Knock sensors

Hi, does anyone perhaps know of a way to code/flash out of the DME a knock sensor trouble code? I know this is a bad idea but the engine isn't knocking and is healthy, the wiring is the issue to the knock sensor but it won't be a simple wiring fix the entire harness would have to be replaced and I don't have the cash for that now, so looking for a workaround until I can get it fixed properly.

Any input is appreciate, thanks.

It ended up being a stripped wire, even after i had an auto electrician tell me the wiring is "good" and spent A LOT on mechanical parts. Took the whole harness out myself and saw a break in the wiring leading to and from the knock sensor and the DME (specifically 12517619135 the harness for sensor module 1 that plugs into the DME) I guess sometimes you just have to DIY. After I found the break I had a different, much better auto electrician fix the harness up nicely and plugged it back in, no issues now, finally.
