check the wires from the ecu to the knock sensor. if your timing is way out or you have mechanical noise in the engine it can set this code also

I would run a wire from the knock sensor directly to the ECU's pin location and see if that solves it, if it does then you know the problem is in the wiring

Doesn't have to go through to firewall or anything crazy...just the quickest way to check the wire without snatching out the multi-meter.

Did you replace it with a new one or just one you or a buddy had laying around?
