SOURCE: '04 GMC Yukon Denali Check Engine Light

Did u put in fuel shortly before the light came on? I own 2 service centers & the most common situation with "Check Engine" lights are because the fuel cap wasn't re-installed or not tightened. When you refuel make sure it "clicks" when putting back on. We don't charge for a "Code Reading" but a dealer will, don't go there. Go, like the others suggested. If it is the fuel cap & you re-install it correctly, the light will go off after a short drive. Good Luck. PS-Don't panic when the "Check Engine" light comes on unless it blinks, if that happens don't drive. PSS-RE: Murray's, Auto-Zone.......If it's a "Code" (the reader will give a #) the code book will tell you the problem. PSSS-Some1 please have Troy W's Mommy & Daddy take away his keyboard. Just because you can put together a "Lego" car doesn't make you a master mechanic. You only repeated what we said except you have a "Napoleon" complex against any1 plugging something in to a vehicle. It's the same as plugging in a light @ home. In conjunction with "kinder" nine out of ten time in my experience it usually is the oxygen sensor(s) which would be about right with the year model

SOURCE: oil pressure gauge reads 80 psi with engine off and pegs running

That is probably a defective oil pressure gauge or a broken oil pressure sender, it reads 80 psi just because that is the maximum value allowed.

Pressure can be verified by reading it with a gauge tool.
If you really have pressure over 70 psi when engine is running then start replacing the oil filter, and check that the oil lines from pump are not obstructed, if there is nothing in there then replace oil pump.

If instead the gauge reads 80 with engine off, that is a defective pressure gauge.

Most likely the oil pressure sensor is bad. Its located in the very rear of engine on top of bell housing area.

SOURCE: 2004 denali check engine light stays on

There is no p01001, it's either p0100, or p0101.
Anyway, it's the mass air flow sensor that's bad. The p0171 and p0174 is a lean condition on bank 1 and bank 2, which are the oxygen sensors. Change the mass air flow sensor and that should take care of the p0171 and 74 codes.
The mass air flow sensor can cause the 02 sensors to read lean.
The u1301, is a class 2 circuit short to battery. That, you have to test wires to find with a voltmeter/continuity tester.
I would try and find that short before changing the flow sensor, you don't need the new one shorting out, they are not that cheap.

Oil pressure gauge does not reach 40 PSI. Heard the sounds like a loud ticking coming from the engine on the passengers side. Then pressed on the gas peddle and it didn't want to add power. Ticking n


Not sure if there is a question here or not. If the pressure is always below 40 and you are hearing engine noise, chances are the oil pressure really is low. You could replace the sending unit or use a mechanical gauge to verify.

91 plymouth sundance died, oil on ground, check engine on


If you feel like the engine is still ok, I would look at the oil pressure and check engine light issues.
On engines with fuel injection, the fuel pump is powered by the pump relay until the engine starts. Then the engine has to have oil pressure to keep the fuel pump powered.
Its a safety feature so if you are in a wreck the fuel pump does not keep running if the engine is off.
I would want to know why the oil pressure light is staying on and what the trouble codes are in the computer.

How do you know there is a problem with the oil pump?


The oil pressure light or gauge will show that it has low oil pressure and you shouldn't run the engine that way.

it sounds like your oil pressure sending unit may be plugged by whatever took your pressure down to 5-8 psi the first time. this is extremely low pressure as i am sure you know but at 30 psi your light should go off i would replace the sending unit if your oil pressure is holding 30

THOSE NUMBERS ARE VERY GOOD, THE PROBLEM MOST LIKELY IS A DEFECTIVE OIL PRESSURE SENDING UNIT, HAVE REPLACED 100'S OVER THE YEARS FOR THIS SAME ISSUE, GREAT THAT U CHECKED THE PRESSURE THOUGH, IF THE LIGHT WAS INDICATING ACTUAL LOW PRESS U COULD HAVE WASTED THE BEARINGS IN THE ENGINE.

Oil light, noisy engine


If engine is noisy then you have an actual oil pressure concern.Sending unit only reads the pressure. I would recommend you have an actual oil pressure test done to see what your oil pressure is.You didn't mention what engine you have but rule of thumb is 30 psi at 1500 rpm warm engine.

Ticking noise and low oil pressure


DOES IT HAVE A LOT OF MILES ON IT OR MAY BE THE OIL PUMP IS IS GOING OUT? THERE IS A SPRING IN THE PUMP THAT IS A BYPASS FOR HOW HIGH PSI IT MAY HAVE BROKE THAT WILL GIVE YOU LOW PSI.
