a general minimum oil pressure specification is 10psi for every 1000rpm engine speed.

500rpms does seem low for the idle speed. does your vehicle have a throttle cable or drive by wire throttle actuator (tac)?

if it has tac a dtc would set if the idle speed is more than 100rpm off the commanded speed. Any dtc's set?

 

I had a keyless remote for my 2005 Chevy Uplander. We went on vacation and it got broke. I bought a new one and don't have the money to pay a dealer to program it for me. Is there anyway someone can help me program this thing to my van. I can't find instructions to do it. Thank you so much for any help you can give.

 

post this question as a new thread and you might get some replies.

 

I had a similar issue on my 2007 Tahoe LTZ with the 5.3L V8. What I did was replace the oil pressure sensor/switch (on upper rear of engine block) and then also clean out the the little orange-colored cylindrical mesh filter directly under it. It is called the "intake oil filter" and it was clogged with oily gunk (from 125,000 miles) so I blasted it with carb cleaner and some compressed air. This now gaurantees that the sensor is getting a clean measurement of pressure. Note, I took the intake off to get at this area because it buried back near the firewall and you will never access the filter without removing everything in the way. I put new intake gaskets on while I was there but if you were in a pinch you could clean and re-use the exiting ones. My oil pressure is now perfectly restored at idle (40-ish).
Thanks,
John

 

yep good post.

If you ever have to have the oil pan removed get the afm oil pressure valve shield installed. This will prevent any oil consumption issues.

The switch and filter can be replaced on engine even though it says to remove the intake.

The 2005 non afm engine may not have the filter but will have the sensor/switch.

 

Thank You - I will give that a try.
