Had Autozone read a code from the emissions light, it read P115E which is the "Throttle Actuator Control Throttle Body Air Flow Trim at Max Limit." What does this mean?
Should be a 4 digit code. P115E is not a valid code. ex. P0300
Its the code you mentioned TAC control. Ford guys know the code, Remove the throttle body and give it a good cleaning. Use a cleaner specified for throttle bodies. I always check fuel pressure when this code appears make sure its not dropping as the engine accelerates IDS-VCM is good for PSI check. For guys that want to learn I suggest iATN as a worthy reference.
