Open the rocker cover has two kinds of motorcycle fuel tank inside the sensor, the other kind of magnets + induction hall, a variable resistance slide type, it is ok to change. There are 47 k seal variable resistance, remove the sensor, for testing.

Capacitive sensing part of the oil level sensor is a coaxial container, after the oil into a container sensor shell and sensor caused by the change of capacitance between electrodes, the change amount by the transformation of the circuit and precise linear and temperature compensation, supply standard 4-20 ma output signal display instrument.
