Standard Ignition Engine Oil Pressure Switch P/N:PS-158
Standard Motor Products
Standard Ignition PS-326 oil pressure switch for the 1995-2000 Dodge Avenger and other vehicles measures engine oil pressure for the vehicle's data monitoring system.
A low oil level, a worn oil pump or a wiring fault can bring on an oil pressure warning light or an erratic gauge reading just as a failing switch can, so find the cause before replacing the switch. Oil seeping around the switch body is another sign it may need replacing.
The 1995-2000 Chrysler Sebring and the 1991-1999 Mitsubishi 3000GT take this oil pressure switch too, along with many other vehicles, and it is a direct replacement made for OE fit. Open the "Vehicles it fits" section to check your exact model and engine. The engine needs one switch, and this listing is one.
