P0460 — Fuel Level Sensor Circuit

minor

What it means

The control unit has detected a general fault in the fuel level sensor circuit. The sender is a float-driven potentiometer inside the tank whose resistance is read by the instrument cluster or the ECU. Typical symptoms are an erratic or frozen fuel gauge and an incorrect distance-to-empty calculation.

Likely causes (most common first)

  1. Worn or dirty resistive track on the sender potentiometer
  2. Corroded or loose connector at the fuel pump module flange
  3. Broken, chafed or shorted wiring between the tank and the cluster
  4. Jammed float arm or a float saturated with fuel
  5. Poor ground connection at the level sender
  6. Faulty instrument cluster or ECU input stage

Can you drive with it?

Driving is safe, but the fuel gauge cannot be trusted, so track mileage between fill-ups.

This is the generic meaning. What about your car?
