P0341 on a Subaru: Causes, Fixes & Repair Cost

🟠 Moderate severity · drivable

You can usually keep driving a Subaru with P0341, but rough idle or stalling is possible, so get it checked soon.

What P0341 means on a Subaru

On a Subaru, P0341 means the engine computer sees a camshaft position signal from bank 1 that is outside the expected range. Subaru boxer engines use cam sensors to time fuel and ignition, and the code often shows up with a rough idle or hard start. A failing sensor, wiring trouble, or worn timing parts can all cause the reading to drift.

Is P0341 common on Subarus?

P0341 is common on Subaru models with the 2.5L boxer engine as the camshaft position sensors age. Oil leaking into the sensor area and aging timing components are typical on higher-mileage Outbacks, Foresters, and Imprezas. The code can come and go depending on engine temperature.

Commonly reported on: Outback, Forester, Impreza, Legacy.
