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: location of fuse box/panel for 2004 yukon denali xl

There are 2 fuse panels in the Denali.
One is a panel on the drivers side, its on the dash but facing the door.

The ohter is under the dash and above the pedals, this one is much tougher to access.

Your Owner's Manual should tell you where the fuses are that you need to access.

SOURCE: lost reverse on GMC Yukon Denali vortex drives

WOW sorry to hear that.

this is a common problem with the 4l60e transmission, what has happend is the gear has sheared off the back of the sun shell, you should have lost reverse and if you will watch your tachometer the next time you drive you will notice you allso lost forth gear.

you will nedd to have the transmission removed and disassembled for the new sun shell, make sure you get the hardened sun shell, this is not a rebuild but simply a repair. you can get a stock sun shell for about $65.00 or a heavy duty one for about $100.00, make sure you find a good tranny guy to provide the labor, oh the transmission paper rubber kit "reseal kit" shouldnt be more than about $80.00

good luck

I own a 2008 GMC Envoy Denali, 2WD. Yesterday the engine would barely idle and numerous lights on the dash came on including the check engine light. I had a friend check the diagnostic codes and it came up...


Five days prior to this, the battery had to be replaced. The engine was started without the pause for two minutes ?????? Where do you people come up with some of this stuff ? Pausing for two min. before starting has nothing to do with it . DTC P0651: 5-Volt Reference 2 Circuit
Some of the engine sensors on your vehicle work off of a steady 5 volt supply by the PCM - engine computer . One of these sensors is short internally bring down the PCM .

That's why it wasn't running good ,an lights lit on the dash. Your best bet , take it to GMC dealer .
No where in GM service info does it say after replacing the battery that you need to wait two min. before starting .
Position the positive battery cable (1) to the battery.
Tighten the positive battery cable bolt.
Tighten
Tighten the bolt to 15 N·m (11 lb ft).
Connect the negative battery cable. Refer to Battery Negative Cable Disconnection and Connection .

Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

Sounds like a sprocket in my 2008 Yukon denali striped out. Goes in reverse but not forward


Could be a valve body problem, a shift solenoid problem or the transmission control module causing this.

Everytime I start up my 2010 Yukon Denali, the clock on the panel reads 1 hour more? I reset it and the next time that I start it, it changes again.


Weird, are you resetting the clock and finishing the setting as per your manual. Your navigation zone could be throwing it off, make sure you have correct zone for where you are. press the helpful button, and check video link below.
