Removal Procedure
- Remove the throttle body. Refer to Throttle Body Assembly Replacement .
- Remove the mounting screws from the TP sensor.
- Remove the TP sensor from the throttle body assembly.
Notice: The TP sensor is an electrical component. Do not soak the TP sensor in any liquid cleaner or solvent, as damage may result.
Installation Procedure
- Place the TP sensor over the throttle shaft and align the TP mounting holes with their corresponding holes in the throttle body assembly.
- Install the TP sensor mounting screws.
- Install the throttle body. Refer to Throttle Body Assembly Replacement .
- Connect the TP sensor harness connector.
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.
Important: The screws used to attach the TP sensor are coated with thread locking adhesive. Clean the attaching screw threads and apply thread locking material GM P/N 1052624 or equivalent.
Tighten
