Throttle Position (TP) Sensor - 3.7L Ti-VCT: Removal

NOTE: The Electronic Throttle Body(ETB) gearbox cleanliness is extremely critical. A single particle the size of a grain of sand can restrict the gear train.

NOTE: Make sure the Electronic Throttle Body(ETB) mounting surface is protected from damage throughout this procedure.

Remove the Electronic Throttle Body(ETB). Refer to Fuel Charging and Controls 3-7L Ti-VCT .
NOTE: Clean the area around where the Throttle Position(TP) sensor and the Electronic Throttle Body(ETB) gearbox mate. The purpose is to eliminate the potential introduction of that dirt into the gearbox when opened.

Prior to Throttle Position(TP) sensor removal, clean dirt and debris from the outside of the gearbox using compressed air, shop towel, nylon brush and metal surface cleaner, as necessary.

NOTE: It is acceptable to support the Electronic Throttle Body(ETB) in a vice only if the mounting surfaces are protected from potential damage.

Support the ETB with the cover facing upward. This will prevent the intermediate gear from falling out during disassembly.

NOTE: If a screw breaks and is stuck in the Electronic Throttle Body(ETB), install a new ETB.

Remove and discard the 4 screws while holding the TP sensor in place.
