The PSP switch is located on the power steering pressure hose, above the right end of the steering gear assembly. Begin by raising the front of the vehicle and securing it on jackstands. Next, disconnect the electrical connector from the PSP switch. Using a wrench along with a back-up wrench to protect the power steering line from kinking, unscrew the PSP switch, ensuring to have a pan ready to catch any leaking power steering fluid. Installation follows the reverse order of removal. Finally, check the power steering fluid level and add the appropriate type of fluid if necessary.
