At Ford, we refer to them as Active and Passive. Passive sensors are tested with an OHM meter and can be tested to see if they produce AC voltave (in milivolts) and Active require a 12V power source and are tested in AMPS. Your meter has to be wired in series with the negitive lead from the sensor to the module and the positive wire has to be complete with the key on. The signal should toggle from 7mA to 14mA. If you are in Charlotte NC week after next, I am teaching Advanced Brakes.
