it there any way to tell if oil pressure switch is bad other then leaking..will car shut off if oil pressure is low????

The car wont shut off if the oil is low. If the sensor and dash light work, the light will come on, and maybe a chime will sound. They leave the rest up to the driver's descresion.

car will not shut off if oil pressure is low. car will not like low oil pressure, and will tell you by rattling its lifters and knocking. if car has leaking oil pressure switch, replace it. better to fix all oil leaks so oil stays in car.

Hi bobshow, hello everyone,


Assuming you have a light, it tests itself every time you start the engine.

When you turn the switch to the "on" position and see the light, you know the bulb works.

The light goes off while the switch is at the "start" position, and if it stays off when you return it to "run", you know you have oil pressure and that the switch works.

As Andrewk stated above: If it leaks, replace it.
