Q:IS THIS SWITCH NORMALLY OPEN OR NORMALLY CLOSED ??
BOB H.
A:BEST ANSWERHi Bob,
The oil pressure switch sends a signal directly to the driver's instrument panel or the engine control module. They are usually normally closed switches; this is why the warning light illuminates when the ignition switch is first turned on and goes out after the engine starts and oil pressure rises.
Still, please refer to a vehicle specific repair service manual for accurate information on the functionality about this part. Show less

P0521 Code: Engine Oil Pressure Sensor/Switch Range/PerformanceA vehicle’s oil pressure sensor is typically a three-wire sensor with 5 volts, a signal return ground, and a signal voltage that varies with engine oil pressure. The sensor’s job is to detect and report engine oil pressure to the PCM. The OBD-II code P0521 is triggered when the PCM
P0523 Code: Engine Oil Pressure Sensor/Switch “A” Circuit HighThe PCM monitors engine oil pressure with the help of the Engine Oil Pressure sensor. The P0523 code is typically logged when the PCM receives high readings from this sensor. This code belongs to a range of diagnostic trouble codes that refer to oil pressure problems. Related DTCs include P0520,
P0522 Code: Engine Oil Pressure Sensor/Switch “A” Circuit LowThe pressure-sensing mechanism in the oil pressure switch is in direct contact with the oil gallery. This means that any changes in gallery oil pressure will produce an increase or decrease in the resistance of the oil pressure transducer.
Where Is the Oil Pressure Switch Located?The oil pressure switch monitors the oil pressure and illuminates the warning light or the oil pressure indicator when the pressure falls below a certain threshold. It also notifies you when the pressure becomes too high. This typically only happens when the oil pump relief valve is stuck closed. Low
P0520 Code: Engine Oil Pressure Sensor/Switch “A” CircuitInside the oil pressure switch is a pressure-sensing device that’s in direct contact with the oil flow. Oil pressure can either increase or decrease the sensor’s resistance and the PCM is capable of converting these changes into an accurate interpretation of the actual oil pressure.
