Code P0507 2017 Chevrolet Silverado Description

The Engine Control Module (ECM) is the control center for the Throttle Actuator Control (TAC) system. The ECM determines the driver's intent based on input from the accelerator pedal position sensors, then calculates the appropriate throttle response based on the throttle position sensors. The Direct Current (DC) motor, located in the Throttle Body Assembly, drives the throttle blade. In order to decrease idle speed, along with spark and fuel delivery changes the ECM commands the throttle closed reducing air flow into the engine and the idle speed decreases. In order to increase idle speed, the ECM commands the throttle plate open allowing more air to pass the throttle plate. The Diagnostic Trouble Code (DTC) will be set when the actual idle speed is approximately 188 RPM greater than the desired idle speed.

Code Tech Notes

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.
