CRANK SENSOR

Unplug sensor connector,using a digital volt ohm meter set on ac volts position.Connect the leads to the two pins in the connector of the crank sensor.Then have a helper crank engine over.You should see ac voltage,if not,then your crank sensor is bad.

CAM SENSOR

Pin 1 is +5V, pin 2 is Ground and pin 3 is the signal. Use analog voltimeter in pin 2 and 3. Crank the engine: the pointer of the voltimeter shoud oscilate in range 0V to 5V.
