What P0460 means
The fuel level sensor is a float on a resistor track in the tank unit. It is no emission part, but other monitors depend on it – the EVAP leak tests, for example, need at least 15 % fuel – so CARB requires it to be monitored and the usual exemption from the warning lamp does not apply. P0460 is the general circuit code for sensor A, the main or only fuel level sensor. Ford sets it instead of P0462/P0463 below 5 Ω or above 200 Ω for 30 s and until about 2012 also used it for a stuck sensor (fuel use compared over 100–120 miles); Saab's Trionic T8 uses it for a sensor that does not change. GM does not use P0460. The gauge then shows wrong values or a substitute, and level-dependent monitors do not run.

- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor1 to 3 hours
- Clears after repairAfter a drive cycle
Symptoms of P0460
- Fuel gauge wrong, stuck or jumping
- Range display and low-fuel warning wrong
- Check engine light (depending on the maker)
Common causes of P0460
- Most likelyResistor track worn or float arm sticking
- PossibleWire or connector at the tank unit open or shorted (corrosion)
- Less likelyInstrument cluster or gateway sends a wrong value (if the level comes via the bus)
- Less likelyFrequent topping up or overfilling (plausibility test fails without a defect)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0460 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 4 | Area: auxiliary emission controls (catalytic converter, EGR, EVAP). |
| 60 | The exact fault in that area. |
What to do next
- Note P0460 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0460
What does P0460 mean?
P0460 means "Fuel Level Sensor A Circuit". The fuel level sensor is a float on a resistor track in the tank unit. It is a generic code, so it means the same on every make.
Is it safe to drive with P0460?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P0460 fail an emissions test?
Yes, it can. P0460 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0460 to fix?
Difficulty: medium. A typical repair takes 1 to 3 hours of work. This is a job for a workshop.
Will P0460 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
