DTC P0120-11: Throttle / Pedal Position Sensor / Switch "A" Circuit Short to Ground [06/2020 - 08/2020]: Procedure
WARNING: This page is about a different variant/trim than selected.
- READ VALUE USING TECHSTREAM (THROTTLE POSITION SENSOR NO. 1 VOLTAGE)
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Enter the following menus: Powertrain / Engine / Data List / Throttle Position Sensor No. 1 Voltage.
Powertrain > Engine > Data List
Tester Display Throttle Position Sensor No. 1 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. 1 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 0.56 V to higher than 4.535 V A Does not change from less than 0.56 V B HINT:
Perform "Inspection After Repair" after replacing the throttle body with motor assembly.
Refer to INITIALIZATION [10/2019 - 08/2020]
Result:
A
REPLACE THROTTLE BODY WITH MOTOR ASSEMBLY
Refer to REMOVAL [02/2019 - 08/2020]
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 C15-2 (VC) - C45-109 (VCTA) Always Below 1 Ω C15-1 (VTA) or C45-108 (VTA1) - Body ground Always 10 kΩ or higher Result
Proceed to OK NG
Result:
OK
REPLACE ECM
Refer to REMOVAL [02/2019 - 08/2020]
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
