PO463 code what is the fix?

Question

What does these code mean Po 463 and Po446..I replaced the sedning unit and still the same

Answer 1

HI there,

As you know the P0463 is a code for the fuel level sensor. If you've already replaced it and it hasn't resolved the issue, then you either have a wiring problem or a problem with the gas gauge.

P0446 is a code for a purge control on the evap system. This code could appear if you didn't get the seal tight on the sending unit or if there is some kind of leak in the evap system, or the purge control solenoid itself could be bad. Usually a smoke test is required to resolve this issue.
