Help - Water Temp Reads 112 - Allways


Recommended Posts

My water temp (lake, not engine) is now reading 112 degrees all the time!! When I scroll through all the other displays (time, engine hours, depth, air temp, water temp) is seems to be working fine. I just finished changing the depth gauge module out (under the dash). Any ideas whats happening??

Michael, try to keep up old man. Unless you think the thermostat on his lake water thermometer is stuck open. :Doh:

Gordo, double-check your under dash connections. Could you have loosened something unintentionally or crossed some wires?

Guess I need to check under the dash. Changing out that depth gauge module (under the dash) last weekend should not have affected it, but I may have accidently pulled a wire or connection loose while I was on my back under there!!! Innocent.gif And I tried to be sooooo carefull too!!! ROFL.gif

I think this is about the third thread about water temp stuck at some high number in the past couple of months but I still have never read anything from anyone that has fixed the problem. Mine reads 150 all the time. I'm thinking it is the sending unit but haven't gone to the trouble to replace it yet. That, I think, is a PITA job. I was hoping someone that actually had this problem and fixed it might respond with what they did.

Gordo... are you skiing at a hot spings? I wish my lake water was stuck at half that temp :unsure:

I would think that the sensor has gone bad. Usually you can check by measuring the resistance at different temps. If the resistance from ground to the sensor connection changes when you stick it in hot water then it is probably still good. If no change then it is bad.
