Any idea as to what is P0463 error? What roles does Powertrain Control Module play? Are you interested in knowing more about this issue? Keep reading ahead. The amount of fuel in the fuel tank is conveyed to the Powertrain Control Module (PCM) by the Fuel level Sensor.

The fuel level sensor conveys the information by using a float on a level that is linked to an electronic device called potentiometer. A potentiometer has the ability to interpret the movement or position of a lever into a voltage signal which the computer can understand. For instance, the operation of gas by a driver when it open or closes the throttle or a potentiometer is used by a throttle pedal. The code P0463 shows that the fuel level sensors have voltage signals that are very high and it indicates that the condition is impossible as the fuel tank is holding fuel more than it could actually hold.

The low-voltage signal defines the amount of fuel present in the tank by the PCM. Naturally, five volts will be the highest voltage reading, and a reading you obtain below the normal range set by the manufacturer will show a P0463 code.

What causes this problem with the Fuel Level Sensor Circuit High Input?

• Issues with the fuel level sensor circuit
• Damaged/ broken fuel level sensor
• A fault in the fuel level sensor float that is present inside the gas tank
• Gas tank that is either damaged or corroded
• Faults with the PCM (Occasionally)

1. Fuel Level Sensor - If there is any leaky area in your fuel level sensor, then it’s high time that you replace them as soon as possible.
2. Fuel Tank - Repairing or replacing your damaged fuel tank can be one of the best way to get rid of the P0463 error code.
3. Fuel Pump - Is your fuel pump damaged? Looking for the right place to replace your fuel pump? Parts Avatar has got the replacement parts for every make. Get them online at the best prices.
4. Fuel Level Gauge - A fault in the fuel level gauge can arise if there are any leaks or blockages. Check for leaky areas and fix them instantly.
5. Fuel level sensor harness - Any cut or shorted wire in this component can make your engine system fail. Get rid of it by replacing them soon.
6. Powertrain Control module - Replacing your faulty powertrain control module can help you to avoid OBD- II error.

If you are facing OBD error code P0463, then there are significant common symptoms that can be felt or observed. We have worked out a list here to help you out in understanding this problem better.

Common Symptoms

• Check light engine that is illuminated
• Fluctuating or inaccurate signal in the fuel gauge
• Fuel light that is well lit and / or warning of alarm for low fuel

After understanding the symptoms and few common causes behind the OBD error code, we are here to help you out in understanding the ways and means to correct the issue. To solve any issue, you need to follow certain steps, and to solve OBD error code P0463, you will need to undergo the following replacements:

• Repair or replacement of the fuel tank
• Restoring or changing the fuel level sensor float
• Changing or restoring the fuel level sensor
• Changing the wire joints for the fuel level sensor
• Tighten if any weak connections in the fuel level sensor circuit

However, if you face any issue then we have stocked a wide range of best priced Fuel Level Sensor, fuel tank, fuel pump, fuel level gauge, Fuel Level Sensor harness, Powertrain Control Module and more to help you out in fixing your car.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0463 code to be stored:

• The mechanic will use OBD – II scanner to check the codes and other related codes when he diagnoses a P0634 error. Once the check is done, the codes will be cleared and the mechanic will try to duplicate the situation in which the code was primarily recorded. The mechanic will have a close look on the data it provides as well as the fuel gauge, so that he can determine if it is steady or irregular, whether the amount of fuel present in the tank is more or less than it actually should be, etc.
• After the test drive is taken, the mechanic will gradually work through all the possible causes by clearing the codes and will retest it with each pair until and unless the problem of the code is solved.

Common Mistakes When Diagnosing the P0463 Code

• Replacing the fuel pump when the problem is actually a damaged or faulty fuel gauge or fuel level sensor.
• Before you inspect the wire and connectors for any faults or shorts, try replacing the larger and expensive components.
• Replace the fuel gauge if there is any corrosion or if there are any damaged wires or connections.
