Well twice this month I've thrown a knock sensor CEL. I have an 02 2.5RS with about 50K miles. Anyone know if this is a common problem? I was told this is one of the sensors that typically go bad on subarus. Should I just replace the sensor and see if it throws a CEL again? Any help appreciated.
I'm not completely certain, but I have an extra knock sensor off of my '04 WRX you can try out. I'm pretty sure that the RS/WRX ones are the same part. pm me if you want to negotiate something. - tom EDIT: I just checked mine, and the part number is 22060AA100
Cool, I'll check tomorrow at work to see if its the same part #. I have one from my EJ22T as well but I'm pretty sure that one is different because its 10 years older.
