It probably wan't your problem. Just because you get a certain code, doesn't always mean the sensor is the issue, it's another problem that the sensor detects. Scan for the codes again and post the 4 digit codes back here so we can help.


Was the code reset after you replaced the questionable part?


Clear the code and see if it reappears.
