Detailed Product Overview

Standard Ignition PSS20 is a power steering pressure switch used to monitor steering system pressure and relay that signal to the vehicle control system. In Nissan Frontier, TITAN, GT-R, 370Z, Armada, Altima, Maxima, Murano, Pathfinder, Xterra, and select INFINITI models, this switch supports proper steering system operation by matching the original screw-in, plug-in design. The PSS20 is a direct-fit style replacement for applications that use a 3-terminal blade connection and a female connector at the switch.

This part cross-references Dorman - OE Solutions 926-455 and Beck/Arnley 201-2370 for the same application.

Common Problems This Part Can Address

• Power steering warning light or steering-related fault codes
• Erratic idle behavior when steering load changes
• Loss of steering pressure signal to the control system
• Harder steering feel caused by a failed pressure switch circuit
• Intermittent electrical connection at the steering pressure switch

Installation Notes and Tips

Install the switch in the engine bay at the original mounting location and verify the connector style before installation. Because wiring is not included, reuse the existing harness connection and inspect the terminals for corrosion, looseness, or damage before plugging in the new switch. Confirm the vehicle uses the screw-in style pressure switch and, on applicable Sentra models, the switch mounts to the power steering pump.

Quality Assurance

Standard Ignition replacement parts are built to match OE-style fitment and electrical connection requirements for service work on Nissan and INFINITI steering systems.
