DTC P0220-11: Throttle/Pedal Position Sensor/Switch "B" Circuit Short to Ground [10/2017 - ]: Procedure

  1. READ VALUE USING TECHSTREAM (THROTTLE POSITION SENSOR NO. 2 VOLTAGE) 
    1. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG).
    3. Turn the Techstream on.
    4. Enter the following menus: Powertrain / Engine / Data List / Throttle Position Sensor No. 2 Voltage.

      Powertrain > Engine > Data List 

      Tester Display
      Throttle Position Sensor No. 2 Voltage
    5. Read the values displayed on the Techstream.
    6. Disconnect the throttle body with motor assembly connector.
    7. Compare the value of the Data List item Throttle Position Sensor No. 2 Voltage after disconnecting the throttle body with motor assembly connector to the value when the connector was connected.

      Result

      Result Proceed to
      Changes from less than 2.05 V to higher than 4.75 V A
      Does not change from less than 2.05 V B

      HINT: 

      Perform "Inspection After Repair" after replacing the throttle body with motor assembly.

      Refer to INITIALIZATION [10/2017 - 09/2018] , or refer to INITIALIZATION [09/2018 - 09/2020] , or refer to INITIALIZATION [09/2020 - ]

    Result: 

    REPLACE THROTTLE BODY WITH MOTOR ASSEMBLY. Refer to  REMOVAL [10/2017 - 09/2020]  , or refer to  REMOVAL [09/2020 - ] 

    Result: 

    See step  2

  2. CHECK HARNESS AND CONNECTOR (THROTTLE POSITION SENSOR - ECM) 
    1. Disconnect the throttle body with motor 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
      F21-5 (VC) - F102-121 (VCTA) Always Below 1 Ω
      F21-4 (VTA2) or F102-89 (VTA2) - Body ground Always 10 kΩ or higher

      Result

      Proceed to
      OK
