P0462 on Volvo by model: symptoms, diagnosis and fix
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.
Common Symptoms
- Fuel gauge reads erratically, sticks, or shows empty when full
- Low fuel warning with a full tank
- Extended cranking before start, especially when hot
- Engine stumbles or stalls under load or on hills
- Whining noise from rear of vehicle
How to Fix
Confirm with a fuel pressure test at the rail and by watching live fuel-level PID data, since a bad sender is a cheap fix and a bad pump is not. The sender is available separately on most P2 cars and can be replaced through the access hatch under the rear seat without dropping the tank. If pressure is low, replace the complete pump module and the fuel filter at the same time, and inspect the pump's power feed and ground, as corroded connectors at the tank-top plug mimic pump failure. Do not simply reset the gauge; a worn sender card will re-fail.

Frequently asked questions
What does P0462 mean on a 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 it is documented across 1 model: S60.
What are the most common causes of P0462?
The most common causes of P0462 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P0462 on a Volvo?
Published repair estimates on Volvo range from $350 to $1,100 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
