Code P0463 2021 Honda CR-V Description
The P0463 diagnostic trouble code (DTC) in a 2021 Honda CR-V indicates a problem with the Fuel Level Sensor Circuit High Voltage. This code specifically points to an issue with the fuel level sensor in the vehicle's fuel tank. The fuel level sensor is responsible for sending information to the vehicle's engine control module (ECM) about the amount of fuel in the tank. When the sensor detects a high voltage in the circuit, it means that the fuel level is higher than it actually is, leading to inaccurate readings being sent to the ECM.
Common Causes of P0463 2021 Honda CR-V
- Faulty fuel level sensor
- Corrosion or damage to sensor wiring
- Poor electrical connection
- ECM software issue
- Fuel contamination affecting sensor readings
Symptoms of P0463 2021 Honda CR-V
- Inaccurate fuel gauge readings
- Check Engine Light illuminated
- Engine stalling or hesitation
- Reduced fuel efficiency
- Difficulty starting the vehicle
How to Fix P0463 2021 Honda CR-V
- Diagnose the issue using a scan tool to confirm the P0463 code and check the fuel level sensor's operation.
- Inspect the wiring and connections for any damage or corrosion. Repair or replace as necessary.
- Test the fuel level sensor's resistance and voltage to ensure it is functioning correctly.
- Replace the fuel level sensor if it is found to be faulty.
- Clear the code and reset the ECM to monitor the system for any recurring issues.
Cost to Fix P0463 2021 Honda CR-V

Frequently Asked Questions about P0463 2021 Honda CR-V Code
1. What does the OBDII code P0463 mean on a 2021 Honda CR-V?
P0463 indicates a "Fuel Level Sensor Circuit High Voltage," meaning the fuel level sensor is sending a voltage signal that is higher than expected to the engine control module (ECM).
2. What are the common symptoms of the P0463 code in a 2021 Honda CR-V?
Symptoms can include an inaccurate fuel gauge reading, the check engine light turning on, and difficulty determining the actual fuel level.
3. What causes the P0463 code to appear in a 2021 Honda CR-V?
Common causes include a faulty fuel level sensor, damaged wiring or connectors in the fuel sensor circuit, or a malfunctioning ECM.
4. Is it safe to drive with the P0463 code on a 2021 Honda CR-V?
While it may be safe to drive in the short term, you risk running out of fuel unexpectedly due to inaccurate gauge readings, which can be dangerous.
5. How do I diagnose the P0463 code on my 2021 Honda CR-V?
Start by checking the wiring and connectors for the fuel level sensor for damage or corrosion. Then, test the fuel level sensor's voltage output using a multimeter.
6. Can a bad fuel pump cause the P0463 code in a 2021 Honda CR-V?
While uncommon, a malfunctioning fuel pump assembly that houses the sensor may contribute to the issue if it affects the sensor's operation.
7. How can the P0463 code be fixed on a 2021 Honda CR-V?
Repairs may include replacing the fuel level sensor, repairing or replacing damaged wiring/connectors, or updating/reprogramming the ECM if necessary.
8. How much does it cost to fix the P0463 code on a 2021 Honda CR-V?
Repair costs depend on the cause but typically range from $150 to $400, including parts and labor, with fuel level sensor replacement being a common expense.
9. Will clearing the P0463 code solve the problem on my 2021 Honda CR-V?
Clearing the code will turn off the check engine light temporarily, but it won’t fix the underlying issue, and the code will likely return.
10. Can a low or empty fuel tank trigger the P0463 code on a 2021 Honda CR-V?
Yes, an empty or near-empty fuel tank can sometimes cause erratic readings from the fuel level sensor, potentially triggering the code.
