What is the P0463 fault number? What causes the P0463 fault code How do you fix the P0463 fault code What does the Fuel Level Sensor Circuit High Iput Malfunction (or ?….) mean?
What is the P0463 fault code?
The Powertrain Control Module (ECM/PCM/ECU), monitors the fuel level sensor signals. This information can be used to adjust fuel level needles on the instrument panel based on fuel tank contents and to notify the driver.
If the ECM receives high input signals from the fuel level sensor, it will set Trouble Code P0463 and light up the check engine light to notify drivers. If the fuel level sensor detects a fuel level higher than the actual fuel level, a code P0463 will be issued.
Because the fuel gauge does not always show the correct level of fuel, code P0463 can lead to confusion. It is possible to run out of gas if you don’t know how much fuel you have in your tank.
Note: Code P0463 is a general code that has been defined by the American Society of Automotive Engineers, (SAE). However, the definition of the code can vary depending on the manufacturer of the vehicle.
What is the P0463 Fault code?
The most common reasons that the ECM will store code P0463 are:
- – A malfunction in the fuel level sensor circuit
- – Defective fuel level sensor
- – Defective fuel float
- – A damaged or dirty fuel tank
- – A defective smart fuse box/integrated power module (if applicable).
- ECM Failures are rare
What are the symptoms for P0463 Fault Codes?
- – Illumination and operation of the engine fault lamps
- Fluctuating or faulty fuel gauge
- – Continuously burning or flashing fuel light
- – Fuel shortage signal
How do I fix the P0463 fault code?
Before you proceed to the P0463 fault repair, it is important that other fault codes are checked with the scanner. If necessary, repair steps should also be taken.
It is a common error to simply replace the fuel pump without checking it. The fuel level sensor, and the fuel gauge, should be checked. Any tests that are necessary should also be performed. To determine if the system is experiencing a short circuit, it is important to inspect cables and connectors.
- – Reparation or replacement fuel tank
- – Repair of or replacement of fuel float
- – Reparation or replacement of fuel level sensor
- – Replacing fuel level sensor wiring harness
- – Connecting the fuel level sensor circuit to a tighter bolt
What is the importance of the P0463 Fault Code
The code does not create dangerous situations for the vehicle. It is possible for your vehicle to run out of fuel and you could be forced off the road. It is in your best interest to have the vehicle repaired as soon as possible.
