P1508 Idle Charge Actuator Signal High of Coil #2 - General Information

Component Location





General Description

The Idle Charge Actuator Valve(ICAV) is installed on the intake manifold and controls the intake airflow that is bypassed around the throttle plate to keep constant engine speed when the throttle valve is closed. The function of the ICA valve is to maintain idle speed according to various engine loads and conditions, and also to provide additional air during starting. The ICA valve consists of an opening coil, a closing coil, and a permanent magnet. Based on information from various sensors, the PCM controls both coils by grounding their control circuits. According to the control signals from the PCM, the valve rotor rotates to control the by pass airflow into the engine.
