| style="text-align: left; vertical-align: top;" | A fuel tank level sensor exists in most cars, which shows the approximate fuel level in the driver’s indicator panel. It is possible to connect {{{model|FMB1YX}}} Analog input to it (if sensor returns analogue signal proportional to fuel level). After the connection to the tank fuel level sensor, calibration is needed. Calibration is needed because most fuel tank sensors are not linear. Calibration is performed by measuring voltage dependence on volume of fuel in tank.
