Keep tabs on your engine's oil pressure with the Standard Ignition Engine Oil Pressure Switch, MPN PS-237. This oil pressure switch is a direct-fit replacement for many vehicles, among them the 1993-1994 Chevrolet Camaro, 1995 Chevrolet Cavalier and 1990-1994 Chevrolet Beretta; see the "Vehicles it fits" section for the full list.
Also called an engine oil pressure sender with gauge, this switch senses oil pressure and signals the dashboard warning light or gauge to report on the lubrication system.
- Function: Reads engine oil pressure and drives the warning-lamp or gauge circuit accordingly.
- Direct-fit: Threads into the oil pressure port on the listed applications.
- Signs it may need replacing: An oil-pressure lamp that stays on or flickers, an erratic or dead gauge, or seepage around the switch body. Diagnose the cause before replacing, since low readings can have other sources.

Frequently Asked Questions
What does this oil pressure switch do?
It senses engine oil pressure and signals the dashboard warning light or gauge, letting you know whether the lubrication system is holding pressure.
Will PS-237 fit my vehicle?
It's a direct-fit replacement for the listed applications, including the 1993-1994 Chevrolet Camaro, 1995 Chevrolet Cavalier and 1990-1994 Chevrolet Beretta. See the "Vehicles it fits" section for the full list.
What are signs this switch may need replacing?
An oil-pressure warning lamp that stays on or flickers, an erratic or non-working gauge, or seepage around the switch body. Diagnose the cause first, since low readings can have other sources.
What numbers does this part interchange with?
It replaces S4077, 8160, OP6665, 10207184, 1643534, 19244511, 22538680, 22542436, 22578692, 22591651 and 24575127.
Does a warning light always mean the switch is bad?
No. If the switch is the cause, replacing it addresses the faulty signal, but a lit lamp can also reflect genuinely low oil pressure, so verify the cause before installing.
