    Yes, you can test it. Kind of like testing a TPS, where it is good to use an analog volt meter to make sure the sweep of the output voltage is 'smooth' and no dead spots through the sweep of the door. Here is a page that should help troubleshooting yours.

      unplug the VAM. the ECC will use default values, that will at least allow it to run.

          I see the voltage values but it does not say which pins to measure from

            Pin 43 (VAF sig) is the voltage you want to measure and compare to the table, which shows as a white w/black stripe wire in my EVTM. You can connect your negative lead to either chassis ground or Pin 46 (Sig Rtn), which should be a black w/white stripe wire. Pin 26 (Vref) should give you 5 volts.
