What Is Code P0520? Fault code P0520 is defined as “Engine Oil Pressure Sensor/Switch – Circuit Malfunction.” It’s a Diagnostic Trouble Code (DTC) indicating problems with the vehicle’s oil pressure sensor, oil pressure switch, or actual oil pressure.
What could cause a P0520 code?
P0520 is a OBD-II generic code for threshold issue with the oil pressure sensor. If the engine computer reads a signal from the sensor that is either too high or too low in relation to the manufacturer’s parameters, a P0520 will be triggered.
Where is the low oil pressure sensor located?
According to Repair Pal, the oil pressure sensor is usually located near the bottom, right side of the engine, between the oil filter and the oil pan.
How much does it cost to replace an oil pressure sensor?
The average oil pressure sensor replacement cost is between $50 and $250, depending on the car model and labor costs. An oil pressure sensor costs $30 to $100, and the labor costs $20 to $150.
Where is the oil pressure sending switch located?
The oil pressure switch is usually located on the engine block, often near the oil filter, and warns the driver whenever the oil pressure gets too low by illuminating a red oil light in the instrument cluster.
Can you drive with a faulty oil pressure sensor?
No. It is not safe driving with a bad oil pressure sensor. It will often cause your check engine light to illuminate, even though there isn’t necessarily anything wrong with your car. Or worse, it won’t trigger any warning when in fact your engine runs low on oil, damaging its internal parts.
How do I know my oil pressure sensor is bad?
The best way to test if your sensor is bad is through the lights on the oil pressure gauge. If the low oil pressure warning light comes on when they engine’s oil levels are normal and your engine is running smoothly and quietly, then you likely have a bad oil pressure sensor.
How do you reset the oil pressure sensor?
Depress the gas pedal slowly three successive times within 10 seconds. At this point, the system should have reset. You can verify by turning the ignition off and then on again. If the light is still on, repeat the process.
What happens when your oil pressure sensor goes out?
When your oil pressure sensor is about to fail, the Low Oil light will blink on and off. This can be quite frightening to a car owner since low oil could cause significant damage to an engine. Continually checking your engine oil is not only time consuming but also stressful.
