Hey Guys,

Was just told at my inspection that my o2 sensor/o2 sensor heater is not reading ready so i am not passing inspection.

How can I tell if my rear o2 is turned off or on in my tune? I have a cobb catted downpipe so I did not think I would be having issues.

Appreciate the assistance. everything else is showing fine just those 2 parameters.

call your tuner, most stage three tunes shut of the rear 02 monitor. if you live in an inspection state, I would recommend getting it turned back on and using a non fouler to keep from getting a code (which will also cause you to fail)
