DTC P2102: Throttle Actuator Control Motor Circuit Low; DTC P2103: Throttle Actuator Control Motor Circuit High [08/2013 - ]: Procedure

WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.
  1. INSPECT THROTTLE WITH MOTOR BODY ASSEMBLY (RESISTANCE OF THROTTLE ACTUATOR) 
    1. Inspect the throttle with motor body assembly. Refer to INSPECTION [08/2013 - ] .

      HINT: 

      Perform "Inspection After Repair" after replacing the throttle with motor body assembly. Refer to INITIALIZATION [08/2013 - ] .

    NG → See step   5 

    OK: Go to next step 

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

      Standard Resistance

      Tester Connection Condition Specified Condition
      D15-2 (M+) - D24-60 (M+) Always Below 1 Ω
      D15-1 (M-) - D24-30 (M-) Always Below 1 Ω
      D15-2 (M+) or D24-60 (M+) - Body ground Always 10 kΩ or higher
      D15-1 (M-) or D24-30 (M-) - Body ground Always 10 kΩ or higher

    NG → REPAIR OR REPLACE HARNESS OR CONNECTOR 

    OK: Go to next step 

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

      OK

      No foreign objects between the throttle valve and housing.

      HINT: 

      Perform "Inspection After Repair" after cleaning the throttle with motor body assembly. Refer to INITIALIZATION [08/2013 - ] .

    NG → REMOVE FOREIGN OBJECT AND CLEAN THROTTLE WITH MOTOR BODY ASSEMBLY 

    OK: Go to next step 

  4. INSPECT THROTTLE WITH MOTOR BODY 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 with motor body assembly. Refer to INITIALIZATION [08/2013 - ] .

    NG → See step   6 

    OK → See step   7 

  5. REPLACE THROTTLE WITH MOTOR BODY ASSEMBLY. Refer to  REMOVAL [08/2013 - ] 
  6. REPLACE THROTTLE WITH MOTOR BODY ASSEMBLY. Refer to  REMOVAL [08/2013 - ] 
  7. REPLACE ECM. Refer to  REMOVAL [08/2013 - ]
