P0462 on Jeep
Fuel Level Sensor 'A' Circuit Low Input
P0462 on Jeep vehicles indicates fuel level sensor 'a' circuit low input. Au7o has documented this code across 1 Jeep model — most commonly on Wrangler. 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 Jeep range from $120 to $600, 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 Level Sender Failure — Inaccurate/Stuck Fuel Gauge (P0463)2007-2022
The fuel-level sending unit, integrated with the in-tank fuel pump module, develops a worn resistance card or a bent/sticking float arm with age. This causes the fuel gauge to read inaccurately, stick (often above or below a certain level), drop suddenly, or trigger a false low-fuel light. On JL models it can also set P0463 (fuel-level sensor circuit high) and on inclines the gauge may briefly read empty until the vehicle is back on level ground. A persistent fault sometimes traces to chassis-harness wiring rather than the sender itself.

What does P0462 mean on Jeep?▼
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. 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. On Jeep specifically, this code is documented across 1 model.
What causes P0462 on Jeep vehicles?▼
