P2067 Fault Code

Fuel Level Sensor B Circuit Low

• What does that mean?

• Causes
• Solutions

The P2067 fault code indicates an issue with the Fuel Level Sensor B Circuit, specifically that it is reading lower than expected. This sensor is responsible for measuring the fuel level in the fuel tank and transmitting that information to the engine control unit (ECU). A low reading could suggest a problem with the sensor itself, the wiring, or the connections involved.

What are the symptoms of the P2067 code?

Common symptoms of a P2067 fault code may include:

• Inaccurate fuel gauge readings (e.g., showing empty when there is fuel)
• Fuel level warning lights illuminating on the dashboard
• Engine performance issues due to improper fuel level readings
• Possible difficulty in starting the vehicle if the system believes the tank is empty

What causes the P2067 code?

Potential causes of a P2067 code include:

• A failing fuel level sensor
• Damaged wiring or connectors in the fuel level sensor circuit
• Poor ground connection affecting the sensor's operation
• Issues with the fuel tank itself that may affect the sensor's performance

How to fix P2067?

To resolve a P2067 error code, consider the following steps:

• Inspect the fuel level sensor and its circuit for any visible damage, including the wiring and connectors.
• Test the fuel level sensor to verify its functionality, and replace it if it is faulty.
• Check the ground connections and ensure they are secure and free of corrosion.
• Clear the fault code from the ECU and monitor the system to see if the code returns.
