Cant seem to get cam signal on ecumaster black. its a hall sensor 1 tooth pattern from volvo 850/960. Harness does give pin 1 12v, pin 2, 5v pin 3 ground and when connected with sensor pin 2 gives 11.5V no matter if the sensor is activated or not. Fiddled with settings (Pullups, trigger edge) but almost nothing, only when i put input filter to high it gives signal for a second and then disappears again.

so it cant be with the ecu settings right? Could there be a wiring problem or some signal interfering?
