Idle Switch Circuit

Idle Switch Circuit

CIRCUIT DESCRIPTION
When the "IDLE" terminal of ECM is turned ON, a signal is sent to the ECU. The ECU uses this signal to correct the discrepancy between the throttle valve position and the actuator position sensor valve to enable accurate cruise control at the set speed. If the idle switch is malfunctioning, problem symptoms also occur in the engine, so also inspect engine.
