P0522 on Subaru
Engine Oil Pressure Sensor/Switch Low Voltage
P0522 on Subaru vehicles indicates engine oil pressure sensor/switch low voltage. Au7o has documented this code across 1 Subaru model — most commonly on BRZ. 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 Subaru range from $800 to $12,000, 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

- FA24 Excessive RTV Sealant Clogs Oil Pickup - Engine Failure2022-2024
Owners of 2022+ BRZs are finding excessive RTV silicone sealant from the factory oil pan and timing cover assembly migrating into the oil system, clogging the oil pickup screen and starving the FA24 of oil. Sealant has been found on dipsticks at as few as 500 miles; multiple complete engine failures have been documented (one at 5,498 miles). Subject of an active class action investigation by Sauder Schelkopf and Lemberg Law.

What does P0522 mean on Subaru?▼
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 Subaru specifically, this code is documented across 1 model.
What causes P0522 on Subaru vehicles?▼
Common causes on Subaru: 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. Specific causes vary by model and year — see the per-model sections below.
How much does it cost to fix P0522 on a Subaru?▼
