DTC P2102: Throttle Actuator Control Motor Circuit Low; DTC P2103: Throttle Actuator Control Motor Circuit High [12/2015 - 08/2016]: Procedure

WARNING: This page is about a different car, the 2016 Toyota Sienna. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT THROTTLE BODY WITH MOTOR ASSEMBLY (RESISTANCE OF THROTTLE ACTUATOR) 
    1. Inspect throttle body with motor assembly (Refer to INSPECTION [12/2015 - 08/2016] ).

      HINT: 

      Perform "Inspection After Repair" after replacing the throttle body with motor assembly (Refer to INITIALIZATION [12/2015 - 08/2016] ).

    Result: 

    NG 

    REPLACE THROTTLE BODY WITH MOTOR ASSEMBLY 

    (Refer to REMOVAL [12/2015 - 08/2016] )

    Result: 

    OK 

    See step  2

  2. CHECK HARNESS AND CONNECTOR (THROTTLE BODY WITH MOTOR ASSEMBLY - ECM) 
    1. Disconnect the B20 throttle body with motor assembly connector.
    2. Disconnect the B1 ECM connector.
    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection Condition Specified Condition
      B20-2 (M+) - B1-19 (M+) Always Below 1 Ω
      B20-1 (M-) - B1-18 (M-) Always Below 1 Ω
      B20-2 (M+) or B1-19 (M+) - Body ground Always 10 kΩ or higher
      B20-1 (M-) or B1-18 (M-) - Body ground Always 10 kΩ or higher

    Result: 

    NG 

    REPAIR OR REPLACE HARNESS OR CONNECTOR 

    Result: 

    OK 

    See step  3

  3. INSPECT THROTTLE BODY WITH MOTOR ASSEMBLY (VISUALLY CHECK THROTTLE VALVE) 
    1. Check for foreign objects between the throttle valve and the housing.

      OK

      No foreign objects between throttle valve and housing.

      HINT: 

      Perform "Inspection After Repair" after cleaning the throttle body with motor assembly (Refer to INITIALIZATION [12/2015 - 08/2016] ).

    Result: 

    NG 

    REMOVE FOREIGN OBJECT AND CLEAN THROTTLE BODY WITH MOTOR ASSEMBLY 

    Result: 

    OK 

    See step  4

  4. INSPECT THROTTLE BODY WITH MOTOR ASSEMBLY (THROTTLE VALVE) 
    1. Check if the throttle valve opens and closes smoothly.

      OK

      Throttle valve opens and closes smoothly.

      HINT: 

      Perform "Inspection After Repair" after replacing the throttle body with motor assembly (Refer to INITIALIZATION [12/2015 - 08/2016] ).

    Result: 

    OK 

    REPLACE ECM 

    (Refer to REMOVAL [12/2015 - 08/2016] )

    Result: 

    NG 

    REPLACE THROTTLE BODY WITH MOTOR ASSEMBLY 

    (Refer to REMOVAL [12/2015 - 08/2016] )
