Code P1507 2006 Ford Fusion Description

The P1507 diagnostic trouble code (DTC) for a 2006 Ford Fusion indicates an "Idle Air Control Under Speed Error." This code is triggered when the Engine Control Module (ECM) detects that the idle speed is lower than the desired RPM range. The idle air control valve (IAC) is responsible for regulating the amount of air entering the engine at idle to maintain a stable idle speed. When the IAC fails to operate properly, it can lead to erratic idle speed, stalling, or rough idling.
