes you pay for convenience.
If on the gauge sweep the oil pressure gauge would not have moved, that would set an engine code? Also did you replace or clean the oil pressure sensor filter right under it?
I have a 2007 Suburban 1500 5.3 L vortec which has a similar problem. It had trouble with oil pressure reading low quite some time ago, but it also had the AFM issue and I replaced the lifter a couple of times before I decided to buy the kit that replaces the cam and puts a new cover without the AFM stuff on it. When I finished it and got the PCM re-written, I was able to get the vehicle started and after awhile it ran well. I took it for a drive and it had several codes so I reset them and drove it some more. The codes did not return. Then I began to get P0521 error codes. The oil pressure is 40 psi at start up, revs to 80 psi or so and when hot it appears to be around 20 psi at idle. So I put a mechanical gauge on it which showed 36 psi but some air was in the line, too. The point was that the pressure was there just as the other gauge indicated. That made me decide that the sender must be the culprit and I replaced it. Alas, I had similar problems to get it out, but the worst came when the new one slipped out of my fingers and onto the cover plate under the intake manifold. I finally gave up trying to retrieve it and removed the intake manifold - it was stuck between the foam and the edge of the manifold. Now I got it all back together and started it - works like a champ. Took it for a drive - no error code. Fixed! Wrong! I took it for another spin a day later and sure enough, the error was back! I hear no clicking or engine noises that indicate low pressure, the engine gauges say the pressure is there, but the PCM says that the voltages are wrong. I checked the voltages between 2 and 3 and between the pins to ground. 0 volts all around with power off and 5 volts from 2 to ground and from 2 to 3 with power on. 1 and 3 to ground are both 0 volts as expected. Unless I got a bad sender unit, it should be ok. So what is it? If I pull the timing chain cover and replace the oil pump, nine chances out of ten there will be no improvement in oil pressure.
I’m having the same issue, oil pressure gauge reading zero. My issue is no engine light, no codes and no warning from the computer saying pressure is low. Ideas?
How is it going man,I have a ?? I have a chevy tahoe LS 2001,5.3 motor and its has zero oil pressure I put some BARS STOP LEAKS AND the nexs two mins BOOOM BELLS START GOING OFF AND NO PRESSURE,I got a new oil sensor,but still nothing,Any advice would be GRATEFULLY APPRECIATED,Thanks love the videos
Really Fantastic Video well done sir! Very Professional at what you done! I am having an issue with my 05 Tahoe 5.3 I was wondering what's your thought on it's running well going up and down the HWY and in the city but when I am at an a stop light the oil pressure drops and acts like it's going to die on me and it jerks when I start to take off from the light. but it's running fine otherwise.
Your video was very helpful today im getting a 06 later and im pretty sure its the sensor had chevys and seems after a fender bender or wreck in front end the guage and and sensor starts troubles. Thank you brother.
I replaced the oil pressure sensor and filter took me about 20 mins. I am no mechanic but I was determined to get that thing changed. My oil pressure now reads 20 psi, it won’t go any higher than that, it slightly goes up when I hit the gas for a few seconds but it stays under 20. What else could be wrong?
@@fixersautomotive4514 thanks, so this is what I did after that, I changed the oil, I used 10w-30 synthetic valvoline and changed the oil filter and also the air filter just because it was time to do it. After doing that my pressure was up to 40 again.
Btw I did that 2 weeks ago, after that a-lot of things have happened lol. My started dies and my wife was stranded in Houston, I changed the starter and the oil pressure was down to 0 again. I was upset. So I changed the oil again and nothing. And just when I was about to take it to the shop I thought, man I bet is that damn oil pressure filter that is clogged again. So I went to oreilly’s and bought one for $10. I switched it out and wallah, the pressure is up agaain. So this leads me to conclude that I still have a lot of junk in that engine that still clogging the filter.
Everybody’s going about getting to that sensor all wrong. If you reach straight down from the top of the engine at the back, it’s a direct line to the sensor 6 inch extension on a socket is plenty to get in there if you stick your phone straight back and take a picture of it you’ll see it nothing needs to be removed. It’s about a 15 minute procedure to remove it and replace it.
I am actually having this issues as well. But idk how long it's been like that honestly. It's not running different or knocking. Engine sounds great! I've only had the vehicle for 3wks.
erica captain this is a very common problem for Chevy V8 engine in any vehicle. Oil pressure sensors are usually easy to change out. If your engine doesn’t knock or runs just fine, that’s a good place to start. Good luck and thank you for your comment. Please share and subscribe to my channel.
