DTC P0220-15: Throttle/Pedal Position Sensor/Switch "B" Circuit Short to Battery or Open [12/2023 - ]: Procedure
- CHECK HARNESS AND CONNECTOR (THROTTLE POSITION SENSOR - ECM)
Pre-procedure1
- 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 Result C73-4 (VTA2) - C86-89 (VTA2) Always Below 1 Ω Ω C73-5 (VC) or C86-121 (VCTA) - Body ground and other terminals Always 10 kΩ or higher kΩ C73-4 (VTA2) or C86-89 (VTA2) - Body ground and other terminals Always 10 kΩ or higher kΩ Result
Proceed to OK NG
Post-procedure1
- None.
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR
Result:
OK
See step 2
- CHECK TERMINAL VOLTAGE (POWER SOURCE OF THROTTLE POSITION SENSOR)
Pre-procedure1
- Disconnect the throttle body with motor assembly connector.
- Turn the ignition switch ON.
- Measure the voltage according to the value(s) in the table below.
Standard Voltage
Tester Connection Condition Specified Condition Result C73-5 (VC) - C73-3 (E2) Ignition switch ON 4.5 to 5.5 V V C73-4 (VTA2) - C73-3 (E2) Ignition switch ON 3.0 to 5.0 V V Result
Proceed to OK NG
Post-procedure1
- None.
Result:
NG
REPLACE ECM. Refer to REMOVAL [12/2023 - ]
Result:
OK
See step 3
- CHECK HARNESS AND CONNECTOR (RESISTANCE OF ECM)
Pre-procedure1
- Disconnect the throttle body with motor assembly connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition Result C73-5 (VC) - C73-4 (VTA2) Ignition switch off 190 to 210 kΩ kΩ Result
Proceed to OK NG
Post-procedure1
- None.
Result:
NG
REPLACE ECM. Refer to REMOVAL [12/2023 - ]
Result:
OK
See step 4
- READ VALUE USING GTS (THROTTLE POSITION SENSOR NO. 2 VOLTAGE)
Pre-procedure1
- Disconnect the throttle body with motor assembly connector.
- According to the display on the GTS, read the Data List.
Powertrain > Engine > Data List
Tester Display Throttle Position Sensor No. 2 Voltage HINT:
Use the snapshot function to record the value displayed or make a note of it.
Result
Result NEXT
Post-procedure1
- Turn the ignition switch off.
Result:
NEXT
See step 5
- READ VALUE USING GTS (THROTTLE POSITION SENSOR NO. 2 VOLTAGE)
Pre-procedure1
- Connect terminals 3 (E2) and 4 (VTA2) of the throttle body with motor assembly connector on the wire harness side.NOTE:
If the VTA2 terminal voltage or the resistance between VTA2 and E2 is abnormal and terminals 3 (E2) and 4 (VTA2) of the throttle body with motor assembly connector are connected, excessive current may flow through the circuit. In this case, do not connect the terminals.
- Compare the vehicle of the Data List item Throttle Position Sensor No. 2 Voltage after the circuit is shorted to the value when the throttle body with motor assembly connector was connected.
Powertrain > Engine > Data List
Tester Display Throttle Position Sensor No. 2 Voltage Result
Result Proceed to Changes from higher than 4.75 V to less than 2.05 V A Does not change from higher than 4.75 V B
Post-procedure1
- None.
Result:
A
REPLACE THROTTLE BODY WITH MOTOR ASSEMBLY. Refer to REMOVAL [12/2023 - ]
Result:
B
REPLACE ECM. Refer to REMOVAL [12/2023 - ]
- Connect terminals 3 (E2) and 4 (VTA2) of the throttle body with motor assembly connector on the wire harness side.
