Crank Angle & Sub-Crank Angle Sensor Signal

Remove crank angle sensor from engine. Do not disconnect crank angle sensor harness connector. Turn ignition switch on, engine off.
Connect negative voltmeter lead to ground. Rotate crank angle sensor shaft slowly by hand. Connect positive voltmeter lead to crank angle sensor connector terminal No. 1 (90-degree signal), voltage should fluctuate between 0-5 volts. Move voltmeter positive lead to terminal No. 2 (one-degree signal), voltage should also fluctuate between 0-5 volts. See Fig 1 .

Set voltmeter to 100 mV AC scale. Connect positive voltmeter lead to terminal "a" and negative voltmeter lead to terminal "b" of sub-crank angle sensor terminal connector. See Fig 1 . Rotate crank angle sensor shaft slowly by hand, voltmeter should deflect. If voltmeter does not deflect, replace crank angle sensor.
