P0463 on a Volvo: Causes, Fixes & Repair Cost

🟢 Low severity · drivable

Safe to drive, but the fuel gauge may be wrong — track your miles or fill up often so you don't run out of gas.

What P0463 means on a Volvo

On a Volvo, P0463 means the fuel level sender is sending a signal that's too high, so the computer reads the tank as full. The sender is part of the fuel pump module on most Volvos, and its resistor strip wears with age. The engine runs normally; the fuel gauge is what's affected.

Is P0463 common on Volvos?

P0463 shows up on higher-mileage Volvos like the S60, XC60, and XC90. Sender wear is the usual cause, and the module sits inside the tank, so replacement is labor-intensive. It's a gauge problem, not a drivability problem.

Commonly reported on: S60, XC60, XC90.

Symptoms

Check engine light on
