P0460: Fuel Level Sensor Circuit Malfunction
Can you still drive? Yes, but you cannot rely on the fuel gauge. Use your trip odometer to track mileage and refuel based on miles driven to avoid running out of fuel.
What Does P0460 Mean?
Code P0460 indicates a general malfunction in the fuel level sensor circuit. The fuel level sensor, located inside the fuel tank as part of the fuel pump assembly, uses a float and variable resistor to report the fuel level to the instrument cluster and ECM. A circuit malfunction means the readings are erratic, missing, or irrational.
Need to read your codes?
An OBD-II scanner lets you read and clear diagnostic trouble codes from your vehicle's computer. Most scanners work with any car made after 1996.

- Faulty fuel level sensor (sending unit)
- Corroded wiring or connector at the fuel tank
- Failed fuel pump module containing the sensor
- Damaged float arm on the fuel level sender
- Open or shorted wiring in the fuel level circuit
Symptoms
- Inaccurate fuel gauge reading
- Fuel gauge stuck on empty or full
- Check engine light on
- Low fuel warning light may illuminate incorrectly
Diagnostic Steps
- 1Monitor fuel level sensor signal with a scan tool and compare to actual fuel level
- 2Check wiring and connector at the fuel tank for corrosion or damage
- 3Measure fuel level sensor resistance at the tank connector with the sensor disconnected
- 4Move the float arm manually and verify resistance changes smoothly
- 5Inspect the float for fuel saturation or damage
- 6Replace the fuel level sending unit if tests confirm failure

1 Active Recall — 2026 Ford F-150
The following NHTSA safety recalls have been issued for this vehicle. Contact your dealer to check if your vehicle is affected.
ELECTRICAL SYSTEM: INTEGRATED TRAILER BRAKE CONTROL
Ford Motor Company (Ford) is recalling certain 2021-2026 F-150, 2022-2026 F-250 SD, F-350 SD, F-450 SD, F-550 SD, Maverick, 2024-2026 Ranger, 2023-2026 F-600 SD, 2022-2027 Lincoln Navigator, Expedition, and 2026 E-Transit vehicles. When towing a trailer, the integrated trailer module (ITRM) may lose communication with the vehicle, possibly causing a loss of brake and turn signal lights, or a loss of brake function. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, " Lamps, Reflective Devices, and Associated Equipment."
Remedy: The integrated trailer module software will be updated by a dealer, or through an over-the-air (OTA) update, free of charge. Owner notification letters are expected to be mailed March 17, 2026. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 26C10. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on NHTSA.gov beginning March 17, 2026.

Frequently Asked Questions
Why does my fuel gauge read wrong?
The fuel level sensor inside the tank uses a float and variable resistor. When the resistor wears out, the float sticks, or the wiring fails, the gauge receives incorrect information and displays the wrong fuel level.
Do I need to replace the whole fuel pump to fix the gauge?
Not always. On some vehicles the fuel level sending unit can be replaced separately from the fuel pump. On others, it is integrated into the fuel pump module and must be replaced as an assembly.
