Mountaineer 2WD V6-245 4.0L VIN X SFI (2000)
Fuel Gauge Module: Description and Operation
NOTE:
-
The fuel gauge and instrument cluster gauge amplifier must be replaced as a set. The fuel gauge and instrument cluster gauge amplifier are
calibrated together.
-
If the ignition key is left in the ON position during fueling, a slow to respond fuel gauge indication may result. The ignition key must be placed in
the OFF position during or after refueling for accurate fuel gauge indication.
The instrument cluster gauge amplifier electrically averages the fuel sender readings so the gauge displays the actual fuel level and not the fluctuations
due to fuel sloshing. The amplifier also supplies the signal to illuminate the CHECK GAGE indicator to indicate low fuel, high engine coolant
temperature, or low engine oil pressure. The gauge amplifier is a small printed circuit board located in a pocket on the back of the instrument cluster. The
electrical connections are made with a spring-type connector. There are no provisions for calibration or adjustment. The fuel gauge and the instrument
cluster gauge amplifier must be replaced as a unit.
