Notes:
The reason why the value in display field 1 rises
and the value in display field 2 falls is because
the potentiometers (angle senders) in the
throttle valve control module work in opposite
directions.
The percentage value for the first potentiometer
increases as the voltage rises towards 5 V
because the voltage at this potentiometer
increases as the throttle valve opens.
The percentage value for the second
potentiometer decreases as the voltage drops
away from 5 V and towards 0 V because the
voltage at this potentiometer decreases as the
throttle valve opens.