Buy the socket. not just a deep socket. autozone sells the oil pressure sensor socket. also gonna need fuel line/ac line disconnect tool. its a chevy, nothing just slides off.
I have the exact same problem on my 13 Chevy suburban and my mechanic is saying his computer it's telling him it's electrical problem mind you we replaced the sensor a week ago and all was fine till yesterday when the reading stuck at 0
If the pin two no power supply 5volts,thats mean the problem is ECU from the engine? because as i know from the power box is 12 volts.and 5volts should be series' by resistor,and the resistor is inside the ECU.
My 2011 Tahoe ltz just started doing the same thing just happy it might be the switch vs the oil pump I think that’s really expensive I just got the truck and have to put money in it 😩😩😩
Was it the sensor? I have the same issue. Drove a bit this morning noticed zero pressure. I stopped and checked the oil just to make sure I had oil, lol. There were no obvious leaks. I didn't get a good measurement from the dip stick but I was just making sure it has oil. Got home, parked, let it cool & settle and oil level is good. Is it possibly pumping oil but indicating there's no pressure? I purchased the sensor and plan on replacing it tomorrow. I'm just worried it's something worse and by worse I mean expensive. 2009 Tahoe LTZ 5.3 flex 4x4 (Edit to add: my check engine light is on and my oil pressure gauge does not even move but I do not get a warning on the driver information read out, no "low oil pressure/ stop vehicle". Does that mean anything?)
My 2012 Silverado oil gauge would drop to 0 after running down the road for 5 min. Display said shut off the engine. After a few min shut off and restart the oil gauge was fine 40psi. I replaced the sensor and screen. During removal I could not ID the clip holding the wire connector to the sensor. I just pulled the connector up and removed the sensor and screen. I saw a method on RUclips to thread a screw into the filter that worked fine. I replaced the sensor with OEMAC/Delco parts. Oil pressure gauge came right up to 50psi. I did an oil change and filter. Next time I drove the truck it happened again! Pulled over shut it off. Restarted immediately and had full oil pressure. I’m thinking the connector warms up and gets loose due to no hold down clip? Any thoughts.
Marty Van Haren higher mileage vortec engines don’t like synthetic motor oil. At least in my opinion and what I’ve seen. Also it seems to sound like you might have a bad O-ring from the oil pump pick up to the oil pump, that is a known issue with low to no oil pressure problems. If your truck is not a four-wheel-drive it’s pretty simple to drop the oil pan and change the oil pump pick up tube oring, I hope this helps keep me informed.
What if I change the o ring the fpm pcm throttle body and throttle body sensor oil pressure sensor and light still came back I checked the compression and it 40
Hey bro whats up i have p0521 it reads about 14psi at idle and at 3k rpms at 30psi I replaced the oil pressure sensor and i keep getting that code very fast so I started checking and noticed that engine off key on i have 2.9 psi and if I unplug the sensor it drops to 0 psi is it normal to be at 2.9 psi when engine is off and it’s probably my oil pump going bad?
I would replace the oil pressure sensor w/ a factory one first. Just unplug the sensor off the old one, open the box and plug it into the new sensor and see what it reads.
I did every thing which is mentioned in this video but still no luck. Still its showing 128 psi oil pressure weather the engine is running or stopped. Can enyone help me with this plz. Really in big trouble
@@fixersautomotive4514 i did the guage sweep and its not working. But it is saying in the dash that engine oil pressure low turn off the vehicle. My question is if the guage it self not working will it display this message or not. I bought orignal sensor from dealer. But same problem. Reallllly need help. By the way, thanks for replying ☺️. U r awesome
Abdullah Awan yes if the sensor is bad it will say that message. If you can check the oil pressure mechanically w/ a oil pressure gauge just to make sure the oil pressure for the motor is fine and not low. The stepper motor in the dash is probably bad, that’s what a gauge sweep is for to test all the gauges.
So now that i installed the new sensor, is unplugging the battery and plugging it back one way to clear the code or do i leave the check engine light running, drive the car and wait to see if turns off on its own?
Fixers Automotive oh ok, so then my next question is by clearing the code then are we telling the pcm to not ever show it again or, isit something that if that sensor ever goes bad again if that's the case, it will bring the code back?
