93 Accord Cooling Fan Issues

ok, my cooling fan has stopped working. no, its not the AC fan. i have gone through the diagnostic in the manual and it leads me to "a broken wire" meaning, im guessing either the power or the ground has been cut or burned through, etc, but one of those wires is no longer connected at some point in the harness. the fan works when i hook it up to the batery, as does the relay, so i know those arent the issues. im guessing it could be the sensor, but i dont want to buy a new sensor if i dont have to. i may try to run a wire from the ecu directly to the power wire of the sensor and then run another wire from the sensor to the relay, and a wire from the realy to the power of the fan, and then ground the fan to the frame. this would essentially go around the broken wire wherever it is. any other creative ideas? does anyone have a sensor they are selling?

Time for a multi-meter. It won't take long to find once you get into it. A Haynes manual would be very helpful for component locations, schematics, and specs.
