• Q: How to service the Throttle Position Sensor on a 4.6L (3V) engine on 2007 Mercury Mountaineer?

  A: Vehicle models with 4.6L (3V) engines require service of the Throttle Position (TP) Sensor which begins by deleting the air cleaner outlet pipe and removing the bolts that fasten the heated positive crankcase ventilation (PCV) fitting followed by setting everything aside. Starting the project requires you to remove the O-ring seal then disconnect the TP sensor electrical connection. The technician should start by loosening TP sensor screws 1-2 full turns with a hand tool followed by using a suitable high-speed driver to finish removal because incorrect screw removal damages them. Insert a new TP sensor and two screws into the throttle body while matching the radial locator tab to its radial locator hole before tightening the screws to 3 Nm (27 lb-in). Follow these steps to tighten the TP sensor electrical connector after securing its screws at 3 Nm (27 lb-in). The repair of vehicles with 4.6L (3V) engines requires new O-ring seals together with correct placement of the heated PCV fitting followed by securing it with bolts before installing the air cleaner outlet pipe.
