My airbag light came on in my 2003 gmc envoy


... 2004 GMC Envoy

2004 GMC Envoy, My service engine soon light came on. I took the vehicle to a mechanic and the code came back po422. A smoke check was performed and they said it had a leak in the filler neck and the entire gas tank needed to be replaced. So the dealer replaced the tank and now I'm getting a loose gas cap message light on the dash. Since the dealer did not replace the cap when replacing the tank is that what the problem is, or was it not the gas tank issue at all?


Hello: Without being there when the smoke test was performed no one can say what the results of the smoke test were. I would go back to the dealer and speak to the service director/service manager and request a new gas cap. ... 2004 GMC Envoy

There may be a loose wire or the gauge or sending unit may be going bad. The first thing I would do is to hook up a temporary oil pressure gauge, not using the old one at all. With this watch gauge while driving and see what readings you get. If the ... 2003 GMC Envoy Xl

You will need to replace the fuel level sensor which is in the fuel tank.They have a lot of problems because the metal fingers on the sensor wear off and gives you the incorrect readings.This will also cause the check engine light to come on.You will ... 2005 GMC Envoy Xl

My check engine light stays on, my instrument panel dings while driving the vehicle, the gauges drop to 0 and back up again, it switches back and forth from unknown driver to driver 1 repeatedly, abs light and brake lights come on, loses track of fuel level range - sometimes just showing 3 dashes. . . all while driving my 2004 gmc envoy


For quirky things like that, I' look first at your ignition switch (common problem). Not the switch the key goes into, but it' located under the steering wheel column cover, on the bottom (black). Did your key get stuck in the ignition too at som ... 2004 GMC Envoy

2006 GMC Envoy XL gas gauge reads empty after filling, then slowly moves up after driving but will continue to lose pressure until it reads empty and the light is on, then the check engine light came on. my problem is the same as all the rest. never had a problem until a fill-up at 96000 miles. now every fill-up the same. fuel gauge goes empty then after awhile it works ok.

2006 GMC Envoy XL gas gauge reads empty after filling continues reads empty and the light is on then the check engine light came on what can be the problem how ca i fixe it to save mesome $$$

Hello, I have a 2002 GMC Envoy and my check engine light is on. The code populated is P0014, I've read different solutions to this code, however I am still unsure as to which route to go. Would the replacing the Camshaft sensor resolve my issue? Also, when my AC is on the timing appears to go up and down (from 0-2), as if my truck wants to shut off, and then Pressure Oil Low // Stop engine displays. Thank you for any assistance you can provide.

Clean your throttle body. Once the battery is disconnected and the computer reset, it no longer increases power to make up for a dirty throttle body. Get a $4 can of carb cleaner. If you go to a mechani9c they will tell you that it is the ac compress ... 2004 GMC Envoy

I have a 2004 GMC Envoy that has all of a sudden developed a rough idle. It seems to get worse as the engine gets hotter. ie: after driving for 15 minutes . Everything else is fine. Runs great, same gas mil, no service engine light. I am sure this has nothing to do with it but this came about after the smog test I had a month ago.


There is a small chance that something was knocked loose when they did the test. be that as it may you seem to have one or two problems. one of the sections of the coil pack may be failing and need to be replace. quick test for this is to pull one ... 2004 GMC Envoy

Check engine light on 2004 GMC Envoy. Had air intake sensor replaced. Failed inspection diagnostic code came up P0128. I have been told I needed an air pump, a tune -up, injectors cleaned etc. etc., I have spent a ton of money and still failed inspection. I did not have the air pump put on yet, does this code mean it is actually the pump


Code P0128 indicates a faulty thermostat, more than likely it is always in the open position causing the coolant to come up to operating temperature too slowly.My suggestion is to find a different repair shop. ... 2004 GMC Envoy
