even if u turn wheel slowly u should be able to get 0 volts then flick up to 5 or 7 volts then abck to 0 volts
u can remove sensor from gearbox then spin it by hand
anyway i looked at my diags
the yellow is the signal like u said it should fluctuate as u spin it
the white is ground or 0 volts and it is earthed at the back of the dash inside the cluster
99% of auto elects wont have signal geenerators as they know jack **** bout anything except for fixing door locks on fords or holdens hehehehehe
if u have 12v and an earth and u get no fluctuating voltage on the signal then you have a faulty sensor most probably
you can bench test these sensors its fiddly but u just have to replicate the 3 wires on the speedo sensor plug
Thanks sideshow, i will remove the sensor and check to see if the output signal fluctuates.
