Removal Procedure
- Remove the air conditioning (A/C) compressor. Refer to Air Conditioning Compressor Replacement in Heating, Ventilation, and Air Conditioning.
- Disconnect the fuel rail sensor (1) electrical connector.
- Prior to removal, clean the function block and fuel pressure sensor thoroughly with solvent, such as GM P/N 12377981 (Canadian P/N 10953463) or equivalent.
- Using compressed air, thoroughly blow dry the block and sensor.
- Remove the sensor and metal gasket from the function block. Discard the gasket.
Installation Procedure
- Install the sensor and a NEW metal gasket to the function block.
- If the crows foot is kept perpendicular (90 degrees) to the torque wrench during the entire tightening procedure, then the torque wrench can be set to the listed torque specification.
- Connect the sensor (1) electrical connector.
- Install the A/C compressor. Refer to Air Conditioning Compressor Replacement in Heating, Ventilation, and Air Conditioning.
If a crows foot is used to torque the sensor then special attention to the position of the crows foot in relation to the torque wrench is required.
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.
Tighten
Tighten the sensor to 70 N·m (52 lb ft).
