Keep tabs on engine oil pressure with the Standard Ignition Engine Oil Pressure Switch (PS-340), a direct-fit replacement for the 1992-1995 Toyota 4Runner, 1993-1995 Toyota Pickup, 1993-1998 Toyota T100, and the 1995 Toyota Tacoma.
Signs this part may need replacing include an oil-pressure warning light that stays on or flickers, an erratic or stuck gauge reading, or oil seeping from the switch body. Because those symptoms can have other causes, confirm the source before replacing — if a failed pressure switch is the cause, this unit replaces it. Verify actual oil pressure with a mechanical gauge if you suspect a genuine low-pressure condition.
Interchange: Manufacturer part number PS-340 (also PS340).
What does the PS-340 oil pressure switch do?
It senses engine oil pressure and switches the dashboard oil-pressure warning light or gauge circuit according to that pressure.
Which vehicles does this switch fit?
It's a direct-fit replacement for the 1992-1995 Toyota 4Runner, 1993-1995 Toyota Pickup, 1993-1998 Toyota T100, and the 1995 Toyota Tacoma. See the Buyer's Guide tab to confirm your vehicle.
What are the signs this switch may need replacing?
A warning light that stays on or flickers, an erratic gauge reading, or oil seeping from the switch body. These symptoms can have other causes, so diagnose before replacing.
How does the switch install?
It threads into the engine's oil-pressure port on the listed applications. Consult the vehicle service information for the correct torque and procedure.
Does a warning light always mean the switch is bad?
No. A lit oil-pressure light can indicate a genuine low-pressure condition. Verify actual pressure with a mechanical gauge; if the switch itself is faulty, this unit replaces it.
