Answers :

The fault codes don't always indicate the actual part failure, but the general area of a possible problem. The first thing to do with a problem like this is to clean the throttle body. Make sure to disconnect the battery when doing this procedure because it will cause the computer to reset and relearn with a clean throttle body.
