CEL- Need definition.

[aveo owner]

Hello all, I have a 2004 Chevy Aveo (Kalos) and I received a PO463 when I checked the CEL. It says that it's a fuel level sensor A circuit high input. In your opinion does this mean that the fuel sending unit is on the way out? The CEL keeps coming off and on, it doesn't stay on all of the time and it hasn't affected the running of the car as far as the wife can see. Is this serious or do I just ignore it until it rears its ugly head for good?

Thanks for your help.

i'd say it is nothing major but at least check the wiring of the sending unit... being intermittent suggests that their is something constantly getting connected/disconnected or so
