July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Learning Procedure Without CONSULT-II

  1. Perform ACCELERATOR PEDAL RELEASED POSITION LEARNING  . Perform THROTTLE VALVE CLOSED POSITION LEARNING  . Start engine and warm to normal operating temperature.
  2. Ensure all conditions under PRE-CONDITIONING  are met. Turn ignition off and wait at least 10 seconds. Ensure accelerator pedal is fully released.
  3. Turn ignition on and wait 3 seconds. Fully depress and fully release accelerator pedal quickly 5 times within 5 seconds. See Fig 1 .
  4. Wait 7 seconds, then fully depress accelerator pedal and hold until MIL stays on (it will take about 20 seconds).
  5. Fully release accelerator pedal within 3 seconds after MIL stays on. Start engine and let it idle. Wait 20 seconds. Quickly depress and release accelerator pedal 2 or 3 times.
  6. Ensure idle speed is 600-700 RPM and ignition timing is 10-20 degrees 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.
  7. 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.
