Throttle Position Sensor: Service and Repair

Throttle Position (TP) Sensor

Removal

1. Remove the Charge Air Cooler (CAC) outlet pipe.

2. Disconnect the Throttle Position (TP) sensor electrical connector.





3. NOTICE: Do not put direct heat on the Throttle Position (TP) sensor or any other plastic parts because heat damage may occur. Damage may also occur if Electronic Throttle Body (ETB) temperature exceeds 120°C (248°F).

NOTE: Do not use power tools.
Remove the TP (Throttle Position) sensor.

1. Using a suitable heat gun, apply heat to the top of the Electronic Throttle Body (ETB) until the top TP (Throttle Position) sensor bolt ear reaches approximately 55°C (130°F), this should take no more than 3 minutes using an 1,100-watt heat gun. The heat gun should be about 25.4 mm (1 in) away from the ETB (Electronic Throttle Body).

2. Monitor the temperature of the top TP (Throttle Position) sensor bolt ear on the ETB (Electronic Throttle Body) with a suitable temperature measuring device, such as a digital temperature laser or infrared thermometer, while heating the ETB (Electronic Throttle Body).

3. Using hand tools, quickly remove the bolt farthest from the heat source first and discard.

4. Using hand tools, remove the remaining bolt and discard.

5. Remove and discard the TP (Throttle Position) sensor.






Installation

1. NOTE: When installing the new TP (Throttle Position) sensor, make sure that the radial locator tab on the TP (Throttle Position) sensor is aligned with the radial locator hole on the ETB (Electronic Throttle Body).

NOTE: Do not use power tools.

Install the new TP (Throttle Position) sensor.
- Using hand tools, install the 2 new bolts.
- Tighten to 3 Nm (27 lb-in).





2. Connect the TP (Throttle Position) sensor electrical connector.





3. Install the CAC (Charge Air Cooler) outlet pipe.
