Here is the deal, Smog test fail because the computer ECU can't read or not receiving any data at all from any sensors, passed inspection & tailpipe was below guideline. Will getting an used ECU fix the problem? I am selling the car and can't pass the smog. Dealer wants to charge from $89 to $189 to just diagnostic the car, then plus repair. I sold the car for $2000.

No check engine light, has 225k miles, where do I start? Help!

Does anyone know If I need reset the ecu or get an used one.

ECU not ready is a common occurance if your car has recently had problems or the ECU has been reset recently. It needs to go through several complete cycles, engine running correctly with no problems detected before it will go into a ready state. Take a few long cruises over the next few days and try to have it inspected again.

There is nothing wrong with your ECU.

Thank you for all info. The last time the battery was disconnected was 7 mo ago. I will go to auto zone to get them scan.
