    2002 honda aquatrax f12x help SOS ecm knock sensors or wiring harnes

    I have a 2002 honda aquatrax with about 40hrs on it started throwing knock sensor code after riding for a hour. I ordered a ecm from schredder here and ran the ski for about 2 hours throws knock sensor code agin I have previously changed the knock sensor before so I am having a hard time to believe it is bad knock sensor since it doesn't throw the code right away besides the code the ski runs great. So where my question is where do I go next knock sensor or wiring or is it possible the ecm still could be bad since it was a used one. I have noticed the turbo is hot to touch after riding but I don't think this is a turbo over heat issue if it throwning a knock sensor code. Any help would be greatly appreciated. Thank you

    Check your wire harness from ecu plug back to sensor inspect for rubbing chaffing don't know the dude you bought ecu from do you have access to another ski to test ecu?

    I do not have another ski to trade ecu with wish I did but don't. Where would the harness be bad?

    don't know do you know how to use a ohm meter? its a single wire back to ecu plug if the wire is bad or has rubbed somewhere this will trigger a code provided the ECU and the sensor were good
