Circuit / System Description
he engine oil pressure (EOP) sensor is mounted in the top rear of the engine. The EOP sensor measures changes in engine oil pressure. The EOP sensor has a 5-volt reference, a ground and a signal circuit. The EOP sensor changes resistance based on engine oil pressure and is used to determine when the oil pressure is below a certain threshold. When the oil pressure reaches a predetermined value, the powertrain control module (PCM) will determine this as low oil pressure. The PCM will then send a serial data message to the Instrument to activate the Check Oil warning icon. When the PCM senses a signal voltage lower than the normal operating range of the sensor, DTC P0522 will set.
