Do you have a pre lube system hookesd up? It is a good thing to have pressure in system before cranking. It eliminates dry starts which are the biggest cause of engine wear.

SOURCE: oil pressure gauge goes to 80 psi when the truck key is turned on

chances are your sending unit is not bad. These dashes have had alot of problems with stepper motors failing in the instrument cluster. does it go to zero when key is off? is it erratic? changes where it sits when running and when off? These are all problems within the cluster itself. It is not cheap to take this to the dealer. THey will want to replace the cluster. these clusters can be repaired for half the cost if you know where to go. Not sure yet what the rules are on here but i can repair these for about 325 verses over 600 from dealer and then reproggramming costs! One other note. Chevy has a recall on these! call you local dealer and ask what the criteria is for the recall. You may be able to get it repaired for free if you meet the time frame and mileage requirements.

SOURCE: Need to reset oil life

it depends........ if you have controls on the steering wheel or not. If you do, then go through the menu until you see OIL LIFE then hold in the reset button (looks like a backwards "L" with an arrow on it). Hold the reset button in until it reads OIL LIFE RESET or OIL LIFE 100%. If you don't have controls on the steering wheel, turn key on (engine off) and depress the gas pedal to the floor 3 times, now turn key off. crank engine up and see that it has reset, if not try it again.

Oil Pressure Gauge not working on my 2005 Yukon XL


Those gauges are electric now, check to see if the wire is on good. The sending unit can fail, cheap and easy once you find it, but requires a special socket, get that at the same time.

Why do i have high oil pressure on a 2006 yukon (80psi)


Not uncommon for oil pressure to read @ 80psi when oil is cold an thicker or a heavier weight oil, however, does it fluctuates or simply stays @ 80psi cold or at running temp? if so, its normal, if it stays there and doesn't move, that may a bad guage or sending unit. consider this and get back.

Yes, most likely it is a defective oil pressure sending unit. However, oil pressure is something you do not want to take chances with. Have it checked with a manual gauge to determine the problem as soon as possible to avoid possible major engine failure. I hope this helps.

Oil gauge reads 80psi what is the problem


Sounds like a faulty sending unit. Remove transducer (sending unit) and test pressure with external gauge. Hope this helps.

Changed oil in my jeep grand cherokee 1999 v6,and noticed the oil pressure gage is now setting at 80psi,and the filter is correct.


Not sure about your car, but alot of times the oil gauge sending unit is kinda close to the oil filter, and maybe during the oil change the wire connection was removed or damaged. Turn the key on and engine off ,and if the gauge reads 80psi then the sneding unit might be the problem

I just got my oil changed from firestone a couple days ago and now my oil gauge is at its max.. what can i do about this I have 2004 yukon


You probably just have a bad oil sending unit.Check the oil level first to make sure it is not over full.The sending unit is in the rear of the motor.Not easy to get to but if you look back there with a light you should be able to see it.Hope this helps.Good luck.

5.3 L Yukon XL oil pressure problems


Well first the GM oil pressure sending units are notorious for false readings, so what you must do is remove the oil pressure sending unit and plug in a test mechanical gage to verify the engine has acceptable oil pressure, after you are certain the pressure is ok replace the sending unit, it requires a special socket to remove it, the socket is about $5.00 USD. There is a deep socket and a shallow, so check the sending unit for the correct socket fit.
