P0325 Engine Error Code on 2003 PT Turbo

[intim3]

Hi everyone. For months now I have been getting the same error message off and on. I checked it and it came out to be a "P0325" engine light error. I looked-up this code on the error code list in the forum and it says that it is a knock sensor error. I have tried to disconnect the battery but it came back. I see or notice no difference in the car running or anything. Most of the time, the light will come-on during a run and maybe stay on for a 2 days or so and then go off again for maybe a week or two. From experience, do any readers think this is actually the knock sensor gone bad or maybe the spark plugs and/or the spark plug wires need changing? The car is stock except for a Mopar BOV and Airaid cold air intake. It is a 2003 GT Turbo. Hope to hear from anyone with any good ideas. Thanks in advance.