937anme by clearing the check engine light code your telling the pcm that the problem is fixed and the pcm will run a self test when you start it up and if it was fixed correctly it will pass the test and the light will stay off. Also what you can do is removed both battery cables, touch both cable ends together for 10mins. This will discharge all the back up power in the pcm and it should reset, doesn’t happen all the time but worth a shot. Good luck.
Want to see if you can help me I have a 2007 avalanche a change everything sensor pick Up tube ring whale and filter a couple times I could not get the wall pressure to stay up when I am I that idle it goes down to 0 but when I hit the gas they do rise
I had the same issue, I also got the oil pump switched ,pick up tube seal , sensor, filter , oil change , Mechanic told me that i need a new motor at 148,152miles
Me too. Changed the sending unit, oil pump, pickup tube o-ring, and pan gasket....I have discovered that the gauge in the instrument cluster (in the dash) is bad - BUT in reality I have perfect oil pressure. I jumpered out the sender unit wires gray and tan, and the gauge went to zero... Hook a mechanical gauge up to the engine - and this will tell you the actual oil pressure.
I’m having a similar issue. My gauge says I have about 20 but the Informations button (dash) says my oil life is 100% Check the dipstick and it is also kindve dry. Should I get a oil change and get the sensor changed ?
Arslan Tariq, the oil pressure gauge on the dash is different then the oil life percentage. The gauge on the dash should read about 20psi at idle. If the dip stick is dry get a oil change and make sure the shop reset the oil life percent. If you have a 5.3L Engine the oil capacity is 6qts U.S. Hope this helps. Thx and good luck. 👍🏼
I had a mechanic check my 2005 tahoe 5.3 it was doing the same thing the gage was stuck at zero no movement at all n it said oil pressure low. So what he did was remove the sender unit or sensor. So after it was removed he put his finger covering the hole where the sensor was. And he had me turn on the engine. He said theres no pressure coming out so he said i have a bad oil pump.. Is this possible bro can you really check like that.. Now my Tahoe never makes a noise there is new engine oil.. Please bro i need help.. Now the mechanic guy didnt have no computer device to check like you did.. The reason i had him come over was because ive heard its dangerous to drive your vehicle on low oil pressure.. Nearest shop is a 15 min drive.
Juan Macias so the next thing you would have to do is look in the hole where the oil pressure sensor there is a oil screen that gets clogged up and won’t allow oil to circulate. Most of the time it’s easier to remove the intake manifold in order to get the oil screen. The other quick check is to install a mechanical oil pressure gauge into the sensor hole and start the engine and see if you have oil pressure on the mechanical gauge. You can normally rent the gauge tool from your local Autozone or parts house. Hope this helps and let me know. Thank you.
Juan Macias ya man, don’t start the truck for longer then like 30 seconds w/ no oil pressure. It’s very rare that a oil pump just dies w/ no warnings. Where there any other problems w/ the truck before the no oil pressure dropped?
@@fixersautomotive4514 i notice for a while that whenever ill step on the gas the oil gage will go up then it will go down when ill let go off the gas pedal.. But that happend for years everytime ill step on the gas n yes i have a heavy foot
So I know this doesn't have a ton to do with this video but was hoping someone could point me in the right direction. Upon starting my engine the oil pressure is just above 40 after it warms up and is driven a bit it slowly drops down eventually to 0 and tells me to shut off engine. I have replaced the sending unit and screen. This seemed to fix the problem for a couple weeks. I then changed the O-ring on the pickup tube last night. Refilled with fresh 5w-30 synthetic oil and did a test drive this morning and still having the same problem. the engine never sounds like it isn't getting enough oil to any part. If anyone has another direction to head I'd appreciate any ideas. Thank you.
If I was you, I would install a mechanical gauge w/ a hose that’s long enough to read w/ the hood closed. Install the gauge in the same hole as the oil pressure sensor. Take it for a drive and see if you lose oil pressure. If the oil pressure drops again. Then it’s your oil pump. Worse case scenario if the oil pump doesn’t fix it then it’s inside the block. Maybe main bearing wearing out. How many miles you have ? Also maybe use a thicker base oil 20w50. Hope that helps.
