    This step determines if there is a 5-volt reference.

  3. 7

    This step verifies whether the sensor is sending a signal back to the PCM.

  4. 11

    The PCM supplies 5 volts on the signal circuit. This step determines if that voltage is present, not present, or if too much voltage is present.
