Check engine light P0720

[Fummins]

I got a car that was just started and the engine light came on. The only code I see is P0720-output speed sensor circuit. No abs or traction control lights are on. I tried to clear the light but no dice. Car only has 77000kms on it. I really don't want to take it dealer cause they're slower than the second coming of Christ but that's what warranty is for I guess. Figured I'd see if anyone else had this code. It's -20c/-4F here and cold weather seems to bring out all the problems.

Edit:Light is now out but code is still stored. My scanner can only read the engine codes so I can't clear or read the tcm codes. It works fine with 2017 Nissans though.
