P0460 - OBD Trouble Code

<<See All OBD Codes

The engine control module (PCM) gets information from the Fuel level Sensor as to how much fuel is present inside the fuel tank. If the PCM detects an incorrect signal from the fuel level sensor, then the P0460 code will be set. The Fuel level Sensor may or may not be a part of the fuel pump.

The amount of fuel present in a vehicle's tank is informed to the PCM in terms of voltage. A P0460 error code refers to the difference between the fuel level and what it's being stated to the PCM. A P0460 issue can be due to a malfunctioning fuel level sensor. A P0460 code will be recorded in the vehicle's onboard computer if the voltage level received by the PCM from the fuel level gauge doesn't coincide the original amount of fuel in the tank. A P0460 error code can also be recorded if the input voltage level surpasses the extreme factory level.

The fuel level sensor is placed in the unit of fuel level sensor. The sensor identifies a fuel level in the fuel tank and conveys a signal to the Engine Control Module (ECM). The fuel level sensor comprises of two parts which is mechanical float and a variable resistor. The output voltage of the fuel level sensor changes with subject to the movement of the fuel mechanical float.

What causes this problem with the Fuel Level Sensor Circuit Malfunction?

• A Fault in the Fuel Level Sensor
• A connection to the Fuel Level Sensor is open or shorted
• A poor electrical connection to the Fuel Level Sensor circuit
• A fault in the combination meter

1. Fuel Level Sensor - Get your fuel level sensor instantly replaced if you witness any faults.
2. Fuel Tank - Check for any visible damages in your fuel tank. If you find so, repair and replace them soon.
3. Fuel Pump - A fault in the fuel pump can trigger the P0460 code. Check for faults and repair them as desired.
4. Fuel level gauge - If the fault level gauge does not operate properly, it can give rise to this error code. It’s better to get them fixed.
5. Fuel Level Sensor harness - A shorted or open Fuel Level Sensor harness has to be replaced or repaired to avoid P0460 error.
6. Powertrain Control Module - Parts Avatar has the right replacement parts for every engine make. Get the replacement part of Powertrain Control Module at the best price online.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P0460 here:

Common Symptoms

A P0460 will interrupt the dashboard fuel gauges ability to precisely report the level of your tank's fuel. The readings of the fuel gauge may be unpredictable or read elsewhere off the charts. Vehicles that are well fit with a low fuel blinker feature will also suffer from erratic low fuel cautions as a result of P0460. If the P0460 code is not reported alongside with other trouble codes, then all the vehicle's necessary systems will function normally.

Here are some ways with the help of which you will be able to correct the OBD Code P0460:

If you detect any faults, corroded, broken or separated wires in the electrical circuit related to the fuel sensor, it has to be fixed or replaced as needed. Clean the fuel tank ground and connections with the PCM carefully so as to promote a better current. Test the voltage all through the different segments of the system like the tank, sensor, and PCM. If there's a voltage difference of more than 1 volt between segments, then rectify the fault in the area. Replace and re-join faulty components as desired. Now start the vehicle and check all the system related to fuel in order to ensure that the repairs are done.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0460 code to be stored:

The mechanic will use an OBD-II code reader to identify a P0460 code. Next, he will check for the electrical circuits if there are any signs of corrosion, interruption or loss. If the electrical circuits are noisy, then check for faults or damage in the sensor components. If the fuel sensor is perfectly fine, then check the fuel tank and PCM for any damages. If there are any other trouble codes logged in your vehicle's computer you may use them as a guide to search for your problem.

Common Mistakes When Diagnosing The P0460 Code

• Failure of the Fuel pump
• Fault in the Powertrain Control Module (PCM)
• Problem with wires
