P0524 on Subaru
Engine Oil Pressure Too Low
P0524 on Subaru vehicles indicates engine oil pressure too low. Au7o has documented this code across 1 Subaru model — most commonly on WRX STI. This code sets when the engine control module sees that engine oil pressure has dropped below the safe minimum threshold, based on the reading from the oil pressure sensor (or switch). Adequate oil pressure is what keeps a protective film of oil between the bearings, crankshaft, and other moving parts, so the computer treats low pressure as a serious warning. It can mean the actual pressure really is too low, or that the sensor circuit is reporting a false low value. Because true low oil pressure can quickly destroy an engine, this code should be checked immediately and the engine not run hard until the cause is confirmed. Typical repair costs on Subaru range from $200 to $3,500, depending on the specific model and root cause.
Common Causes of P0524
- •Low engine oil level
- •Faulty oil pressure sensor or sending unit
- •Worn or failing oil pump
- •Clogged oil pickup screen or dirty oil
- •Wrong oil viscosity for the engine
- •Worn engine bearings reducing pressure
- •Wiring or connector fault at the oil pressure sensor

- Oil Starvation During Hard Cornering (EJ257 Boxer Engine)2004-2021
The EJ257 boxer engine uses a shallow oil pan design that is prone to oil starvation during sustained high-G cornering, particularly on track days or aggressive canyon driving. The flat-four layout means oil sloshes away from the pickup tube during lateral loading, starving rod and main bearings of lubrication. This is a leading cause of spun rod bearings and catastrophic engine failure on STIs used for motorsport or spirited driving.

What does P0524 mean on Subaru?▼
P0524 stands for "Engine Oil Pressure Too Low." This code sets when the engine control module sees that engine oil pressure has dropped below the safe minimum threshold, based on the reading from the oil pressure sensor (or switch).

It can mean the actual pressure really is too low, or that the sensor circuit is reporting a false low value. Because true low oil pressure can quickly destroy an engine, this code should be checked immediately and the engine not run hard until the cause is confirmed. On Subaru specifically, this code is documented across 1 model.
