Without CONSULT-II

WARNING: This page is about a different car, the 2002 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: It is better to count the time accurately with a clock.
NOTE: It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit has a malfunction.
  1. Preform ACCELERATOR PEDAL RELEASED POSITION LEARNING .
  2. Perform THROTTLE VALVE CLOSED POSITION LEARNING . Start engine and warm to normal operating temperature.
  3. Ensure all conditions under PRE-CONDITIONING  are met. Turn ignition off and wait at least 10 seconds. Ensure accelerator pedal is fully released.
  4. Turn ignition on and wait 3 seconds. Fully depress and fully release accelerator pedal quickly 5 times within 5 seconds. See Fig 1.
  5. Wait 7 seconds, then fully depress accelerator pedal and hold for approximately 20 seconds until MIL stops blinking and turns on.
  6. Fully release accelerator pedal within 3 seconds after MIL turns on. Start engine and let it idle. Wait 20 seconds. Quickly depress and release accelerator pedal 2 or 3 times.
  7. Ensure idle speed is 650-750 RPM (A/T in Park or Neutral position) or 650-750 RPM (M/T) and ignition timing is 10-20° BTDC with transmission in Park or Neutral. If idle speed and ignition timing are not as specified, result will be incomplete. Go to next step.
  8. Proceed as follows:
    • Ensure throttle valve is fully closed.
    • Check PCV valve operation.
    • Ensure no vacuum leaks exist.

    If problem is found, repair as necessary. If problem is not found, It may be helpful to perform TROUBLE DIAGNOSIS - SPECIFICATION VALUE. See TROUBLE SHOOTING -- NO CODES article. If engine stalls or idle speed fluctuates, repair cause of condition and repeat procedure.
