3. Idle Speed Inspect

1. Start the engine. Hold the engine speed at 3,000 rpm without load (in P or N) until the radiator fan comes on, then let it idle.
2. Check the idle speed under no load conditions: headlights, blower fan, radiator fan, audio system, and air conditioner off.

   Idle speed should be: 680 +- 50 rpm (in P or N)

3. Let the engine idle for 1 minute with high electric load (A/C on, temperature set to max cool, blower fan on high, headlights on high beam).

   Idle speed should be: 680 +- 50 rpm (in P or N)

   NOTE: If the idle speed is not within specification, do the PCM idle learn procedure. If the idle speed is still not within specification, go to the symptom troubleshooting.
