SOURCE: i have an engine code PO332 knock sensor 2 circuit

The most likely cause of your code is a bad rear knock sensor. You should check the knock sensor wiring harness for corrosion. But if that checks out the sensor will have to be replaced. The knock sensor is under the intake manifold, although it's not too difficult to remove. Both knock sensors should be replaced along with the wiring harness, just because of labor involved in gaining access to the sensors. You could try clearing the code, it may stay off for a long time.

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

Code po449 is the canister vent valve solenoid error.This is a common problem with these valves because they are under the truck in the rear by the spare tire and they get all the dirt and water and snow,if you live in an area where you get snow.You will find it on the canister under the vehicle by the spare tire.

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.

My 2001 yukon xl 1500 consistently flashing check engine light when cruising at high speed downhill after running for ~30 minutes. The engine preformance appears unchanged while the light is flashing. ...


OK, if you have a misfire at a high rate of speed and it is intermittent, I wouldn't worry about it unless it makes the engine lose power or affects gas mileage.

If you want the engine to work perfectly, however, I would find out which cylinder is missing, and correct the problem by replacing coil packs or what not until it doesn't do this anymore.

Also, a bad O2 sensor can cause a 'random' mix that may come and go over time.

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.

This means there is a fault in the four wheel drive system, the light reset's each time the key is turned off, then it tests itself after the engine is started, if the fault occurs again the light will come back on.
