Keep an accurate read on engine oil pressure with the Standard Ignition Engine Oil Pressure Switch PS-144 — a direct-fit replacement for a wide range of 1979–1986 GM cars, trucks, vans, and SUVs. This switch threads into the engine's oil-pressure port and controls the circuit to the dashboard oil-pressure gauge or low-oil-pressure warning lamp, so the driver gets a reliable signal about the engine's oiling system.
What it does: Senses engine oil pressure and opens or closes the electrical circuit to the gauge or warning light based on the pressure at the port.

What does this oil pressure switch do?
It senses engine oil pressure at its port and opens or closes the circuit to the dashboard oil-pressure gauge or warning lamp, giving the driver a signal about the engine's oiling system.
What are the signs my oil pressure switch may need replacing?
A gauge reading incorrectly, a flickering or constantly-lit oil warning light, or no reading at all. Diagnose first — low actual oil pressure and wiring faults can cause the same signs.
Will this fit my vehicle?
It fits many 1979–1986 GM applications, including Chevrolet C/K trucks, Caprice, Impala, GMC C/K trucks and Jimmy, plus select Buick, Oldsmobile, and Pontiac models. Check the Buyer's Guide tab for the full list.
What numbers does the PS-144 interchange with?
It cross-references S695, 8122, 2-8122, 28122, PS134, OP6632, 14034354, 1403454, 15663139, 15665282, and 25036214.
Does replacing this switch fix a low oil pressure warning?
Only if a faulty switch is the cause. The same warning can come from genuinely low oil pressure or a wiring problem, so confirm the source before replacing the switch.
