This oil pressure switch is a direct-fit replacement for the 1988-1992 Buick Skylark, 1988-1991 Oldsmobile Cutlass Calais, 1988-1993 Pontiac Grand Am, 1990-1994 Chevrolet Beretta, 1990-1991 Oldsmobile Cutlass Supreme, 1990-1991 Pontiac Grand Prix, 1992-1993 Oldsmobile Achieva, 1993-1994 Chevrolet Camaro, 1993-1994 Pontiac Firebird, and 1995 Chevrolet Cavalier.

An engine oil pressure switch senses oil pressure and signals the dashboard warning light or gauge so you know the lubrication system is doing its job.

  • 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.

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 fixes the signal, but a lit lamp can also reflect genuinely low oil pressure, so verify the cause before installing.
