hey guys, i believe this is an 02 sensor wanring. for some reason, yesterday morning, this code popped up and everytime i qwipe it away, it keeps coming back!!! i havent had any issues with this code and ive had turbo on for over a year... any help?

 

That code is for the O2 heater circuit. Make sure you have no blown fuses and verify the wiring is good.

 

well, i just had a new aftermarket alarm installed and i know he had to disconnect the guage because i had a ton of wiring under the dash, could he have maybe hooked up my aem wideband wrong?

 

Or blown a fuse maybe. There should be heater circuit fuses under the dash and in the engine bay. Check them.

 

ok ill check it today, thanks MIA

 

hey MIA, i just a had anew alarm system installed and he ahd to disconnect all my guages for some reason and reconnect them. could there be a connection with the wideband a/f guage from aem i have to that check engine code? Only reason i ask is because right afte he was done with alarm install, the service engine soon light came while i was still in the bay! just seems like a wierd coincidence.
