Idle Air Control Motor

  1. To check idle air control motor resistance, disconnect connector at idle air control motor. Idle air control motor is mounted on throttle body and contains a 6-pin Black connector.
  2. Install Test Harness (MD998463) on idle air control motor. Using ohmmeter, check resistance between terminals No. 1 (Red clip) and No. 2 (White clip) on test harness and then between terminals No. 2 (White clip) and No. 3 (Blue clip) on test harness. Perform STEP 1. See Fig 1 . Resistance should be 28-33 ohms at 68°F (20°C).
  3. Using ohmmeter, check resistance between terminals No. 4 (Black clip) and No. 5 (Green clip) on test harness and then between terminals No. 5 (Green Clip) and No. 6 (Yellow clip) on test harness. Perform STEP 2. See Fig 1 . Resistance should be 28-33 ohms at 68°F (20°C).
  4. If resistance is within specification, go to next step. If resistance is not within specification, replace idle air control motor.

  5. To check idle air control motor operation, remove idle air control motor from throttle body. Install Test Harness (MD998463) on idle air control motor.
  6. Connect positive terminal of a 6-volt battery to White and Green clips on test harness. See Fig 2 .
  7. Connect negative terminal of 6-volt battery to specified clips on test harness in proper sequence. See IDLE AIR CONTROL MOTOR GROUNDING SEQUENCE table. See Fig 2 .
    IDLE AIR CONTROL MOTOR GROUNDING SEQUENCE

    Sequence Clips On Test Harness
    Step 1 Red & Black
    Step 2 Blue & Black
    Step 3 Blue & Yellow
    Step 4 Red & Yellow
    Step 5 Red & Black
    Step 6 (1) *
    (1) Repeat step 5 back to step 1 in sequence.
  8. When connecting negative terminal to specified clips on test harness, idle air control motor should operate. A slight vibration will exist at idle air control motor and the pintle on idle air control motor should move.
  9. Replace idle air control motor if defective. Remove test harness. Reinstall idle air control motor.
