When your Hyundai vehicle is having issues with code P0463, it’s important to understand the cause and solution of this problem. This code indicates a Fuel Level Sensor “A” Circuit high Input issue with the engine. The output voltage is monitored and if it is less than 0.02 volt, or output voltage is less than 0.039 volt for 300 seconds, when the engine speed is not 0 miles, you may have a problem with the sensor output voltage. To better understand the causes and solutions of this problem, let’s take a look at the table below.
Hyundai Code P0463: Causes and Solutions
| Cause | Solution |
|---|---|
| Short to battery in fuel level (FLS) circuit | Check for short to battery in the fuel level sensor circuit, replace or repair as necessary. |
| Faulty fuel level sensor | Replace the fuel level sensor. |
| Faulty ECM/PCM | Replace the ECM/PCM. |
| Incorrect or damaged wiring | Replace any incorrect or damaged wiring. |
When your Hyundai vehicle has code P0463, it’s important to understand the cause and solution to the problem. This code indicates a Fuel Level Sensor “A” Circuit high Input issue with the engine. The output voltage is monitored and if it is less than 0.02 volt, or output voltage is less than 0.039 volt for 300 seconds, when the engine speed is not 0 miles, you may have a problem with the sensor output voltage. This can be caused by a number of factors, such as a short to battery in the fuel level sensor circuit, a faulty fuel level sensor, a faulty ECM/PCM, or incorrect or damaged wiring. To solve this issue, it’s important to check for a short to battery in the fuel level sensor circuit and replace or repair as necessary, replace the fuel level sensor, replace the ECM/PCM, and replace any incorrect or damaged wiring. To get a better understanding of the possible causes and solutions of Hyundai code P0463, take a look at the table below.
