Fuel Gauge
WARNING: This page is about a different car, the 2003 Kia Spectra. However, it is still accessible from the selected car via links, so may be relevant.
Electrical fuel gauge system consists of an electrical panel gauge and a fuel tank sender device. Fuel gauge indicates quantity of fuel in fuel tank only when ignition is turned to "ON" position. When ignition switch is turned to "ACC" or "LOCK" positions, pointer does not point to correct fuel level.
