Out side temp sensor

[amba]

Dash display has been stuck on 12.5c for most of the day despite being sure it was much colder than that .

Tonight it changed down to 11.5c but this is still a long way off correct

Does this sound like a new sensor is required or can the display be reset some how as have pressed end of steering column stalk but makes no difference.

mine started doing that then went minus then went F
so got new sensor-still F
followed wiring back to multi plug ended up cutting plug off and soldering the wires together NOW fine
But that was my ******* silver shed aka miggy

    I had the same problem. Corrosion of the multiplug teminals is the cause. they can be cleaned but may have to be cut and remade off if severe.
