Check engine light

there can be many reasons. if it is driving normally and there are no other lights or it is not running badly it might be a small problem or even not a problem at all. more likely a EVAP code but it is best to have it checked. if you go to napa, auto zone, orilies, pep boys or really any auto part store they can check the code for free. if you let us know or write me with the code I can help you through it.

Might be time to "check your engine"

Hi, I'm experiencing the same. The code P0455-00 relative to the Evap is what I received when a diagnostic scan was done. It was cleared and stayed gone for 2 days. It has since reappeared. What direction should I take to resolve this matter?

Check gas cap first then look for rotted or broken evap lines if all that checks replace evap solenoid at canister

Yes still having check engine light. Replaced the original GM gas cap and check lines for leak and still nothing. Do I have to reset it somehow or is it a fuse?

Can a leaky sun roof cause ur engine light,stability light and to come on in my h3 2007 hummer from the water ?? Water also comes out of my phone speaker over driver seat.

What is this red indicator on 2007 H3, searching online for days, can’t find it, believe it or not. The check e fine light is always on due to gas cap, changed it three times, confirmed with different garages the code that comes up is for gas cap. Can anyone please tell me what the top Center light is???

The upper light is for low tire pressure.

Shari that's for low tire pressure..