@@fixersautomotive4514 it has 145k miles. I'll see if I can find a gauge to get that checked out. the oil pump would defiantly be better than anything in the engine. thanks for the reply
@@ryno856 everything went south. Put in a new engine. Something bounced around under the head. From what I could tell this is the first sign of the end
@@AlacraneroRevel i just had everything replaced on my 07 avalanche, 148,152 miles Sensor, filter , oil pump, oil change , and nothing ,. Then mechanuc calls me and says that i need a new motor , good thing i still have the warranty...
Any Idea of what this sound may be? ruclips.net/video/lnWUaX7Kg0E/видео.html I went to work and realized my oil light was on as I was on the highway, as soon as I pulled up to work, the engine shut off and wouldn't restart. I went and got oil and it started, but now makes this sound. easy fix? or a new engine? any recommendations?
That sounds like a collapse lifter making the ticking noise. You might have to remove the valve covers to see if there are any loose rocker arms and pushrods.
Chevy Tahoe thank you for the comment, I’m sorry video wasn’t up to your expectations. I will try to be more thorough w/ my new videos. Have a great day.
Fixers Automotive I replaced mine it was a pain in the ass but your video showed no sensor you replaced it was some machine testing the truck but we know it’s bad that’s why I needed a video on where it was and how too free it

More then likely it’s the sensor. 95% of the time it’s just the sensor. Good luck.
Was it the sensor?
I have the same issue. Drove a bit this morning noticed zero pressure. I stopped and checked the oil just to make sure I had oil, lol. There were no obvious leaks. I didn't get a good measurement from the dip stick but I was just making sure it has oil.
Got home, parked, let it cool & settle and oil level is good. Is it possibly pumping oil but indicating there's no pressure? I purchased the sensor and plan on replacing it tomorrow. I'm just worried it's something worse and by worse I mean expensive.
2009 Tahoe LTZ 5.3 flex 4x4
(Edit to add: my check engine light is on and my oil pressure gauge does not even move but I do not get a warning on the driver information read out, no "low oil pressure/ stop vehicle". Does that mean anything?)
Awesome video 👌
I need a mechanic like you here where are you located. Great job
Thank you for the nice comment. I’m in Tucson, Az.
Great video dude. Thank you.
Thx man for the nice comment.
I just finished replacing this sensor on my 2008 Yukon.. it was a BITCH! seems like there may be less room with the 6.2 engine???
Lyle socket /6” wobble extension:flexible adapter easy life !
MPLS Car Sales thank you for the input. It’s alway nice to hear of different ways and techniques to do the job.
My 2012 Silverado oil gauge would drop to 0 after running down the road for 5 min. Display said shut off the engine. After a few min shut off and restart the oil gauge was fine 40psi.
I replaced the sensor and screen. During removal I could not ID the clip holding the wire connector to the sensor. I just pulled the connector up and removed the sensor and screen. I saw a method on RUclips to thread a screw into the filter that worked fine. I replaced the sensor with OEMAC/Delco parts.
Oil pressure gauge came right up to 50psi.
I did an oil change and filter.
Next time I drove the truck it happened again! Pulled over shut it off. Restarted immediately and had full oil pressure.
I’m thinking the connector warms up and gets loose due to no hold down clip?
Any thoughts.
Marty Van Haren higher mileage vortec engines don’t like synthetic motor oil. At least in my opinion and what I’ve seen. Also it seems to sound like you might have a bad O-ring from the oil pump pick up to the oil pump, that is a known issue with low to no oil pressure problems. If your truck is not a four-wheel-drive it’s pretty simple to drop the oil pan and change the oil pump pick up tube oring, I hope this helps keep me informed.
What if I change the o ring the fpm pcm throttle body and throttle body sensor oil pressure sensor and light still came back I checked the compression and it 40
Hey bro whats up i have p0521 it reads about 14psi at idle and at 3k rpms at 30psi I replaced the oil pressure sensor and i keep getting that code very fast so I started checking and noticed that engine off key on i have 2.9 psi and if I unplug the sensor it drops to 0 psi is it normal to be at 2.9 psi when engine is off and it’s probably my oil pump going bad?
I would replace the oil pressure sensor w/ a factory one first. Just unplug the sensor off the old one, open the box and plug it into the new sensor and see what it reads.
In the video I didn’t show replace the little screen under the sensor. Make sure to change that also.
Very helpful.
Thanks
I did every thing which is mentioned in this video but still no luck. Still its showing 128 psi oil pressure weather the engine is running or stopped. Can enyone help me with this plz. Really in big trouble
Abdullah Awan hello, are you able to do a gauge sweep? The dash gauge itself might be bad. Maybe try a different brand of sensor.
