Throttle Position Sensor: Service and Repair
Throttle Position (TP) Sensor
Removal
1. Remove the Throttle Body (TB). For additional information, refer to Fuel Charging and Controls - 5.4L (3V) Service and Repair.
2. 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 Throttle Position (TP) sensor.
1. Using a heat gun, apply heat to the top of the Electronic Throttle Body (ETB) until the top TP 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.
2. Monitor the temperature of the top TP sensor bolt ear on the ETB with a digital temperature laser or infrared thermometer, while heating the ETB.
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.
