The P0463 code on a 1998 Cadillac indicates a problem with the fuel level sensor circuit. This code suggests that the vehicle's engine control module (ECM) is detecting an out-of-range voltage signal from the fuel level sensor, which can lead to inaccurate fuel gauge readings. Potential causes include a faulty fuel level sensor, damaged wiring, or a poor electrical connection. It's advisable to inspect these components to diagnose and resolve the issue.
