Temperature gauge hasn't been working on my car, so ordered a new sensor from Fiat. Fitted it and it still doesnt work, if I touch the wires on a hot part of the engine the gauge works, but once connected back to the sensor it doesn't work, only moves slightly when ignition turned on. Any ideas, also am getting cam followers adjusted on monday anyone know what a reasonable price would be as garages seem to take advantage of me.

Cheers in advance

mk1 or mk2,engine size/year???

Its a 1996 mk1, 1.1
