Can XG350 crank and cam position sensors be tested with multimeter or scope?

    XG350 ran 50 miles after new timing belt installed, now won't start: no
    spark. Suspect crankshaft position sensor, but would be nice if I could
    verify before replacing it. The manual shown it as a simple variable
    resistor with the wiper being the sensor output and the other 2 terminals
    connected to +12 volts and ground. Looks to me like maybe a DVM on ohms
    might show something?

    That diagram is definitely misleading. It's a hall effect sensor. Check
    for battery voltage and ground in the pink and black wires of the
    connector, respectively. If that's okay, reconnect, probe the yellow
    wire, and crank the engine. Also check the three wires in the sensor end
    of the connector with your ohmmeter. There should be no continuity
    between them and ground while the connector is unplugged. You should get
    a square wave. While your DVM won't show you a square wave, I would think
    you could check with the frequency and a/c volt scales to verify that
    something is actually occurring.
