How to diagnose and fix P0460: most-reported vehicles
Ranked by owner reports. Each card gives the symptoms, how to confirm the cause, the fix, parts and sources for that vehicle.
GMC Sierra 3500HD · 2007–2014
On 2007–2014 Sierra 3500HD models, the fuel tank mounting straps and the fuel level sender unit are prone to corrosion, causing inaccurate fuel gauge readings and in some cases complete sender failure. NHTSA complaint data documents numerous owners reporting sudden fuel gauge drops to empty or erratic readings unrelated to actual fuel level. The plastic float arm on the sender can also crack, exacerbating the problem.
Common Symptoms
- Erratic or inaccurate fuel gauge readings
- Fuel gauge stuck on full or empty regardless of tank level
- Low fuel warning activating with significant fuel remaining
- Running out of fuel despite gauge showing fuel remaining
- DIC fuel range displaying incorrect distance to empty
How to Fix
Replace fuel level sender/pump module assembly (ACDelco M100087 or equivalent). Inspect and replace corroded fuel tank straps if necessary (GM part 15811919). Tank may require drop for full access. Application of anti-corrosion spray on new straps is recommended. Labor 2–3 hours; flush tank if sediment contamination is present.

Volvo V50 · 2005–2011
The Volvo V50 fuel pump module located inside the fuel tank can fail, causing starting issues and stalling. The fuel level sender can also fail separately, causing inaccurate fuel gauge readings.
Common Symptoms
- Long cranking before start
- Stalling at low fuel levels
- Inaccurate fuel gauge
- Loss of power under load
- Whining from fuel tank area

Peugeot 206 · 1998–2012
The in-tank fuel level sender on the 206 commonly fails or misreads: the float arm sticks at certain levels, the resistive track wears, or the connector terminals on top of the pump/sender module corrode and lose contact. Owners see the gauge stuck on full or empty, wild fluctuation between readings, or a permanently lit low-fuel light, making it easy to run out of fuel unexpectedly. The fault is well documented across 206 owner forums with established access and repair procedures.
Common Symptoms
- Fuel gauge stuck on full or empty
- Gauge fluctuates wildly between readings
- Low fuel warning light on with a full tank
- Gauge reading changes after hitting bumps
- Running out of fuel despite gauge showing remaining range
How to Fix
Access the sender through the hatch under the rear seat cushion, clean and re-tension the connector terminals and inspect the wiring; if the float or resistive track is worn, replace the sender (or combined pump/sender) unit. No tank removal is required.

Frequently asked questions
What does P0460 mean?
P0460 stands for "Fuel Level Sensor Circuit Malfunction." This code means the powertrain computer sees a problem in the fuel level sensor circuit, the sender unit inside your fuel tank that tells the gauge and computer how much fuel is present. The reading may be erratic, stuck, or not changing as fuel is used, which the computer flags as a malfunction. While it mainly causes an inaccurate or erratic fuel gauge, the computer also uses fuel level for some emissions (EVAP) tests, so it can affect monitor readiness. It generally points to the sending unit or its wiring rather than the engine itself.
What are the most common causes of P0460?
The most common causes of P0460 are: Faulty fuel level sending unit (float/sensor) in the tank, Corroded or worn sensor resistor card, Damaged or shorted wiring to the fuel level sensor, Loose or corroded connector at the tank or harness, Stuck or broken float arm, Poor ground in the fuel sender circuit, Faulty instrument cluster or PCM (less common). The specific cause varies by vehicle.
How much does it cost to fix P0460?
Repair costs for P0460 range from $30 to $900, depending on the vehicle and root cause.
Which vehicles are affected by P0460?
Au7o has documented P0460 across 4 vehicle models from 4 manufacturers: Ford, GMC, Peugeot, Volvo.
