- INSPECT THROTTLE POSITION SENSOR
- Disconnect the T1 Throttle Position (TP) sensor connector.
- Measure the resistance between the terminals of the TP sensor.
Standard:
THROTTLE POSITION SENSOR RESISTANCETester Connections Throttle Valve Positions Specified Conditions VC (T1-2)-E2 (T1-1) Between 2.5 kΩ and 5.9 kΩ VTA (T1-3)-E2 (T1-1) Fully closed Between 0.2 kΩ and 5.7 kΩ VTA (T1-3)-E2 (T1-1) Fully open Between 2.0 kΩ and 10.2 kΩ - Reconnect the TP sensor connector.
- NG: REPLACE THROTTLE POSITION SENSOR
- OK: GO TO NEXT STEP
- CHECK HARNESS AND CONNECTOR (THROTTLE POSITION SENSOR - ECM)
- Disconnect the E3 ECM connector.
- Measure the resistance between the terminals of the E3 ECM connector.
