content: I had an O2 sensor at the back end of my catalytic converter go bad. The cost to fix it was insane and it didn't effect emissions. I went to have my car inspected and they wouldn't let me pass because of my check engine light. I went out and bought an OBD2 interface for 20 bucks, connected my phone and cleared the cars computer a minute before inspection. The car went through just fine. This might work for you.
