The oil pressure switch is important to the performance and durability of the engine and other parts. It helps by keeping track of the engine oil pressure and alerting you when it is too high or low.
Oil pressure switch operationThe main purpose of the oil pressure switch is to monitor the oil pressure in the vehicle. It also sends data to the combination meter, and if the vehicle has an electronic control module the oil pressure switch will transmit this data to the module. After all the data has been calculated, it will be sent to the instrument panel so that the engine oil pressure warning light can be engaged.
Common problems with a faulty oil pressure switchA faulty oil pressure switch can lead to frequent blinking from the oil pressure light and wrong readings on the oil pressure gauge.
