Crank Angle Sensor Signal

Set DVOM on the 2-volt AC scale. Connect voltmeter leads to crank angle sensor, located on side of engine block. Crank engine and observe voltmeter reading. Crank angle sensor should generate a voltage signal of about .01 volt at slow cranking speed to greater than .02 volt (20 mV) at high cranking speed.
