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: On my 2007 GMC Sierra

I have the same problem on my '07 gmc 2500. I understand there is a problem with the "cannister filter for emission control of fumes from gas tank" (or something like that). Apparently, it is located near the gas tank which causes it to plug up easily from road dust. The fix is to relocate it with long hoses into the engine compartment area. Since the filter alone is $250 (or so I've been told) with labor it's a $350-400 fix. Supposedly, there is no damage that can be done so I'm just tooling along without worrying about it until I have to put the truck in the shop for something else. Seems there ought to be a recall for this, by government motors won't come out with it.

GMC Yukon 1999, parking lights stay on when truck turned off, why?


If you pull the 20amp park lamp fuse and the lights stay on, it almost has to be a short inside the headlight switch.
Will the lights go off if you unplug the headlight switch ?

I replaced my water pump in my 1999 gmc yukon my check gauge light stayed on and temp gauge stayed over to hot side. can i reset it?


Not exactly.
The check gauge warning light is on because the temp gauge is reading hot.
Does the temp gauge read hot as soon as you turn the key switch on, or not until the engine as run for a few minutes ?
If it reads hot without the engine being started, there may be a short in the wiring or the sensor may have failed.

Cant locate ecm fuse


The fuses for the computer are in the box near the battery. Not sure why you need them, if you are trying to turn the check engine light off you have to clear the trouble codes with a scanner.

Reset service light 2001 yukon


the answers above do not work. batter cable off does not work. that turn on 5 pedal thing is BS. also some a holes online are saying undo the fuse cover under the steering wheel and and unplug the ECU - well the fuse panel is not under the wheel, it's on the drv side of the dash. AND even when you pull that there is nothing called a ecu. funny hu. there is not a ECU fuse in the under hood fuse box either. service engine soon light is STILL ON. It was flicked on from the air breather intake being loose. that has been fixed. gas caps on tight. engine oils been changed.

How do you reset the check engine light on a 2003 gmc yukon xl


the check engine light means you have a trouble code in your vehicles computer. After fixing the problem with the yukon the check engine light can be reset sometimes by disconnecting the battery and disconnecting the ECM fuse. Although some parts stores are known to check your codes for free they might also clear them with a scan tool.

Service engine light staying on


Hello tdamm...No...the service engine soon (SES) light on your yukon is not telling you to change the oil.
This is a warning light that is illuminated when there is a problem affecting the Emission system and the engines computer management (ECM) has detected it from a fault. It could be something as simple as a loose or defective gas cap. If the SES light is blinking, it's more serious....
The yukon needs to be connected to diagnostic equipment (scanner) for fault diagnosis.
You can go to autozone they will hook up an OBD II scanner to your vehicle and explain the codes to you.
Good luck...i hope this helps and will fixya up.
