WARNING: This page is about a different car, the 2003 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Ensure ACCELERATOR PEDAL RELEASED POSITION LEARN and THROTTLE VALVE CLOSED POSITION LEARNING have been performed before continuing.

Start engine and warm to normal operating temperature.
Ensure all conditions under PRE-CONDITIONING are met.
Select IDLE AIR VOL LEARN in WORK SUPPORT mode with CONSULT-II.
Press START and wait 20 seconds.
Ensure CMPLT is displayed. If CMPLT is not displayed, IDLE AIR VOLUME LEARNING will not be carried out successfully. In this case, find the cause of the incident. Proceed as follows:
1. Check that throttle valve is fully closed.
2. Check PCV valve operation.
3. Check that downstream of throttle valve is free from air leakage.
4. When the above 3 items check out OK, engine component parts and their installation condition are questionable. Check and eliminate the cause of the incident. It is useful to perform TROUBLE DIAGNOSIS - SPECIFICATION VALUE in TROUBLE SHOOTING - NO CODES article.
5. If any of the following conditions occur after the engine has started, eliminate the cause of the incident and perform IDLE AIR VOLUME LEARNING all over again:
  - Engine stalls.
  - Erroneous idle.
Rev up engine 2 or 3 times and ensure that idle speed and ignition timing are within specifications. M/T and A/T in Park or Neutral: Idle speed: 700-800 RPM, ignition timing: 10-20 BTDC.
