P0522 on Volvo
Engine Oil Pressure Sensor/Switch Low Voltage
P0522 on Volvo vehicles indicates engine oil pressure sensor/switch low voltage. Au7o has documented this code across 1 Volvo model — most commonly on S60. This code means the engine oil pressure sensor is sending a voltage that is lower than the normal operating range. Depending on how the sensor is wired, this can indicate either a wiring/sensor fault or genuinely low oil pressure. Because low oil pressure can quickly destroy an engine, the actual oil pressure should be verified with a mechanical gauge before assuming it's just an electrical issue. Watch for an oil warning light, ticking noises, or other signs of low pressure. Typical repair costs on Volvo range from $250 to $2,500, depending on the specific model and root cause.
Common Causes of P0522
- •Faulty oil pressure sensor/switch
- •Short to ground or low voltage in the sensor wiring
- •Genuinely low oil pressure or low oil level
- •Corroded or damaged connector at the sensor
- •Poor electrical ground
- •Failing oil pump
- •Use of incorrect oil viscosity

- "No Oil Pressure - Stop Safely" Warning and Oil Pump Pickup Restriction2011-2016
P3-generation S60 owners report a sudden 'No Oil Pressure - Stop Safely' message on the driver information display, often with no prior noise or warning, and frequently while the engine still has oil on the dipstick. CarComplaints lists this as the number-one engine complaint on the 2013 model year. Three root causes account for most cases: a failed or contaminated oil pressure sensor/switch giving a false low reading, sludge and carbon partially blocking the oil pump pickup screen (aggravated by the same oil-consumption and PCV problems these engines suffer), and in the worst cases genuine low pressure from a worn oil pump or bearings. Because the message tells the driver to stop, many owners have the car towed only to be told 'no fault found', which is the classic sensor-failure presentation.

What does P0522 mean on Volvo?▼
P0522 stands for "Engine Oil Pressure Sensor/Switch Low Voltage." This code means the engine oil pressure sensor is sending a voltage that is lower than the normal operating range. Depending on how the sensor is wired, this can indicate either a wiring/sensor fault or genuinely low oil pressure. Because low oil pressure can quickly destroy an engine, the actual oil pressure should be verified with a mechanical gauge before assuming it's just an electrical issue. Watch for an oil warning light, ticking noises, or other signs of low pressure. On Volvo specifically, this code is documented across 1 model.
