Can drive — fix at your convenience.
P0463 means the computer is seeing a higher-than-normal signal from the fuel level sensor inside your tank. This is usually an electrical issue rather than an engine problem. The main effect is an inaccurate fuel gauge.
$80 – $500
Varies by vehicle and root cause.
Yes, it's usually safe to drive. The catch is that your fuel gauge may be unreliable, so track your mileage and refuel before you risk running empty.
A simple wiring or connector repair can be as low as $80-$150. Replacing the fuel level sensor or the whole sending unit usually runs $200-$500 because the tank often has to be accessed.
It's a low-severity code for your engine, but it's annoying and can leave you stranded if you run out of fuel by trusting a bad gauge. It's worth fixing for peace of mind.
The sensor that measures fuel in your tank is sending a faulty high signal, so the gauge can't show the real level. Until it's repaired, rely on your trip odometer to estimate when to fill up.
