My 01 F150's sevice engine light came on, so I went to Autozone to have it code scanned, it said engine bank lean, so I replace the air filter, it was nasty. Now how do I reset the light to see if that was the problem. BTW, the truck has less that 75K on it, so I am trying the small stuff before I start on the sensors.

 

use the exact fault code(s) as your SEARCH argument.

You'll probaboy find helpful advice.

 

Disconnect the battery and turn headlamps on, that will reset the code. The clogged air filter should have made it too rich, not lean though so I expect the code will return....look for vacuum leaks.
