2008 cobalt fault codes
I have a problem that is causing fault codes P0036 (HO2S Bank 1 sensor 2 heater circuit), P0054 (HO2S Bank 1 sensor 2 heater resistance), and P0036P on a 2008 cobalt LT with 2.2L engine. It seems strange that I have P0036 and a pending P0036. Can any one explain what may be causing these faults. I do not want to randomly replace the O2 sensors. Any feedback is welcome.
Thanks
