What does code P0462 mean?

P0462 means the level signal is stuck low: gauge pinned on empty regardless of actual fuel. Severity is low: plan the repair, but it isn’t an emergency.

What does P0462 mean in plain words?

The level signal is stuck low: gauge pinned on empty regardless of actual fuel. A short to ground or a sender at the end of its resistive track; verify at the tank connector before dropping the tank.

Can I drive with a broken fuel gauge?

Mechanically yes, track miles with the trip odometer and refill early. The hidden costs: EVAP monitors may not run (inspection readiness) and running genuinely low overheats the in-tank pump that the fuel normally cools.

Why does my gauge work but the code persists?

The computer watches the signal's plausibility over time, not just the needle. A dead spot the needle skips past quickly still logs. Live data shows what the gauge hides.

P0462: Fuel Level Sensor Circuit Low

Low

Quick answer

P0462 means the level signal is stuck low: gauge pinned on empty regardless of actual fuel. First move: a short to ground or a sender at the end of its resistive track; verify at the tank connector before dropping the tank.

What it means

P0462 reports that the level signal is stuck low: gauge pinned on empty regardless of actual fuel.

The fuel level sender is a float on an arm sweeping a resistive track inside the tank, usually built into the fuel pump module. It affects nothing about how the engine runs, but it does affect the EVAP system's leak tests (which need a known fuel level) and, more practically, whether you can trust your gauge.

The steps below run cheapest-first, because in this family, the cheap causes really are the common ones.

P0462 symptoms: what you'll notice

The fuel gauge sits pinned on empty no matter how much gas is actually in the tank.
The low-fuel light stays on constantly, even right after filling up.
Check engine light on; the engine itself runs completely normal.
The distance-to-empty readout shows zero or near zero all the time.

How to fix it: diagnosis, step by step

Cheapest and most likely checks first.

1 Characterize the gauge

Stuck full, stuck empty, frozen mid-tank, or jumpy over bumps: each points differently (open circuit, short, dead spot on the track, loose float arm).
2 Test at the tank connector

Most senders are a simple variable resistance: measure at the tank-module connector and compare against the spec range from empty to full. Wiring to the gauge gets tested the same way.
3 Plan the repair realistically

The sender usually comes as part of the fuel pump module. If the pump is original and high-mileage, replacing the whole module while the tank is down is the once-not-twice decision.
