P0325 Knock Sensor issue CL9

[jjman]

sounds like it could actually be a genuine knock event then. have you considered-
fuel quality in your area? (you are already using 95 octane+?)
excessive carbon build up in the motor?

That's what I've been told...unfortunately. I have a feeling it might be something to do with that, because I've stupidly been letting my tank run to basically empty a lot before re-filling recently, you reckon' something might've got in? I always use 98, don't think it could be carbon build up.

Sadly carbon build up doesn't really have much to do with what fuel you use.

The k24 engines in hondas actually does carbon up.... a lot.

Oh nah I didn't mean that it was related to that haha.
And thanks @amant02 I get most of that stuff done but yeah I'll be sure to get more intensive this time.

yeah carbon build up increases the compression ratio as well as making the combustion equation not as balanced- hence leading to knock. though if you have been using 98 then that could be ruled out unless you live in a 'stan. 98 is plenty if not overkill...
