P0325 and P0441

[mycargoesvroom]

Any way to trouble shoot these, or any easier fix then replacing the sensors?

P0325 is for the knock sensor. They have a high failure rate on Subarus...best to just replace it.

P0441 is for incorrect EVAP purge flow. There is not any one sensor that you could condemn just off that code. I'd start by checking the integrity of the hoses and steel lines that run from the gas tank to the engine and to the purge valve mounted to the intake.
