Idle Speed Inspection

NOTE: Before checking the idle speed, check these items:


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

2.Connect a tachometer (A) to the test tachometer connector (B), or the HDS to the data link connector (DLC) (C) located under the driver's side of the dashboard.

 

 

3.Start the engine. Hold the engine 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 are not operating.

Idle speed should be:
M/T 650±50 rpm (min-1) 
A/T 650±50 rpm (min-1) (in Park or neutral) 

5.Idle the engine for 1 minute with A/C switch ON, temperature control at maximum cool, blower fan at maximum speed, rear window defogger ON, head lights at high beam, then check the idle speed.

Idle speed should be:
M/T 700±50 rpm (min-1) 
A/T 700±50 rpm (min-1) (in Park or neutral) 

NOTE: If the idle speed is not within specification, do the ECM/PCM idle learn procedure. If the idle is still out of specification, do the symptom troubleshooting.

6.Reconnect the EVAP canister purge valve connector.
