All analog sensors.
This fault condition is seldom caused by the
simultaneous failure of all sensors. It is more usually the
result of the failure of the analog drive voltage, which is
the supply voltage for all sensors. This power supply fault
may be due to the failure of the power supply or may be
due to damage to the cable that connects the sensor to
the computer.
When this fault occurs, carry out Power Supply Voltage
checks before checking individual sensors.
