My '03 Touareg is the 7LA model
With a VR6 3.2L petrol AZZ engine

If i take out the inlet camshaft position hall sender G40

And make shure that it remains connected to
earth (T121a/ 108 at J220 Motronic control unit),
power supply (T121a/ 98 at J220 Motronic control unit) and
signal (T121a/ 86 at J220 Motronic control unit) wires
Arranging that i can probe the wires with a multimeter

With the ignition on, in normal conditions and with a fully loaded battery, does anyone know the voltage i should read

Between earth and power supply
Between earth and signal wire in rest
Between earth and signal wire while metal in front of the hall sender

Please rescue me
