Help your engine management keep up with power steering demand using the Standard Ignition Power Steering Pressure Switch PSS27. It is a direct-fit replacement for many vehicles, among them the 1998-2001 Nissan Altima, 2000-2004 Nissan Sentra and 1998-2003 Nissan Frontier.

This switch monitors pressure in the power steering system. When pressure rises, such as when the wheel is turned at parking-lot speeds, it signals the engine control system so idle speed can be adjusted for the added pump load.
Signs this part may need replacing include an idle that dips or stalls when steering at low speed, a check engine light, or fluid seeping at the switch. If a failed pressure switch is the cause, PSS27 replaces it.
