Circuit Operation
Fuel Gauge
The fuel gauge consists of two intersecting coils
wound around a permanent magnet rotor. When
voltage from fuse C-10 is applied to the coils, a mag-
netic field is generated. This causes the rotor to rotate
and the gauge needle to move. The magnetic field is
controlled by the engine or powertrain control module
(ECM or PCM), which receives input from the fuel tank
unit, at E-22 pin 60.
Low Fuel Warning Light
When there is not an adequate amount of the fuel in the
fuel tank, the ECM or PCM will provide ground at E-21
pin 31 and the light will illuminate. The ECM or PCM
determines when the fuel is low based on input re-
ceived from the fuel tank unit, at E-22 pin 60.
