Check Engine Light
 

Okay so i put an off road y pipe on my truck which elmonates the cats and the rear O2 sensors. which has caused the check engine light to come on clearly. so my question is is there any way i can cancel the code coming from the 2 rear sensors tripping the light??? will a diablo sport preadator cancel them? thanks guys

My understanding the predator will, but you can go to their website and ask on their forum, they are very good at getting back to u asap

Or get some O2 simulators and call it a day. They are about $30 a piece.

well i was planning on gettin a chip any how i just wanted to make sure it would cacel the codes as well in which it does i found that out today so i went ahead and bought one and should be here tomo.

Never heard of a chip doin that friend. Only way I know it can be done is either a custom tune, or O2 simulators. Not even a Hypertech or Superchips pragrammer can do that.

Where can i get those O2 simulators from?
