Tech Notes for P0507 2014 GMC Sierra

If there are no intake leaks, clean the throttle body, adjust the engine idle, and clear the engine code. If the code persists you must replace the Electric Throttle Actuator Motor (Located in the Throttle Body Assembly).

The Engine Control Module (ECM) learns the idle position of the throttle plate to ensure the correct idle. Anytime the throttle body is cleaned or replaced, the ECM must learn the new throttle position. The idle may be unstable or a DTC may be set if the throttle position is not learned.
