There are several pressure switches in a vehicle. The engine has an oil pressure switch that sends a signal to the oil pressure gauge oil or light for you to monitor. Some oil pressure switches can shut down the fuel pump if no oil pressure is detected. The AC system has both a low pressure and a high pressure switch to protect the AC system from self destruction.

Yes. However, the oil pressure switch may be accurate, in which case you have low oil pressure in the engine which can be caused by a faulty oil pump or clogged oil pump screen.
