P0220 Code for 2004 GMC Denali

The auto zone attendent stated this would most likely be the gas pedal sensors but after reading, looks likt that may not be the issue. I have the reduced engine power comment come across my dashboard. It as done this now about six times and I normally just turn off the ignition and it automatically resets...This happened about a year ago and only happened once but now this seems to be once a month.

Go to an Advance or Auto Zone and ask them to read your fault codes. This is a service they will do for free in hopes of selling you a replacement part. You likely have a faulty sensor that is causing the light to come on. Good Luck! I hope this is very helpful!

SOURCE: 2004 Mazda Tribute V6 will not stay running

Try this, it's cheap, easy and it won't take long...and it will probably help...

I have a 2001 Tribute and ithas had this problem since about 1 year after buying it new. My motherin law also has one and it has the exact same problem. You can crankthe car2_bing.gifcold (sometime even warm) and it will die unless you keep the gas pedal pressed in. I suspect that this is a widespread problem with theTribute. Forget about the Mazda dealer helping. There is a very simpleand cheap solution:

1. Locate the idle air controlvalve...looking at your engine from the front of the car2_bing.gif, the valve islocated on top of the air intake towards the far right corner of theengine (next to the plastic cover on top of the engine). The valve ismetal, looks like a small metal cylinder is attached to it, and isbolted on with two bolts. It also has wires plugged into it. You can goto google images2_bing.gif and type "Mazda tribute idle air control valve" to see what it looks like.

2. With engine off, unplug the wires from the valve.

3. Remove the two bolts and take valve off of air intake.

4.Inside the metal part you removed, you will see two chambers with ashaft going through them that can extend back and forth. The shaft hasa spring on it, and a plug that can open or plug a hole between the twocavities. This is the idle control valve.

5. Take a flat headscrew driver and pry the shaft back and forth a few times to free itup. There will probably be some dirt/grime on the shaft.

6. Takecarburetor cleaner and spray it in the valve cavities. Allow it to soakfor a minute and drain it out. Repeat if needed to clean it out.

7. Blow in it to dry it out.

8. Take WD40 and spray it in the cavities. Drain excess out
.
9. Take the screwdriver and work the shaft back and forth a few more times. The shaft should move freely.

10. Bolt the valve back onto the engine air intake and plug the wires back up to it.

Startthe engine. If this was the problem, and the engine was stalling justbefore doing this procedure, then it should start right up and idlefine. If it was stalling sporadically when started, it should not anymore. I have to do this procedure with my car every 6 - 12 months. Whenthis problem first occurred with my car it took it to the dealerseveral times. Of course it would not do it at the dealer, and theyclaimed ignorance as to the cause. I suspect this is a cash cow forMazda.

SOURCE: I have a 2003 GMC Envoy and the check engine light

This code relates to low coolant temperature not the 02 sensors. You should change your thermostat, it's stuck open and is not allowing the engine to properly heat up.

By the way, there are 2 92 sensors on Envoys and Trailblazers. One of them upstream is in the engine compartment right off the exhaust manifold, easy to replace. The other one downstream is next to the transmission drain plug in the exhaust pipe.

SOURCE: error code p1271 on trailblazer

That trouble code is faulting the accelerator pedal sensor. The APP sensors are located in a TAC module mounted to the accelerator pedal bracket. There are three individual APP sensors within the TAC module. Three separate signal circuits, low reference circuits, and 5v reference circuits are used to determine the accelerator pedal position. The APP sensor signal voltages increase when the accelerator pedal is depressed.

What fixes codes p1515


Throttle Body Sensor or your accelerator pedal is the cause of code P1515. Your GMC or Chevy truck gas pedal is controlled by the vehicle's computer. I know what a idiotic feature.. But replace that & clean or replace your mass airflow sensor as well... Problems resolved!!!

I HAVE A 2002 DENALI THAT I JUST PURCHASED. IT HAS 253000 MILES ON IT. I HAVE DROVE IT FOR 3 DAYS AND NOW MY SERVICE ENGINE SOON LIGHT IS ON. CAN YOU TELL ME WHAT PROBLEMS IT COULD BE?


Time for oil change? Loose gas cap? Auto zone and several other parts stores will hook a reader to the plug under the steering column and read the code. Best news is they do it for free.

How do you correct repair code P0332 and how what should the cost be for a 2004 gmc denali?


P0332 Is set by a knock sensor, desiganted by GM as "Knock Sensor 2".

There could be many causes for this, from a misfire, to a loose sensor; so an appraisal from anyone without access to the vehicle is out of the question.

2003 gmc denali service stababilty light


In order to know what the problem is, you need to have the error code(s) read. Try any mechanic... or many auto parts stores will check the codes for free.

From there the codes can be interpreted and a course of action determined.

2004 GMC Yunkon Denali is misfiring


it could be alot of things...you could start by routine maintnence( new spark plugs, spark plug wires, air filter, oil change, the in line fuel filter) also take into consideration what kind of gas you are using...i know it sucks spending $100 a week in gas with your AWD 6.0 liter V-8...but if ur not running premium it could very well be your problem. I have also heard of the denali's having oxygen sensor issues...is it throwing a check engine code?

Coolant Temp Sensor


The sensor is located on the drivers side engine block...although you can see if from looking from the top of the engine, you would have to get under the vehicle and look up to replace it. Be aware that it takes a special tool to unscrew the old one and screw in the replacement.
