Designed to help engine idle keep pace with steering load, the Standard Power Steering Pressure Switch PSS26 senses pressure in the power steering system and signals the engine's control system. It fits many vehicles, among them the 2002-2003 Jeep Liberty, 1996 Dodge Grand Caravan and 1996 Chrysler Town & Country, as a direct-fit replacement for the listed applications. See the Buyer's Guide tab for the full list and engine details.
When a power steering pressure switch fails, the engine may not get the signal it needs as steering load rises. Signs this part may need replacing include idle dipping or stalling when turning the wheel at low speed, or fluid seeping around the switch. Diagnose the cause before replacing, since other faults can produce similar symptoms.
