P0522 on Subaru by model: symptoms, diagnosis and fix
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.
Common Symptoms
- oil starvation
- low oil pressure warning
- engine knock
- complete engine failure
- RTV silicone on dipstick
How to Fix
Inspect oil pan/pickup at first oil change for RTV debris. Drop oil pan and clean pickup screen if contamination found. Document with photos for warranty claim. Class action investigation may yield reimbursement.

Frequently asked questions
What does P0522 mean on a 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 it is documented across 1 model: BRZ.
What are the most common causes of P0522?
The most common causes of P0522 are: 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. The specific cause varies by vehicle.
How much does it cost to fix P0522 on a Subaru?
Published repair estimates on Subaru range from $800 to $12,000 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
