Idle Speed Inspection

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2015 Honda Crosstour, 2014 Honda Crosstour, 2013 Honda Crosstour, 2012 Honda Crosstour, and 2011 Honda Accord Crosstour. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Before checking the idle speed, check these items:
- The malfunction indicator lamp (MIL) has not been reported on, and there are no DTCs.
- Ignition timing
- Sparkplugs
- Air cleaner
- PCV system
Apply the parking brake, and make sure the headlights are off.

Disconnect the evaporative emission (EVAP) canister purge valve connector.
Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.

Make sure the HDS communicates with the PCM. If it doesn't, go to the DLC circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ).
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.
Check the idle speed without load conditions: headlights, blower fan, radiator fan, and air conditioner off.
Idle speed should be: 650 ± 50 rpm (in P or N)
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: 700 ± 50 rpm (in P or N)

NOTE: If the idle speed is not within specification, do the PCM idle learn procedure (see PCM IDLE LEARN PROCEDURE ). If the idle speed is still not within specification, go to symptom troubleshooting.
Reconnect the EVAP canister purge valve connector.
