Fuel Gauge Module: Description and Operation
Analog Instrument Cluster
Description
The fuel level indication system is a magnetic type indication system, which consists of the fuel level sensor located in the fuel tank, a fuel indicator
module located on the back of the instrument cluster, and a fuel gauge located in the instrument cluster.
Operation
The fuel indicator module provides a delay to the fuel gauge to prevent the fuel gauge pointer from fluctuating as a result of excessive movement of
fuel in the fuel tank. The fuel indicator module turns on the low fuel indicator when the fuel gauge shows approximately one-eighth tank of fuel
remaining. The fuel indicator module does not prove out the low fuel indicator; however, the indicator may flash on momentarily just after the ignition
switch is turned to the ON position.
The fuel indicator module is a small printed circuit board which latches into a pocket on the back of the instrument cluster. The electrical connections
for the ignition, ground, input from the fuel level sensor, output to the fuel gauge, and low fuel warning output (where equipped) are made through a
spring-type connector on the fuel indicator module to the flex circuit on the instrument cluster. There are no provisions for calibration or adjustment of
the fuel indicator module.
Before troubleshooting low fuel warning symptoms, first observe the fuel gauge indication. If the fuel indication is erroneous, proceed to the fuel
gauge diagnosis, then to low fuel warning diagnosis. If the fuel indication is correct, proceed directly to the low fuel warning diagnosis.
NOTE: When the fuel indicator module is replaced, the fuel gauge must also be replaced because the two parts are calibrated together.
