service engine light on 2001 tahoe

[waxworm09]

I have a 2001 Tahoe with the service engine light on. I brought it in and the mechanic told me it was a sensor by the gas tank that was bad. It had something to to with emissions, and he said it didnt have to be replaced, had nothing to do with the way the vehicle runs so I saved the money and didnt have it replaced. The sensor was over $200 and since its not necessary to have im not going to replace it, my question is how do I turn the service engine light off? Is there a fuse or something I can do to turn the light off? Thanks for any advice!

the only way to turn off the light is to make the repair and clear the codes. There is not a fuse for the check engine light. Just clearing the code will only turn it off until the computer detects the fault again and then it will turn it back on.

A custom tune would clear the code I think(about $200), but it would also give you better gas mileage and more power.

If it's the fuel tank pressure sensor, don't worry. When your fuel pump fails, that part comes with the new pump.

However, it's always best to "fix" the light in case a code that's more important to you pops up.
