My Z28 was throwing a code ECM/Brake Control module code and come to find it out it was the alternator. So i replaced the alternator and the check engine light never came on. Rode it around all day and then it pops on. So i plug up the Diablosport programmer and it reads P0160 02 Circuit No Activity Bank 2 Sensor 2 and P0140 02 Circuit No Activity Bank 1 Sensor 2. I've cleared the codes maybe 5 times and I've tried taking the programmer out of the car all together and putting it back. They still keep coming back on after about an hour of driving. I thought the Diablo erases the codes that are thrown by headers but I keep getting these back or are these even those codes? What could be causing this?
Thanks

 

Rear sensors shut off??

 

contact diablosport and they will tune out the rear O2 codes for you.

 

Well I don't really know if they're off or not I think that it shuts them off automatically because everytime I take the programmer out it'll clear the SES light. It just won't stay off. I've tried going to diagnostics and clearing them and it still comes back on. I've played with it several times trying to find somewhere about O2 deletes but can't find anything.
