Where is the oil pressure sending switch located?

engine block
The oil pressure switch is usually located on the engine block, often near the oil filter, and warns the driver whenever the oil pressure gets too low by illuminating a red oil light in the instrument cluster. Some vehicles use an oil pressure gauge in place of, or in addition to, a red oil light.

How do you know if your oil pressure switch is bad?
