At the sensor, probe the gray/black wire with a fine straight pin. Then do the same for the black/light blue wire. When the engine has cut out, use a digital voltmeter to test the voltage between the two pins. Have on board a ratchet and socket that fits the crank shaft pulley bolt so you can turn the engine by hand. With the ignition switch in the "run" position, as you turn the crankshaft the voltage should oscillate between 5.0 and 0.3 volts, 3 times for every revolution of the crank. If that isn't seen to be happening then the sensor is bad.
