Power Steering Pressure Switch: Service and Repair

REMOVAL
1. Disconnect engine control sensor wiring from Powertrain control module (PCM) and position the engine control sensor wiring out of the way.
2. Directly above engine control sensor wiring, remove ground straps from dash panel.
3. Support engine and transaxle assembly using Rotunda Powertrain Lift 014-00765 and Universal Powertrain Removal Bracket 014-00766 or equivalents. Remove primary steering column boot attachments.
4. Remove steering column gear input shaft coupling retaining bolt and remove steering column intermediate shaft coupling.
5. Remove steering column opening weather seal from inside of passenger compartment.





6. Remove both air suspension height sensor attachments.
7. Remove rear sub-frame-to-body retaining bolts.





8. Remove dual converter Y pipe.
9. Lower Rotunda Powertrain Lift 014-00765 or equivalent carefully until front sub-frame separates from body approximately 100 mm (4 inches).
10. Remove two pins retaining heat shield to bracket and fold shield down.
11. Remove electrical connector from power steering pressure switch.
12. Remove two steering gear-to-crossmember retaining nuts. Remove power rack and pinion steering gear with retaining bolts from crossmember. Tilt power rack and pinion steering gear to gain access to the power steering pressure switch.
13. Remove power steering pressure switch by unscrewing from power steering auxiliary actuator.
