Diagnosis Procedure

  1. CHECK THROTTLE POSITION SENSOR POWER SUPPLY 
    1. Turn ignition switch OFF.
    2. Disconnect electric throttle control actuator harness connector.
    3. Turn ignition switch ON.
    4. Check the voltage between electric throttle control actuator harness connector and ground.
      + - Voltage (Approx.)
      Electric throttle control actuator
      Connector Terminal
      F7 2 Ground 5.0 V

      Is the inspection result normal? 

      YES: GO TO  3.

      NO: GO TO 2.

  2. CHECK THROTTLE POSITION SENSOR POWER SUPPLY CIRCUIT 
    1. Turn ignition switch OFF.
    2. Disconnect ECM harness connector.
    3. Check the continuity between electric throttle control actuator harness connector and ground.
      + - Continuity
      Electric throttle control actuator ECM
      Connector Terminal Connector Terminal
      F7 2 F25 80 Existed
    4. Also check harness for short to ground.

      Is the inspection result normal? 

      YES: Perform the trouble diagnosis for power supply circuit.

      NO: Repair or replace error-detected parts.

  3. CHECK THROTTLE POSITION SENSOR GROUND CIRCUIT 
    1. Turn ignition switch OFF.
    2. Disconnect ECM harness connector.
    3. Check the continuity between electric throttle control actuator harness connector and ECM harness connector.
      + - Continuity
      Electric throttle control actuator ECM
      Connector Terminal Connector Terminal
      F7 4 F25 78 Existed
    4. Also check harness for short to power.

      Is the inspection result normal? 

      YES: GO TO 4.

      NO: Repair or replace error-detected parts.

  4. CHECK THROTTLE POSITION SENSOR INPUT SIGNAL CIRCUIT 
    1. Check the continuity between electric throttle control actuator harness connector and ECM harness connector.
      + - Continuity
      Electric throttle control actuator ECM
      Connector Terminal Connector Terminal
      F7 1 F25 79 Existed
      3 77
    2. Also check harness for short to ground and to power.

      Is the inspection result normal? 

      YES: GO TO 5.

      NO: Repair open circuit or short to ground or short to power in harness or connectors.

  5. CHECK THROTTLE POSITION SENSOR 

    Check throttle position sensor. Refer to "COMPONENT INSPECTION (TP SENSOR) ".

    Is the inspection result normal? 

    YES: Check intermittent incident. Refer to "INTERMITTENT INCIDENT ".

    NO: Replace electric throttle control actuator. Refer to "REMOVAL AND INSTALLATION ".
