A P0463 code on a Dodge Ram indicates a problem with the fuel level sensor circuit. This code is triggered when the powertrain control module (PCM) detects an incorrect signal from the fuel level sensor, which is responsible for measuring the amount of fuel in the vehicle’s fuel tank.
P0463 code on a Dodge Ram
Possible causes for a P0463 code include:
- Faulty fuel level sensor
- Damaged or corroded wiring or connectors
- Malfunctioning fuel gauge
- Problems with the fuel pump module or its wiring
- Faulty PCM (rare)
To diagnose and fix this issue, follow these steps:
- Perform a visual inspection: Check the wiring and connectors related to the fuel level sensor for any visible signs of damage or corrosion.
- Test the fuel level sensor: Using a digital multimeter, test the fuel level sensor’s resistance and compare it to the manufacturer’s specifications. If the sensor is faulty, replace it.
- Check the fuel gauge: Turn on the ignition and observe the fuel gauge on the instrument cluster. If it’s not working properly, it may need to be replaced.
- Inspect the fuel pump module: Check the fuel pump module and its wiring for any signs of damage or wear. Repair or replace as necessary.
- Check the PCM: If all the other components have been tested and the issue persists, there might be a problem with the PCM. However, this is quite rare, and it’s recommended to consult a professional mechanic to diagnose and repair the PCM if necessary.
Remember to clear the code after performing repairs and retest the system to ensure the issue has been resolved.

P0463 code on a Dodge Ram Tech Note
When diagnosing a P0463 code on a Dodge Ram, it is essential to keep in mind that the most common cause of this issue is a faulty fuel level sensor or damaged wiring.
Before diving into more complex diagnostics or replacing more expensive components, start with the basics. Inspect the wiring and connectors, test the fuel level sensor, and ensure the fuel gauge is functioning properly.
Additionally, note that fuel additives or contaminants in the fuel tank can sometimes cause erratic readings from the fuel level sensor, leading to a P0463 code.
If the fuel tank has recently been contaminated or additives were used, consider cleaning the fuel tank and replacing the fuel filter as part of your diagnostic process. However, always prioritize checking the common causes first, as mentioned in the table above.
Lastly, remember to clear the code after performing any repairs and retest the system to ensure the issue has been resolved. If the problem persists, consult a professional mechanic for further assistance.
P0463 code on a Dodge Ram possible symptoms and solutions
Table: P0463 code on a Dodge Ram possible symptoms and solutions
| Possible Symptom | Solution |
|---|---|
| Erratic or incorrect fuel gauge reading | Test and replace the fuel level sensor if necessary. Check the fuel gauge and wiring for issues. |
| Check Engine Light illuminated | Diagnose the cause of the P0463 code by following the suggested steps, repair or replace components as needed, and clear the code. |
| Poor fuel economy | If the issue is caused by a faulty fuel level sensor or fuel gauge, addressing these problems should help improve fuel economy. |
| Difficulty starting the vehicle | Fixing the fuel level sensor, fuel gauge, or any other related issue should improve the vehicle’s starting performance. |
| Running out of fuel unexpectedly | Resolving the issue with the fuel level sensor or gauge should help prevent unexpected fuel depletion. |
Keep in mind that these symptoms are not exclusive to a P0463 code, and other issues may cause similar symptoms. Always diagnose the issue thoroughly before performing any repairs.
P0463 code on a Dodge Ram description
The P0463 code on a Dodge Ram is a diagnostic trouble code (DTC) related to the fuel level sensor circuit. This code indicates that the powertrain control module (PCM) has detected an incorrect signal from the fuel level sensor, which is responsible for measuring the amount of fuel in the vehicle’s fuel tank and relaying this information to the fuel gauge on the instrument cluster.
When the PCM receives an erratic or implausible signal from the fuel level sensor, it triggers the P0463 code and illuminates the Check Engine Light. This issue may result in inaccurate fuel gauge readings, unexpected running out of fuel, or difficulty starting the vehicle, among other symptoms.
To resolve this issue, it is essential to diagnose the problem by inspecting the fuel level sensor, wiring, and connectors, as well as the fuel gauge and fuel pump module. Repair or replace faulty components as needed, and clear the code to ensure the problem is resolved.
How much does it cost to diagnose and fix the P0463 code on a Dodge Ram?
The cost to diagnose and fix the P0463 code on a Dodge Ram can vary depending on several factors, including the labor rates in your area, the specific cause of the issue, and the cost of replacement parts. Here’s a rough estimate of the costs involved:
- Diagnostic fees: The cost of diagnosing the P0463 code can range from $80 to $150, depending on the mechanic or dealership’s hourly labor rate.
- Fuel level sensor replacement: If the fuel level sensor is faulty, the replacement cost for the part itself can range from $50 to $150. Labor costs for this repair can range from $50 to $200, depending on the complexity of the replacement process for your specific Dodge Ram model.
- Wiring repair or replacement: If the issue is caused by damaged wiring, the cost can vary depending on the extent of the damage. Minor repairs might cost around $50 to $100, while more extensive repairs could cost several hundred dollars.
- Fuel gauge replacement: Replacing a malfunctioning fuel gauge can cost between $100 and $300 for the part, with labor costs adding another $50 to $150.
- Fuel pump module replacement or repair: The cost of a fuel pump module can range from $200 to $600, and labor costs can add another $100 to $300, depending on the model and the complexity of the job.
- PCM replacement (rare): Replacing a faulty PCM is an expensive repair and should be a last resort. The cost of a new PCM can range from $500 to $1,500, with labor costs adding another $100 to $300.
Please note that these are rough estimates and actual costs may vary depending on your location, specific vehicle model, and the severity of the problem. It’s always best to obtain quotes from multiple repair shops to compare prices and choose the most cost-effective solution.
