P0462 Code: Fuel Level Sensor A Circuit Low
🟢 Low severity · drivable
Safe to drive — the fuel gauge may read incorrectly, so keep track of fuel with the trip meter.
What P0462 means
The fuel level sensor (fuel sender) in the tank is sending a signal that reads too low — often empty even when the tank has fuel. A short to ground, a bad sender, or a wiring fault can cause this.
Symptoms
- Check engine light is on
- Fuel gauge reads empty or wrong
- Low fuel warning light stays on
- Usually no drivability problems
Common causes
- most common: Faulty fuel level sender
- common: Short to ground in the wiring
- common: Corroded or loose connector
How to fix it
| Fix | DIY? | Typical cost |
|---|---|---|
| Check and repair the wiring to the sender | Yes | $20–100 |
| Replace the fuel level sender | Mechanic | $100–300 |
| Have a shop verify the gauge and cluster if needed | Mechanic | $100–200 |