@@fixersautomotive4514 i did the guage sweep and its not working. But it is saying in the dash that engine oil pressure low turn off the vehicle. My question is if the guage it self not working will it display this message or not. I bought orignal sensor from dealer. But same problem. Reallllly need help. By the way, thanks for replying ☺️. U r awesome
Abdullah Awan yes if the sensor is bad it will say that message. If you can check the oil pressure mechanically w/ a oil pressure gauge just to make sure the oil pressure for the motor is fine and not low. The stepper motor in the dash is probably bad, that’s what a gauge sweep is for to test all the gauges.
So now that i installed the new sensor, is unplugging the battery and plugging it back one way to clear the code or do i leave the check engine light running, drive the car and wait to see if turns off on its own?
937anme hello. You will need to have a scanner or code reader to reset the pcm. The code will not turn off by itself.
Fixers Automotive oh ok, so then my next question is by clearing the code then are we telling the pcm to not ever show it again or, isit something that if that sensor ever goes bad again if that's the case, it will bring the code back?
937anme by clearing the check engine light code your telling the pcm that the problem is fixed and the pcm will run a self test when you start it up and if it was fixed correctly it will pass the test and the light will stay off. Also what you can do is removed both battery cables, touch both cable ends together for 10mins. This will discharge all the back up power in the pcm and it should reset, doesn’t happen all the time but worth a shot. Good luck.
Fixers Automotive thanks, will do.
Awesome job brother.
Nice job bro
Damn Engineers!
Where are you located
Justo lo que necesito. Thanks.
Want to see if you can help me I have a 2007 avalanche a change everything sensor pick Up tube ring whale and filter a couple times I could not get the wall pressure to stay up when I am I that idle it goes down to 0 but when I hit the gas they do rise
I had the same issue,
I also got the oil pump switched ,pick up tube seal , sensor, filter , oil change ,
Mechanic told me that i need a new motor at 148,152miles
Me too. Changed the sending unit, oil pump, pickup tube o-ring, and pan gasket....I have discovered that the gauge in the instrument cluster (in the dash) is bad - BUT in reality I have perfect oil pressure. I jumpered out the sender unit wires gray and tan, and the gauge went to zero... Hook a mechanical gauge up to the engine - and this will tell you the actual oil pressure.
Good video. I remove that sensor with. Out. Removing. The intake
Had that problem with that shield, I just cut it off.
What's the best oil to run through their
Is it the same for a dodge journey because that is the same issue I am having..
patrick helm, it’s the same testing process. As long as you test it the same way.
I’m having a similar issue. My gauge says I have about 20 but the Informations button (dash) says my oil life is 100%
Check the dipstick and it is also kindve dry. Should I get a oil change and get the sensor changed ?
Arslan Tariq, the oil pressure gauge on the dash is different then the oil life percentage. The gauge on the dash should read about 20psi at idle. If the dip stick is dry get a oil change and make sure the shop reset the oil life percent. If you have a 5.3L Engine the oil capacity is 6qts U.S. Hope this helps. Thx and good luck. 👍🏼
@@fixersautomotive4514 where is your shop located?
Hilda Ochoa I’m in Tucson. Az.
@@fixersautomotive4514 aww ok thank you I was hoping you were in San Diego Ca.. I'm having the same problem with my tahoe
Hilda Ochoa good luck. Let me know if it’s gets fixed. San Deigo is my second home.
I had a mechanic check my 2005 tahoe 5.3 it was doing the same thing the gage was stuck at zero no movement at all n it said oil pressure low. So what he did was remove the sender unit or sensor. So after it was removed he put his finger covering the hole where the sensor was. And he had me turn on the engine. He said theres no pressure coming out so he said i have a bad oil pump.. Is this possible bro can you really check like that.. Now my Tahoe never makes a noise there is new engine oil.. Please bro i need help.. Now the mechanic guy didnt have no computer device to check like you did.. The reason i had him come over was because ive heard its dangerous to drive your vehicle on low oil pressure.. Nearest shop is a 15 min drive.
