Sub-Crankshaft Position Sensor Signal (Q45)

Set analog voltmeter to 100-mV AC scale. Connect positive voltmeter lead to terminal "a" and negative voltmeter lead to terminal "b" of sub-crankshaft position sensor terminal connector. See Figure . Rotate crankshaft position sensor shaft slowly by hand; voltmeter should deflect. If analog voltmeter does not deflect, replace crankshaft position sensor.
