    hi guys
    had bmw e46 in yesterday with abs/esp lights on.code read on launch,n/s/f wheel sensor came up as fault.went to scope signal but found three wire abs sensor instead of 2 wire i am used to seeing,approx 2.5 volts on 2wires[sensor connected]earth on third, spun wheel, no output. sensor disconnected,2.5 volt feed from ecu on 1 wire,nothing on other 2.
    ran out of time last night but will scope o/s/f sensor today but wondered if anyone ever come across these sensors or know voltages/scope traces etc.
    thanks guys.
