Component Location





General Description

The ISCA (Idle Speed Control Actuator) is designed to maintain a steady desired idle speed. Idle airflow is adjusted through the idle air actuator in order to maintain the desired idle speed under various load conditions. Load conditions vary due to numerous factors, such as engine temperature, air conditioning, electrical load and power steering load.

DTC Description

If the real engine speed is lower or higher than the threshold value of desired engine speed during catalyst heating, ECM sets P0505.
