Abstract

The P0507 error code in your GMC indicates that the engine's idle speed is running higher than the expected range, typically above 200 RPM from the target idle speed. This code is triggered when the Engine Control Module (ECM) detects that the Idle Air Control (IAC) system cannot bring the idle speed down to normal levels.
