Idle Speed Inspection

• Before checking the idle speed, check these items:
  
  • The malfuction indicator lamp (MIL) has not been reported on, and there are no DTCs.
    
  • Ignition timing
    
  • Spark plugs
    
  • Air cleaner
    
  • PCV system
    
  • Headlight OFF
    

1.	Disconnect the evaporative emission (EVAP) canister purge valve connector.

2.	Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.

3.	Start the engine. Hold the engine speed at 3,000 rpm (min-1) without load (in Park or neutral) until the radiator fan comes on, then let it idle.

4.	Check the idle speed without load conditions: headlights, blower fan, radiator fan, and air conditioner off. Idle speed should be:  KE, KG, TR models: M/T  670±50 rpm  A/T  670±50 rpm (in Park or neutral)  Except KE, KG, TR models: M/T  750±50 rpm  A/T  750±50 rpm (in Park or neutral)

5.

Let the engine idle for 1 minute with high electric load (A/C switch on, temperature set to max cool, blower fan on High, and headlights on high beam). Idle speed should be:  M/T  710±50 rpm  A/T  710±50 rpm (in Park or neutral)  NOTE: If the idle speed is not within specification, do the ECM/PCM idle learn procedure. If the idle speed is still not within specification, go to symptom troubleshooting.

6.	Reconnect the EVAP canister purge valve connector.
