I had this issue on my 20.5 gen 4 turbo. It threw code P0116.
I was able to find one of the two wires on that temp sensor had broken right at the male end of the plug.
First time I fixed it I disassembled the connector and soldered the wire back to the cylinder that goes into the plug. This only worked for half a season before it broke again. The wire is super tight in there, there’s not a lot to work with.
I just fixed it again, this time I had some extra 2 plug waterproof connectors laying around that were exactly the same as what that temp sensor uses. Pulled the old male plug off and replaced it while giving me a bunch of extra wire so it’s not as tight and hopefully doesn’t break from vibration again.
New sensor is probably the best solution but both times I’ve fixed it, I was trying to ride the next day, and where it was just a broken wire I didn’t think it was too big of deal
The plug I’m referring to is right behind and to the left of the steering column on the engine.
