Acura TL Power Steering Pressure Switch

The computer's indication of a spike in steering effort allows the Acura TL Power Steering Pressure Switch to ensure smooth engine performance during close maneuvers. The Power Steering Pressure Switch is located in the high-pressure line, which detects increasing hydraulic force when the driver turns the steering wheel at low speed. Subsequently, it sends a signal to the ECU to bump idle speed. In effect, this prevents the pump load from stalling the motor. The earlier Acura TL models incorporated an on-off Power Steering Pressure Switch that closed at a preset pressure. Later models matched the switch with electronically controlled pumps that varied with vehicle speed data for more sophisticated variable assist. This Power Steering Pressure Switch provides comfort and reliability throughout the Acura lineup. It is a diaphragm-operated pressure switch that reverses an internal electrical contact when fluid pressure is applied. The switch activates only while parked or during low-speed turns. At highway speeds, the switch is inactive to retain the driver's natural feel of the road. The owners in the TL community appreciate the unassuming way in which this Power Steering Pressure Switch helps make the car more drivable on an everyday basis.

We provide a broad range of OEM Acura TL Power Steering Pressure Switch at unbeatable prices on our website. For your OEM parts, You can count on the guaranteed quality, manufacturer's warranty, outstanding customer service, and prompt delivery. We look forward to your visit.

Acura TL Power Steering Pressure Switch Parts Questions & Experts Answers

  • Q: Where is the Power Steering Pressure Switch Located and How to Remove and Install on Acura TL?
    A:
    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.
