Hello, the check engine light comes on with code P0140. I know i have to replace the correct O2 sensor. But i ran across this TSB click link below). Does anyone knows where can i get find the ECM model/pn so that i know if i need to take the car to the dealer to have the ECU updates? Also, can i do all the work and just ask the dealer to update the ECM? How much should the re-program cost? Any suggestion where i can take the car to in southern california, san diego beside dealer that can do this re-program. Thanks. :confused:

Call dealer with VIN they should tell you what ECU is installed.
You can do what you want, some things you may not want. Program costs by a dealer should be based on time the mechanic spends, in this case about 1 hr.

Thanks for your reply. Per code P0140, I think replacing the Heated O2 Sensor Right Rear will fix the problem. I will also try to call the dealer for the ECM part number. I just hope they will give it to me though. Thanks again.
