Check Engine Light and Erratic Fuel Gauge Operation on Isuzu Amigo

The fuel level sensor may fail resulting in erratic fuel gauge operation and illumination of the Check Engine Light. Replacement of the fuel sender assembly is recommended to correct this concern. A powertrain control module (PCM) software update may be necessary for the updated fuel level sensor to read correctly.
