DTC 23: Operation Signal To Fuel Gauge

Wait for 2 seconds after selecting DTC 23. If LCD indicates 00, ensure fuel gauge moves from "F" to "1/2" to "E", resting on "F" in 2 second intervals. If fuel gauge movement is correct, fuel gauge is okay. If fuel gauge movement is not as described, replace instrument cluster. If LCD indication is 99, replace instrument cluster.
