Idle Speed Inspection: Inspection

NOTE: 

• Before checking the idle speed, check these items:
• • -

    The malfunction indicator lamp (MIL) has not been reported on, and there are no DTCs.

  • -

    Spark plugs

  • -

    Air cleaner

• Apply the parking brake.

1. HDS - Connect 
2. 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:  *1: Idle speed is controlled to improve driving performance at the high altitude point of view . 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: 720 +/- 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 .

   1.5 L engine	720 +/- 50 rpm  (in P or N)
   	975 +/- 50 min -1 (rpm)  (in P or N) *1 (high altitude (BARO sensor in the DATA LIST with the HDS: less than 563 mmHg)
   2.4 L engine	720 +/- 50 rpm  (in P or N)
