Instrument Cluster Gauge Amplifier/Check Gauge Module
WARNING: This page is about a different car, the 2002 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The fuel gauge and instrument cluster gauge amplifier must be installed as a set. The fuel gauge and instrument cluster gauge amplifier are calibrated together.
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 GAUGE indicator (if equipped) 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 installed as a unit.
