Hi

I have a 2001 Elantra GLS with 200k miles, the check engine light came on, can anyone lend me a hand in telling me what this is and how do I go about fixing it.

Thanks in advance for any help

 

P1505 = Idle Speed Actuator Signal Low of Coil #1



The ISCA 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 ISCA valve is to maintain idle speed according to various engine loads and conditions, and also to provide additional air during starting. The ISCA 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.
