What causes P0460 code?

The PCM stores the code P0460 when it detects that the input signal from the fuel level sensor does not fall within the expected signal range. As the float changes positions (depending on the fuel level), the actuating rod causes a wiper-like component in the resistor to move over a resistive material.

What is a code P0460?

A P0460 refers to a discrepancy between the fuel level and what it’s being reported as being to the PCM. If the PCM receives a voltage level from the fuel level gauge that doesn’t match the actual amount of fuel in the tank, a P0460 code will be logged in the vehicle’s onboard computer.

How do I fix code p0460?

Common repairs for this code include:

  1. Repair or replacement of corroded, broken, or disconnected wiring in the electrical circuitry of the fuel sensor.
  2. Cleaning of the fuel tank ground and connections with the PCM.
  3. Testing of the voltage throughout different segments of the system between tank, sensor, and the PCM.

Does the ECM control the fuel gauge?

Fuel pumps are powered by electricity and are connected to a vehicle’s electrical system. These are connected to the ECM (Engine Control Module) or instrument cluster and relay information about the amount of fuel in the tank to the fuel gauge.
