The fuel gauge will drop to the peg and ring the bell and light the
light then recover after a while.
Only happens when the tank is 1/4 full or less. Once, after a fill up
the gauge stayed on the peg for several minutes then recovered.
Happens when sitting still or in motion on the level or a grade.
Experts in two dealer service department haven't got a clue.
Any a yinz guys got a good guess?
Just a WAG, but the gauge is actually driven by the PCM (or one of the
other computers) IIRC. It is possible that there is a bad connection at
the computer that is causing this.
I know my Dodge truck's fuel gauge is strange if I don't buy a full tank
of fuel--it can take as much as five minutes to read the correct fuel
I'm gonna have to try this as soon as I get home.
The instrument cluster self-diagnostic test will put the instrument
cluster into its self-diagnostic mode. In this mode the instrument
cluster can perform a diagnostic test that will confirm that the
instrument cluster circuitry, the gauges, and the indicators are capable
of operating as designed. During the test the instrument cluster
circuitry will position each of the gauge needles at various calibration
points, illuminate all of the segments in the Vacuum Fluorescent Display
(VFD) unit, and turn all of the indicators ON and OFF again.
Successful completion of the self-diagnostic test will confirm that the
instrument cluster is operational.
Begin the test with the ignition switch in the OFF position.
Depress the odometer/trip odometer switch button.
While still holding the odometer/trip odometer switch button depressed,
turn the ignition switch to the ON position, but do not start the
Release the odometer/trip odometer switch button.
The instrument cluster will simultaneously begin to illuminate all of
the operational segments in the VFD unit, and perform a bulb check of
each operational LED indicator. The VFD segments and LED indicators
remain illuminated as each gauge needle is swept to several calibration
points and back. If a VFD segment or an LED indicator fails to
illuminate, or if a gauge needle fails to sweep through the calibration
points and back during this test, the instrument cluster must be
