Speed sensor voltage checks. All checks should be made with the sensor connected to the gauge and the key
on. Checks should be done with a volt meter and not a test light.
3-wire sensor: Red wire should have 9-11 volts dc, slightly less than battery voltage.
Black wire should show ground, 0 volts dc at all times.
White wire should vary between 0 and 5 volts dc as the gear teeth pass by the sensor.
2-wire sensor: Measure the voltage between the two sensor wires. With the wheel spinning the voltage should be
about 1-10 volts ac (make sure the meter is set to AC volts and not DC volts for this check).
