Boost Sensor Replacement Federal Emissions

1. Remove the air cleaner outlet duct. Refer to Air Cleaner Outlet Duct Replacement .
2. Disconnect the boost sensor electrical connector (2).
3. Remove the boost sensor bracket nut (4).
4. Lift the coolant tube (1) off of the stud and move it out of the way.



5. Remove the boost sensor (2) with bracket (1).
6. Remove the sensor from the bracket.
7. Inspect the boost sensor seal for damage, replace as necessary.

1. Position the sensor (2) onto the bracket (1).
2. Install the bracket (with sensor) over the stud.



3. Position the coolant tube (1) over the stud.

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.
