P0462 on Volkswagen
Fuel Level Sensor 'A' Circuit Low Input
P0462 on Volkswagen vehicles indicates fuel level sensor 'a' circuit low input. Au7o has documented this code across 1 Volkswagen model — most commonly on Tiguan. 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 Volkswagen range from $100 to $500, 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)
P0462 on Volkswagen by Model
Volkswagen Tiguan(1 issue)
- Fuel Level Sender Erratic Reading - Gauge Stuck, Slow to Reset After Fill-Up (P0461)2009-2023
Tiguan owners across both generations report the fuel gauge reading wrong: sticking at full for a long time after fill-up then dropping quickly, showing three-quarters with an empty tank, or failing to reset at all after refueling. On the first-generation car the cause is the in-tank fuel level sender's resistive track, which is attacked by sulfur compounds in fuel and wears at commonly used positions; the sender is part of the fuel pump/sending-unit assembly. On 2019-2023 MQB cars the same complaint sets P0461 (fuel level sensor range/performance) and Volkswagen's TSB 01-23-06 says to update the engine control software before replacing any hardware, because a calibration error rather than a bad sender is often the cause.

What does P0462 mean on Volkswagen?▼
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 Volkswagen specifically, this code is documented across 1 model.
What causes P0462 on Volkswagen vehicles?▼
Common causes on Volkswagen: 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.
