The computrons are notorious for failure, be glad it has worked this long.

I can't find that error message in my old service notes anywhere.

Computrons don't do good with moisture, i would unplug all the harness plugs, clean, make sure they are dry, and apply so dielectric grease to the contacts.

At the module itself, remove the control card and clean all the contacts with a new pencil eraser, wipe clean and re-install to see if it clears up that issue.

If you use to have a Atari or Nintendo, remember how you had to blow air onto the contacts if the game didn't work, similar issue with those computrons, they are the Atari of boat computers

My 1993 said shorted wire to sea temp as well this past weekend. I know nothing about the computron system ( Just bought the boat) but plan on checking some wires with a mulit meter this week I will keep you posted on what I find,hopefully the sensor is just shorted.
