Idle Control System RPM Lower Than Expected


The execution time is once per driving cycle and the duration time is 20 seconds or more. Throttle fully closed, fuel trim 0.75-1.47, intake air temperature 19 ºF (-7 ºC) and battery voltage 10.5 or more. If the actual idle speed varies beyond a specified value from the target speed over a certain period of time, the PCM detects a malfunction. The actual idle speed is at least 100 rpm less than the target idle speed for at least 20 seconds. NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot.
