Hi All, I'm in Florida and my car back home in VA is throwing a code: MIL Command On-Fail and it said something about a o2 sensor heating circuit, is there a way to trace it down which sensor it is? will this affect gas mileage? I need to know what I can do to fix this or if it won't really hurt anything (including mileage) can I just wait till I tune out my o2 sensors and just keep the upstream ones.

Oh, and the car is a 2002 Camaro Z28 ls1 automatic. Thanks for your help.

If scanned it should tell you what Bank, which sensor, Example, bank 1 sensor 2. If it is the front 02 then yes it will affect idle quality and gas mileage..
