Caution: Unless directed otherwise, the ignition and start switch must be in the OFF or LOCK position, and all electrical loads must be OFF before servicing any electrical component. Disconnect the negative battery cable to prevent an electrical spark should a tool or equipment come in contact with an exposed electrical terminal. Failure to follow these precautions may result in personal injury and/or damage to the vehicle or its components.

Notice: The TP sensor is an electrical component. Do not soak the TP sensor in any liquid cleaner or solvent as damage may result.

Important: If the vehicle is equipped with electronic throttle control (ETC) the throttle position (TP) sensor is NOT serviceable. The throttle body and TP sensor MUST be serviced as a complete assembly.

1. Disconnect the negative battery cable.
2. Remove the generator. Refer to Generator Replacement in Engine Electrical.



3. Disconnect the throttle position TP sensor electrical connector.



4. Remove the TP sensor attaching screws (5).
5. Remove the TP sensor (6).
6. Remove the TP sensor O-ring seal (7).

1. Install the TP sensor O-ring seal (7) on the TP sensor (6).
2. Install the TP sensor on the throttle body with the throttle valve in the closed position. Verify the TP sensor lever lines up with the TP sensor drive lever on the throttle shaft.

Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

3. Install the TP sensor attaching screws (5).

Tighten
Tighten the screws to 2 N·m (18 lb in).




4. Connect the TP sensor electrical connector.



5. Install the generator. Refer to Generator Replacement in Engine Electrical.
6. Connect the negative battery cable.
