I can't get my head around this car with a simple cam sensor fault "DF116" (no cam signal. So I scoped the three terminals and my results were as follows...
Pin 1 ground. (I checked it's integrity by grounding my test light through it).
Pin 3 Battery volts. I checked that with a test lamp and found it OK
Pin 2 signal. 8v flat line while cranking with the scope.
This sensor is actually on the HP pump pulley and you can physically see the cast protrusion that passes the sensor.
I took the sensor out and passed the shaft of a screw driver past it which in my experience is enough to trigger a response from a hall sensor and still nothing, so I condemned the sensor.
Purchased a new Facet sensor and I have exactly the same results.
So for some homework I connected the original sensor up to a breadboard juiced it up and tried to make it switch (which it did ever so slightly) so do I have duff "new" sensor?

Another thought, is the sensor close enough to the trigger on pulley?
