Huracan different Sensor 5v A,B,C

[TurboTim]

What are the differences in these 5 volt references? What does A,B,C mean?

[SOReilly]

The M1 has multiple independent 5V sensor supplies.

In the case of an M142 there are three 5V supplies which are available at various pins.

If a sensor failure causes an issue with one of the 5V supply circuits the others can continue to function as normal.

Also, Sensor voltage can be referenced to the corresponding 5V supply to perform a ratiometric compensation.
