Chevy Truck No Oil Pressure - P0523

[@eldoradony]

Love customers like that. Every warning light is on, brakes are grinding, mismatched tires are unsafe and battery is bad. They bring it in because the power plug is out and they can't charge their cellphone!

[@SouthMainAuto]

I literally laughed out loud haha... Glad to know it's not only happening here haha

Lmao!!!!

[@daveblane6442]

Yeah how did they know they could drive it?

[@thetinpin]

First fix the A/C and the power port, THEN look into the shaking, the white exhaust cloud, and the flashing yellow motor light thing, ok?

[@johnreid859]

Getting ready to do this job, thanks for the video Eric! Chevy dealer quoted $624 out the door for this job. I finished the job in about an hour for the cost of the parts. Thanks again.

[@conrado5910]

John Reid. Good job saved alot of money

[@nephetula]

I would NEVER go to that dealer again! (They are ripoff artists.)

[@GregSr]

Wow! This repair is very similar to what I did on my 2003 Corvette. Same symptoms too. The oil pressure switch went to full scale which was 80 on the analog gage and 130 on the digital readout. One difference: my Vette did not set any codes. The oil pressure switch is right where you showed it - but one big difference. The back of the engine sits under the bottom of the windshield. It took me two hours to complete the job. The local repair shop wanted $250 plus parts. I said no thanks and did it myself.

[@openyourmind5534]

Funny took me 10 min with the right tools and didnt have to remove anything

[@michaelmoreno4939]

Going through this now. This video should help to avoid doing it the hard way. My shop wanted $475 for labor.

[@peterdragon9630]

I have a '96 Silverado 454/7400 gauge does the same thing- shows zero at idle, then jumps to 50-60 when revved, no engine noise, would have blown by now, been over a year, pretty much assumed it was the sender like you found here, will get around to it sometime- it's a bit of a beast to get to and don't have that cool ratchet you have. I like that creeper thing too- never knew they existed. I learned something. Thanks.

[@stewarttwins]

This was awesome! I wish that you lived in WPB!!! I would bring my car to you every time!

[@KevinJohnson-fx6wq]

When I first got my '07 Mitsubishi Galant the guy I bought it from had some experience and told me oil sensors would go in these cars. About a year later I was driving up to Rochester and the oil light came on, so I put some oil in without checking the oil. Yeah, what can I say, when I got back and checked the oil it was overfilled. It took me a couple days and then I remembered being told about the light and ordered a new sensor. Yup, mine was in a weird spot behind the engine too, and think may have needed some special tool and since I had an inspection due I just had my mechanic replace the sensor. Well worth the $30 and I did siphon some oil out too. Thanks for sharing.

ASE stands for *ask somebody else* 'cause they dont know.

[@consaka1]

+byrysh Lol. I have seen some pretty smart ASE certified mechanics. I have also seen some that were totally clueless as to any of the physics behind what makes anything happen on a car or engine. My first boss was not ASE certified and he was a bloody genius with truck engines and knew his way around a welder like nobodies business. He was an expert in many things and could pass the day telling real life stories to emphasize his point. In fact he could do that so well the day could end without a danged thing getting done. lol John Nesbitt. A great boss and genius in many things. No joke when I say ASE mechanics routinely called him with tricky problems.

[@byrysh]

consaka1 I was ASE certified in 90's lol I was makin a joke. Ive seen some supersmart ones too as well as some that were realy... well not so much.

[@kencaldwell1399]

ASE is really about how well you could take a test. I used to be an ASE certifies Master Truck Technician. I was a pretty fair mechanic in the fleet world, but there were guys in other fields that were so much better than I was. They may or may not have been certified.

[@mechanictaft4848]

[@int53185]

No thumbs down. Pretty impressive, Eric O.

[@swissking2002]

Well guess what, it seem like it was the oil pump. I change out a lot of thing and this was a lot of work. I end up also changing the oil pan gasket, filter valve that located on the oil pan, timing chain cover since I took it off, also the oil pressure sensor and small filter. I used a proformance oil pump milling 365. Well everything is working great and oil pressure is back to 40. not to mention the oil pan was dirty and had some sludge. My truck had only 96,346 miles. I don't know why this happen, Well I'm happy to get her back on the streets. Thanks for help

[@mattbartholomew5707]

All the warning light bulbs are working atleast it has that going for it. Remember when my oil warning light came on with my last car on the highway within the minute it took me to find a safe spot to stop the engine was a gonner. Served me well though with a total of 213,000 miles on the clock to be destroyed by a o-ring blocking the oil pick up.

[@SouthMainAuto]

All good things come to an end my friend...

[@ronniecardy]

Had mine replaced also along with a leaking heater hose. Cheap plastic hose fitting on the heater core went bad

[@SteveRobReviews]

Well done - at least GM puts a real oil pressure reading gauge on their truck. On my Ford they cheeped out, it's just a on/off switch shown in a gauge needle that swings to 3/4 and off. Hey Eric I don't have any ASE accreditation either, how did we ever survive this long :) I replaced the intake gaskets on my 6 liter 2 months ago and also replaced the knock sensors and harness , not the oil pressure switch. For sure after watching your vid it's going to crap out. LOL

The engines in these trucks are famous for losing oil pressure, though. The O ring in the pump pickup is known to fail, causing it to suck in air.

When no.6 coil went bad on my '08 Cad DTS it set off a number of false messages including "Service Stabilitrak/Traction Control". A new coil and all warnings gone. I can see a lot of folks helping pay for the fancy dealership remodel project by getting charged for parts they didn't need or that were never installed.

[@jaywebb0113]

+matt zehentner when your coil went bad it was causing a misfire when these engines detect a misfire the traction control and stability control will be disabled and those lights will show on dash as something is wrong with those systems. I see it every day at work.

My neighbors 2007 1500 5.3 lost oil pressure the other day. Truck dipstick showed down a quart. I topped off and started, gauge went to 40 at 1800 RPM . I can keep at 1800-2000 and it will stay at 40 ish for about 3 minutes then slowly drop to the warnings coming on then to zero.. To me this sounds like once oil get warm this sounds more like pump area problem more than a sensor. Any thoughts before I dive in?? Tom

First time viewer here! I just did this on a 2003 Chevy Tahoe.. what a pain.. Looked like my vehicle had way more stuff right back there where I needed to get to than several I have seen here on KZbin. That job literally took me 6 hours to do! 6 hours of laying on top of the engine trying to not only get my hand back in there, but replace the part! Used a little shop mirror and multiple lights... important thing is I got it done, but what a pain! I don't do this for a living, it was my wifes vehicle.. Im usually working on my 1994 Ford F150, so was a change of pace for me and a relatively bad experience. LOL!! I do have my own KZbin channel as well if anyone is interested, primarily about the restoration and other things on my F150 Pickup, but its not strictly a Ford only channel or anything, although that's mostly whats on there now. Hope you don't mind me plugging my channel here. At any rate, nice video and Im subscribing. I am very interested in that topside creeper that you have!! I have a 6 inch lift with 35" tires on my truck and something like that may come in very handy!! Im 6'2" tall or so, but still have trouble reaching stuff. Do you have any info on that creeper? Im going to google it and see what I can find as well. Keep up the good work! Going to be a horrible rotten hot and humid day here in Central Iowa, so may just stay kicked back in my recliner, nice and cool in the A/C and watch KZbin vids all afternoon. LOL
