Check Engine o2 sensor ZZP Catback
I have the Full ZZP exhaust. Mid length Header and Catted downpipe with 2.5 inch Catback. I knew that when i got this installed , it would set a code for the rear o2 sensor and i would have a check engine light. I got some suggestions on how to get the light to go off, and i purchased an o2 spacer to fix the problem . i installed it and the check engine light still wont go off. so the spacer idea failed. I need to know what else i can do to get the light to go off. its just annoying and my inspection is also coming up in a month. i would like to get the light to go out by then. Will the dealership turn off the sensor for me with a TEch OBD2 device or is that against the law for them to do so? if so how do i fix it?
