P0462 on Volvo
Fuel Level Sensor 'A' Circuit Low Input
P0462 on Volvo vehicles indicates fuel level sensor 'a' circuit low input. Au7o has documented this code across 1 Volvo model — most commonly on S60. 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 Volvo range from $350 to $1,100, 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)

- In-Tank Fuel Pump Module and Fuel Level Sender Failure2001-2007
Fuel system complaints are the single largest NHTSA category on the early P2 S60 (roughly 74 complaints on the 2002 and 92 on the 2001). Two distinct parts fail. The fuel level sender's resistive card wears where the wiper arm sweeps, so the gauge reads erratically, sticks full, or drops to empty with a full tank and triggers the low-fuel warning. Separately, the in-tank fuel pump module loses pressure with age and heat, producing long cranking, hot-restart no-starts, stumbling under load, and eventual stalling. Because the pump and sender share one tank-top module, a failure of either usually means dropping or accessing the same assembly.

What does P0462 mean on Volvo?▼
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 Volvo specifically, this code is documented across 1 model.
