The oil sender, or oil pressure switch, is mounted in the oil circuit of the engine. It monitors oil pressure and turns on or off a warning light or checks an oil pressure gauge. The oil pressure switch is normally closed.

The oil pressure warning light comes on when the vehicle's ignition is turned on. When oil pressure builds up while the engine is running, the oil pressure switch opens and the ground contact for the warning light is cut. The warning light turns off.

The oil sender will not work in cases such as clogged inlet hole, contact failure in connector, internal short circuits, damaged measuring element and loss of sealing. In case of non-operation, the warning light turns on constantly or does not come on at all, the oil pressure indicator does not work, or there are oil leaks.

In this case, connectors and cables need to be checked for proper seating or damage, the enclosure must be checked for leaks, or the motor connections and switch flange must be checked for contamination.

In short, an oil pressure switch (oil sender) is a protection equipment for the engine. It is a kind of oil pressure sensor. Most mechanical and conventionally protective oil switches close when activated to indicate low oil pressure. When an engine is not running, there is no oil pressure and therefore the low oil pressure switch is active, this should change once the engine has run for a few seconds.
