Description DTC P0507 Idle Air Control System

When the TP sensor’s signal indicates closed throttle position and the engine is idling, the ECM adjusts the idle speed control actuator so that the engine runs at the correct idling speed, regardless of coolant temperature, load and etc. When the additional load applied in the engine, the air flow through the idle speed control actuator is increased momentarily to raise the idling speed. The idle speed control actuator is the double coil type and has two coils. The two coils are driven by seperate driver stages in the ECM. Dependibg on the pulse duty factor, the equilibrium of the magnetic forves of the two coils will result in different angles of the motor. In parallel to the throttle valve, a bypass hose line is arrange, where the idle speed actuator is inserted in.
If the actual engine speed is higher than the target engine speed at idle, the ECM judged as a fault and DTC is set.
