If you're still getting the same trouble code after clearing the computer (PCM) with a scan tool the problem is with the knock sensor circuit, not the knock sensor itself. The wiring may be shorted or the plug for the knock sensor may be damaged. Is the engine knocking or pinging? Especially on acceleration. HTH. -Jim

Always found that a new Subie (or generic Nissan) sensor cures the code; check wiring as suggested above. Even if inoperative the Subie 2.5i will not tend to ping, so don't sweat it.

thanks we had a lot of snow here yesterday and when it clears up I will check out the wiring . After replacing the old sensor with a new one i checked out the sensor I took out and using my multimeter it looked good . so are you refering the wiring on the sensor or the wiring that is coming in from the engine harness ????

The latter. We had our first whiting (not including the election) of 1/4" last night.
