Duralast Power Steering Pressure Switch PS393

The Duralast line of vehicle electronics is designed for original equipment (OE) form, fit and function for both import and domestic vehicles. The Engine Oil Pressure Sensor/Switch reports engine oil system pressures to the on-board computer, and when oil pressure is low, will illuminate the check engine light. When not replaced, vehicle operators may not be notified of engine oil pressures falling below critical limits. In more advanced vehicles, an unreplaced faulty oil pressure switch or sensor may not notify on-board computers of critical system pressure, thus not allowing the computers to protect the engine from any damage.
