The oil pressure sensor works by measuring the amount of oil flow through the engine. The transmitter then sends a signal to the engine control unit (ECU) to indicate the oil pressure. The oil pressure sensor is an important component of the engine, as it helps to ensure that the oil pressure is maintained at the correct level.
