2. Disconnect the dual function pressure switch and boost pressure transducer connectors.





3. Use special tool # 6607 to remove the dual function pressure switch from the actuator housing. Using special tool # 6684, remove the boost pressure transducer from the actuator housing (Figure 3).

4. Install the boost pressure transducer into the actuator housing and torque to 9 - 14 N-m (80 - 124 in.lbs.). Install the dual function pressure switch and torque to 9 - 14 N-m (80 - 124 in.lbs.).

5. Connect the dual function pressure switch and the boost pressure transducer connectors.
