Hey I had a mechanic tune my car and do everything with the cobb tuner . I have ets v2 exhaust no cats or mufflers

He told me when he put the tune onto my car it would flash any check engine lights or sensors so that I would be able to pass inspections

Took my car for inspection today and it did not pass due to two sensor readings I believe he said??
Any help or general ideas what is going on ? Thanks !

 

Not sure about PA, but inspection in VA will often perform a visual check. Lacking a cat in most cases will result in a failure.

 

some of the sensors have to go through checks, and show "readiness" that they passed those tests. untill then the car wont pass inspection. drive it for a couple days and go back if there are no CEL. when you flash the tune it resets the ECU and the sensors so the checks and tests have to be performed again
