stored in the engine control module (ECM)/powertrain control module (PCM). The ECM/PCM monitors and
controls the idle speed so that the actual idle speed is equal to the target idle speed. If the actual idle speed
varies beyond a specified value from the target speed over a certain period of time, the ECM/PCM detects a
malfunction in the idle speed control system and a DTC is stored.

MONITOR DESCRIPTION

Enable Conditions

ENABLE CONDITIONS

Malfunction Threshold

The actual idle speed is at least 100 rpm less than the target idle speed for at least 20 seconds.

Driving Pattern

1. Start the engine. Hold the engine speed at 3,000 rpm without load (in Park or neutral) until the radiator

fan comes on.

2. Let the engine idle for at least 20 seconds.

Conditions for illuminating the MIL

When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the ECM/PCM
memory. If the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and the
freeze frame data are stored.

Conditions for clearing the MIL

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic
runs.

The MIL, the DTC, the Temporary DTC, and the freeze frame data can be cleared by using the scan tool Clear
command or by disconnecting the battery.

General Description

A target idle speed that meets the engine operating conditions (coolant temperature, A/C ON or OFF, etc.) is
stored in the engine control module (ECM)/powertrain control module (PCM). The ECM/PCM monitors and
controls the idle speed so that the actual idle speed is equal to the target idle speed. If the actual idle speed
varies beyond a specified value from the target speed over a certain period of time, the ECM/PCM detects a
malfunction in the idle speed control system and a DTC is stored.
