Code P0464 Subaru Description
The P0464 code for Subaru vehicles indicates a problem with the fuel level sensor circuit intermittently malfunctioning. The fuel level sensor is responsible for sending information to the vehicle's fuel gauge to display the correct fuel level to the driver. When this sensor circuit is not functioning properly, it can lead to inaccurate readings on the fuel gauge, which can cause inconvenience for the driver and potentially lead to running out of fuel unexpectedly.
Common Causes of P0464 Subaru
- Faulty fuel level sensor
- Corroded or damaged wiring in the sensor circuit
- Poor electrical connection to the sensor
- Issues with the fuel pump module
- Fuel tank contamination affecting sensor readings
Symptoms of P0464 Subaru
- Inaccurate fuel level readings on the fuel gauge
- Fluctuating fuel gauge readings
- Check Engine Light illuminated
- Engine stalling or hesitation
- Difficulty starting the vehicle
How to Fix P0464 Subaru
- Diagnose the issue by using a scan tool to read the trouble code and test the fuel level sensor circuit.
- Inspect the wiring and connections related to the fuel level sensor for any damage or corrosion. Repair or replace as needed.
- Test the fuel level sensor itself to determine if it is functioning correctly. Replace the sensor if it is faulty.
- Reset the trouble code and test the vehicle to ensure the issue has been resolved.
- If the problem persists, further diagnostic testing may be required to identify any underlying issues with the fuel system.
Cost to Fix P0464 Subaru
The typical repair costs for addressing a P0464 code on a Subaru vehicle can range from $200 to $500, including parts and labor.

Frequently Asked Questions about P0464 Subaru Code
1. What does the OBDII code P0464 mean on a Subaru?
The P0464 code indicates an intermittent issue with the fuel level sensor circuit, meaning the vehicle's computer is receiving unreliable data about the fuel level.
2. What are the common symptoms of the P0464 code in a Subaru?
Symptoms may include erratic or inaccurate fuel gauge readings, the check engine light turning on, and possible difficulty estimating remaining fuel.
3. What causes the P0464 code to appear in a Subaru?
Common causes include a faulty fuel level sensor, damaged wiring or connectors in the fuel sensor circuit, or, less commonly, issues with the vehicle's powertrain control module (PCM).
4. Can I still drive my Subaru with a P0464 code?
Yes, you can typically continue driving, but you may not get accurate fuel level readings, risking running out of fuel unexpectedly.
5. How do I diagnose the P0464 code on my Subaru?
Use an OBDII scanner to confirm the code, inspect the fuel level sensor wiring and connectors for damage, and test the sensor for proper operation with a multimeter.
6. How do I fix the P0464 code on a Subaru?
Repairs may involve replacing a faulty fuel level sensor, repairing damaged wiring or connectors in the fuel sensor circuit, or, in rare cases, reprogramming or replacing the PCM.
7. How much does it cost to fix the P0464 code on a Subaru?
Costs vary, but replacing a fuel level sensor typically ranges from $200 to $500, including parts and labor. Repairs to wiring or connectors may be less expensive.
8. Can a bad fuel pump cause the P0464 code?
While uncommon, a failing fuel pump assembly that includes the fuel level sensor can contribute to this code if the sensor is integrated and malfunctioning.
9. Will clearing the P0464 code solve the problem?
Clearing the code may turn off the check engine light temporarily, but unless the underlying issue is resolved, the code is likely to return.
10. Is the P0464 code related to poor fuel economy?
This code itself does not directly affect fuel economy, but inaccurate fuel readings can make it harder to track usage effectively.
