P0462 on Hyundai
Fuel Level Sensor 'A' Circuit Low Input
P0462 on Hyundai vehicles indicates fuel level sensor 'a' circuit low input. Au7o has documented this code across 1 Hyundai model — most commonly on Elantra. P0462 indicates the powertrain control module detected a fuel-level sensor signal voltage that is lower than the normal operating range — often interpreted as an empty or near-empty reading that may not reflect the actual fuel amount. The fuel level sender reports tank level via a variable resistance, and an abnormally low signal can stem from a short to ground or a failed sender. This usually shows up as a stuck-low or inaccurate fuel gauge rather than a driving problem. It is low-urgency but should be corrected so the gauge and EVAP monitors work properly. Typical repair costs on Hyundai range from $350 to $900, depending on the specific model and root cause.
Common Causes of P0462
- •Faulty fuel level sensor / sending unit
- •Short to ground in the signal wire
- •Corroded or damaged connector at the fuel pump module
- •Open or high-resistance ground circuit
- •Worn sender resistor card or float
- •Damaged wiring harness to the tank
- •Instrument cluster or PCM fault (less common)

- Fuel Pump Module and Fuel Level Sender Failure Causing No-Start or Inaccurate Gauge Readings2001-2006
Owners of 2001-2006 Elantras frequently report in-tank fuel pump module problems, including hard starting, no-start conditions, and erratic fuel gauge behavior due to sender wear. On higher-mileage cars, the pump can become weak or fail intermittently, especially after hot soak. Forum reports and repair histories commonly pair pump replacement with sender issues because both are integrated in the tank module.

What does P0462 mean on Hyundai?▼
P0462 stands for "Fuel Level Sensor 'A' Circuit Low Input." P0462 indicates the powertrain control module detected a fuel-level sensor signal voltage that is lower than the normal operating range — often interpreted as an empty or near-empty reading that may not reflect the actual fuel amount.

This usually shows up as a stuck-low or inaccurate fuel gauge rather than a driving problem. It is low-urgency but should be corrected so the gauge and EVAP monitors work properly. On Hyundai specifically, this code is documented across 1 model.