Juan Macias so the next thing you would have to do is look in the hole where the oil pressure sensor there is a oil screen that gets clogged up and won’t allow oil to circulate. Most of the time it’s easier to remove the intake manifold in order to get the oil screen. The other quick check is to install a mechanical oil pressure gauge into the sensor hole and start the engine and see if you have oil pressure on the mechanical gauge. You can normally rent the gauge tool from your local Autozone or parts house. Hope this helps and let me know. Thank you.
@@fixersautomotive4514 mannn bro i really appreciate your help ill do that today..
@@fixersautomotive4514 I turned on my truck to just check the gage and it stared making a lil ticking noise bro.. I turned it off right away
Juan Macias ya man, don’t start the truck for longer then like 30 seconds w/ no oil pressure. It’s very rare that a oil pump just dies w/ no warnings. Where there any other problems w/ the truck before the no oil pressure dropped?
@@fixersautomotive4514 i notice for a while that whenever ill step on the gas the oil gage will go up then it will go down when ill let go off the gas pedal.. But that happend for years everytime ill step on the gas n yes i have a heavy foot
So I know this doesn't have a ton to do with this video but was hoping someone could point me in the right direction. Upon starting my engine the oil pressure is just above 40 after it warms up and is driven a bit it slowly drops down eventually to 0 and tells me to shut off engine. I have replaced the sending unit and screen. This seemed to fix the problem for a couple weeks. I then changed the O-ring on the pickup tube last night. Refilled with fresh 5w-30 synthetic oil and did a test drive this morning and still having the same problem. the engine never sounds like it isn't getting enough oil to any part. If anyone has another direction to head I'd appreciate any ideas. Thank you.
If I was you, I would install a mechanical gauge w/ a hose that’s long enough to read w/ the hood closed. Install the gauge in the same hole as the oil pressure sensor. Take it for a drive and see if you lose oil pressure. If the oil pressure drops again. Then it’s your oil pump. Worse case scenario if the oil pump doesn’t fix it then it’s inside the block. Maybe main bearing wearing out. How many miles you have ? Also maybe use a thicker base oil 20w50. Hope that helps.
@@fixersautomotive4514 it has 145k miles. I'll see if I can find a gauge to get that checked out. the oil pump would defiantly be better than anything in the engine. thanks for the reply
You figure it out? Same with my 12
@@ryno856 everything went south. Put in a new engine. Something bounced around under the head. From what I could tell this is the first sign of the end
my truck is doing exact same thing
Just changed the oil pressure sensor and filter. Code P0521 and P0171 came on the dash. Mecanic says that oil pump has to be changed. Any suggestions?
Geovanni Dominguez same vehicle?
P0171 is a lean code, nothing to do w/ oil pressure or the code.
No is 2011 chevrolet silverado 5.3
The lean code came up because the lifter is not getting enough oil. Thats why my mecanic told me that the pump needs to be replaced.
@@AlacraneroRevel i just had everything replaced on my 07 avalanche, 148,152 miles
Sensor, filter , oil pump, oil change , and nothing ,.
Then mechanuc calls me and says that i need a new motor , good thing i still have the warranty...
Thank you!
Kenny Lowe thank you the nice comment, stay safe and heathy during theses times.
You didn't show the gauge after you were done
I changed the oil and filter and the pressure came right back
One of the lucky ones. Hope that’s all it was! 👍🏼
what is a normal oil pressure for that 5.3
40 at idle
I cut off a piece of the plastic cover it make it easy 🙂
Any Idea of what this sound may be?
ruclips.net/video/lnWUaX7Kg0E/видео.html
I went to work and realized my oil light was on as I was on the highway, as soon as I pulled up to work, the engine shut off and wouldn't restart. I went and got oil and it started, but now makes this sound. easy fix? or a new engine? any recommendations?
That sounds like a collapse lifter making the ticking noise. You might have to remove the valve covers to see if there are any loose rocker arms and pushrods.
What's ur location?
Tucson.Az
Oh wow ok
Where you from?
I'm from mesquite texas ...its hard to find a loyal mechanic now n days
This video sucks too I watched the whole 13 min video and not one time was the sensor showed on the engine, not helpful one bit 🤦♂️
Chevy Tahoe thank you for the comment, I’m sorry video wasn’t up to your expectations. I will try to be more thorough w/ my new videos. Have a great day.
Fixers Automotive I replaced mine it was a pain in the ass but your video showed no sensor you replaced it was some machine testing the truck but we know it’s bad that’s why I needed a video on where it was and how too free it
It’s a POS flaw, lmao
