P0521 Code: Engine Oil Pressure Sensor/Switch Range/Performance
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 High
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 Low
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?

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.
