If the O2 sensors have been deleted, they will need to be replaced in order to pass inspection.

You will also need the ECM to tell the inspection machine that the emissions system is working and has passed internal tests - I don't know if an aftermarket ECM will do that.

Good luck.

I have taken the car in to get a smog check already and watched them do the check on the car in front of me. All they do is hook up the machine and then run something and you get a pass or fail. The inspector never looks under the car or under the hood. AZ is pretty easy on the smog check.

I no longer have my factory ecu/ecm. The O2 sensors are still installed but the code reader that my friend hooked up was reading that they had been deleted. Not sure how I get those back. Do I need to have someone code them back in or do I need a new tune and a new ECU?
