Chevy GMC No Oil Pressure Gauge Reading

[@carl651987]

Wait till the Engine is cool. Lift the vacuum hose out of the way and reach behind and you will feel the wiring. Pull the plug. Use a 1 1/16 thin walled socket and a short extension. The sender will come out fairly easy. Make sure you replace the screen. I was able to do this easy without removing anything at all.

[@pain779]

Just wanted to say thank you for youre video very informative and straight to the point people like you help the working class folks that can't afford a shop .keep up the good work there are so many people that rely on you in there time of need . Mine quit today at 3 am I had pulled over and removed the oil fill cap and verified oil being pumped up closed it up and drove to work and home before changing it took me about 25 30 minutes it is very difficult to get to but I did not unhook any lines just removed the plastic cover and used a small tbi unit hold down bolt off a 90s Chevy to get the screen out it was plugged solid .

FYI. I did this with success on a 2010 suburban.

[@ILBIS123]

The Oil Pressure Low Message Is a GM defect on the oil pump pressure relieve valve plunger that gets stucked. They should make a RECALL of all vehicles that have this problem, It is very costly to replace the oil pump for something so small and simple. Envoys, Bravadas, Trailblazers and a lot of other vehicles. There should be a Class Action against GM for this. The problem is that when the valve is defective the computer incorrectly senses Low Pressure. That’s why when you step on the gas, the low pressure message disappears! In other words…is just a momentarily lie from the valve that makes the computer think that It has no oil and your car stalls trying to protect itself. This is how I solve it “momentarily” after I did all this… Changed the oil sensor. Flush the engine with Kerosene Replaced the engine pickup tube. Clean the throttle body (was dirty) After all that, I was about to give up and sell my Envoy, but I finally found a video where it was explaining the oil pressure relieve valve defect What I did, was to change my engine oil to 40W and use LUCAS oil treatment And Voila! The engine oil pressure went up and the low pressure message has disappeared. (up to now..knock on wood). I wish you all luck. kzbin.info/www/bejne/f52Yd5KHm616jJY

Good work. Always nice not having to pull the intake and losing half the bolts. This way you can just drop a few sockets down the back of the engine by the time you're done.

What a hassle just to get to an oil filter screen.

[@fishnpitstaknnames4699]

Dont use ac delco oil filters. The oil pressure in my z71 dropped out and I thought I had a real issue, just needed an oil change. I switched to mobile 1 filter and it had been awesome. 10 bucks but better than ac delco.

good day sir, from the philippines. i would like to know if there is a problem with my oil sensor if it slightly fluctuates during idle? should i worry about it?

No chevrolet is gonna fluctuate as the oil pressure changes I wouldn't worry about it

Does anyone know if a faulty oil sensor will cause a know start condition

[@shanestout3543]

You did not mention the issues the 5.3 has with the oil pump pickup tube o-ring.. where pressure starts normal and as it gets warmer it continuously declines to zero or almost zero... I have found this as a professional in shop mechanic to be more common than anything when it comes to abnormally low oil pressure readings..

[@Gendo3s2k]

I'm not really seeing the exact problem that I'm having anywhere. I have an 06 silverado with 4.8. At idle, it shows 80psi, under load, it shows 0psi. There doesn't seem to be anything other than 80 or 0

They should make a relocate kit. Maybe thread a high pressure hose in the back and locate the sensor on the firewall.

I have a 2003 Chevy Silverado 5.3 and my oil pressure went all the way up to 80 so I switched the oil pressure sensor and it was working fine but two weeks later my oil pressure went down to 0 and I got the low oil pressure sign.

[@fish4fun354]

1:07 You should mentioned the screen is not on the cateyes.

[@billbright1755]

Just imagine had the unit been located at an accessible area of the block possibly even a space near oil filter. A five minute change out rather than all that procedure and special tools with possible dropping of small parts and tools. Always disappearing into the most inaccessible crevice on vehicle. Wire connectors with tricks for separation hidden behind useless unremovable plastic shrouds as far back in engine compartment as possible. Replacement part through defect let’s you have the fun again in a few months after vehicle leaves you stranded in below zero blizzard because of false readings to computer. Boeing had an analogous situation with nose mounted angle of attack sensor that would override inputs. Trying to gain altitude for terrain avoidance while computer say dive at precipitous descent. Kind of annoying.

I'd get a vehicle towed if it had this problem because if the warning is real then your engine can be destroyed within seconds after getting the warning. Unless you have the tools to diagnose or fix it right then and there, but definitely don't drive it and tempt fate. Very expensive gamble.

how long can you drive the truck before fixing this problem

If its actual low oil pressure it will probably destroy your engine and a few minutes of driving. If it has pressure it will run for years like this but I wouldn't because you wont know if a low pressure problem develops and then you have some real problems on your hands.

So my oil pressure switch threw the code but my truck doesnt have the gauge. I replaced the switch but i cant tell if i still have the problem. I have a scan tool but it wont show oil pressure. Should my ecu read oil pressure on my 2011 5.3 silverado. Also does anybody k ow if the code would quickly pop up again after i cleared the code?

[@noahkb80]

Maybe someone can give me a little guidance on where to go next. So my sensor on my 08 silverado was out for a while. Too log. Just read 0 always. Could clear the code with my OBDII device, and it would sit maxed at 80 until next time I started truck. And it would clickity clack all over the place. Yes I drove it like that. Dont judge me, had no choice. Divorce, custody fight, man's gotta work. Never burnt any oil and sometimes the noise goes away, sometimes not. So finally replaced the sensor and filter and now the guage moves with my rpms. If I stop moving it falls all the way to zero and starts warning to shut off engine. Still not losing any oil and it doesn't make any noise. Smooth and quiet . Now at about day 3 with new sensor, the guage still goes up and down. And after maybe 20 minutes of driving, the clicking comes back , although not near as loud, and still not losing any oil. Initially I had a P0523 code. Now its a P0521. Which way should I go next? Pick up tube? I'm sure I need pressure test. Help me out here folks

[@reggiewilliams976]

You don’t have to remove all that just to get to the sensor... Just remove the comer and reach behind there and take it out... You can’t really see it, it’s mainly feeling your way around it... Good video but unnecessary removal of hoses... I just did this job today on my 07 GMC Sierra 1500

[@kenman1717]

Another great tip. Something I've noticed that really contributes to this, at least in my experience, going to long on the oil changes. have noticed this a lot when people run synthetic oil, they go way to long, the oil gets to thin and dirty and it plugs up those screens and the sensor. But something else I've noticed, on the engine with the active fuel management that have the oil consumption problems seem to be worse for this.

[@fieldsofomagh]

[@kenman1717]

Totally agree. This guy keeps the oil super clean and it apoears to be strictly on the electrical side. 125K is actually a lot of miles up here.

[@kenman1717]

warriorpluto if you have good oil pressure, not using oil, no noise and do your oil changes when you should, I wouldn't worry to much. and something to keep in mind, warm your truck up for about 10 mins or so before draining the oil on an oil change it really helps cut down on sludge build up. have pulled engines apart with 300000kms on them and the lifter valley had over an inch of hard caked on sludge and it was do to many cold oil changes.

I have a 2003 Express van with the 5.3 engine. Oil pressure gauge is pegged at 80 psi all the time, never changes. But now the oil light is coming on when I start it and stays on for 2-3 minutes, then goes out. Does that while gauge reads 80 psi, and does this with engine cold start or hot start.

Probably because the sensor is giving an erroneous reading to the PCM and triggering the message.
