P2069 Fault Code

Fuel Level Sensor B Circuit Intermittent

• What does that mean?

• Solutions

The P2069 fault code indicates an issue with the Fuel Level Sensor B Circuit. This code arises when the Engine Control Module (ECM) detects an intermittent malfunction in the fuel level sensor, which is responsible for measuring the amount of fuel in the tank. A healthy sensor sends a consistent voltage signal to the ECM, reflecting accurate fuel levels. When the circuit experiences interruptions or failures, it can lead to inaccurate readings and potential driveability issues.

What are the symptoms of the P2069 code?

Common symptoms associated with the P2069 fault code can include:

• Inaccurate fuel gauge readings
• Erratic fuel level indications on the dashboard
• Check Engine Light illuminates
• Possible engine stalling or performance issues due to incorrect fuel level information
• Difficulty in estimating fuel range.

What causes the P2069 code?

Possible causes for this fault code may include:

• Faulty fuel level sensor B
• Damaged wiring or connectors in the fuel level sensor circuit
• Poor ground connection
• Corrosion in the electrical connectors
• ECM malfunction
  These issues can lead to the sensor failing to provide a proper signal, causing an intermittent reading.

How to fix P2069?

To resolve the P2069 fault code, the following steps can be performed:

1. Inspect the wiring and connectors related to the fuel level sensor B for damage, corrosion, or loose connections.
2. Test the fuel level sensor B for proper operation using a multimeter, checking its resistance and voltage output.
3. Replace the fuel level sensor B if found faulty.
4. Verify ground connections for integrity and ensure no interruptions are present.
5. Clear the fault code using an OBD-II scanner and take the vehicle for a test drive to ensure the code does not return.
