IAC System Monitor

Monitoring procedure
The Idle Air Control (IAC) is functionally checked throttle valve opening by monitoring the loop idle speed comparing with the desired idle rpm. If the idle rpm is higher than the desired idle rpm by 200 rpm or lower than the desired idle rpm by 100 rpm, an IAC malfunction is detected. (P0507, P0506)
