P0460

Fuel Level Sensor A Circuit

Fuel level sensor Generic OBD-II Low

What it means

P0460 means the ECM has detected a fault in the fuel level sensor circuit — the tank-mounted sender that drives your fuel gauge. The engine runs normally, but the gauge reading can be wrong or erratic, so the practical risk is running out of fuel unexpectedly. The usual cause is a failed sending unit or its wiring.

Can I keep driving? The engine runs fine, but the fuel gauge may be wrong — the real risk is running out of fuel unexpectedly, so keep an eye on your mileage until it's fixed.

How to diagnose & fix

Work through it in order

Read the live fuel-level signal and compare it with the actual tank level to confirm it's out of range or erratic.
Inspect the wiring and connector to the fuel level sending unit for corrosion, opens, or shorts.
Access the sending unit and test its resistance across the float's travel; replace it if it's open or erratic.
Repair any wiring faults, then clear the code and verify the gauge tracks correctly.
Only suspect the instrument cluster or PCM after the sender and wiring are confirmed good.
