How to Fix the DTC P0507 Pontiac?

Review the 'Possible Causes' mentioned above and visually examine the corresponding wiring harness and connectors. Ensure to check for any damaged components and inspect the connector pins for signs of being broken, bent, pushed out, or corroded.

Code Tech Notes

If there are no intake leaks, clean the throttle body, adjust the engine idle, and erase the engine code. If the code persists you may have to replace the Electric Throttle Control Actuator (Motor).

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

Code P0507 Pontiac Description

The Idle Air Control (IAC) Valve is a Powertrain Control Module (PCM) controlled stepper motor located on the Throttle Body. The stepper motor drives a valve pintle which protrudes into a passage that bypasses the throttle plates. The PCM commands the Idle Air Control Valve pintle to extend to decrease the idle speed. The bypass air flow is reduced and the idle speed decreases as the pintle approaches its seat. The PCM retracts the IAC valve pintle away from its seat to increase the idle speed. The retracting of the IAC valve pintle allows more air to bypass the throttle plates. One of the PCMs uses for the IAC system is to maintain a desired idle speed. The P0507 Diagnostic Trouble Code (DTC) is set when the Powertrain Control Module detects an engine speed outside of the Idle Air Control range of control.
