DTC P0220-11: Throttle/Pedal Position Sensor/Switch "B" Circuit Short to Ground [08/2021 - ]: Procedure
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Lexus ES 300h, 2023 Lexus ES 300h, 2022 Lexus ES 300h, 2021 Lexus ES 300h, and 2020 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.
- READ VALUE USING TECHSTREAM (THROTTLE POSITION SENSOR NO. 2 VOLTAGE)
- Connect the Techstream to the DLC3.
- Turn the power switch on (IG).
- Turn the Techstream on.
- 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 - Read the values displayed on the Techstream.
- Disconnect the throttle body with motor assembly connector.
- 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 [08/2021 - ]
Result:
A
REPLACE THROTTLE BODY WITH MOTOR ASSEMBLY. Refer to REMOVAL [06/2018 - ]
Result:
B
See step 2
- CHECK HARNESS AND CONNECTOR (THROTTLE POSITION SENSOR - ECM)
- Disconnect the throttle body with motor assembly connector.
- Disconnect the ECM connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition C57-2 (VC) - C88-109 (VCTA) Always Below 1 Ω C57-3 (VTA2) or C88-87 (VTA2) - Body ground Always 10 kΩ or higher Result
Proceed to OK NG
Result:
OK
REPLACE ECM. Refer to REMOVAL [08/2021 - 09/2022] , or refer to REMOVAL [09/2022 - ]
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
