What is FMI 2 & How to Solve It?

What is FMI 2

FMI 2: Refers to a fault code indicating that the sensor is reporting data that is below the expected value, which means the ECM is receiving lower-than-expected readings from the sensor.

FMI 2 signals that the sensor is not functioning within the expected parameters, potentially leading to inaccurate readings and performance issues.

‍

Why It Happened

This fault code is commonly caused by:

• A malfunctioning sensor.
  
• Wiring issues or poor connections between the sensor and ECM.
  
• Environmental conditions affecting sensor accuracy.
  
• A fault in the ECM processing the sensor’s data.
  
  

How to Resolve It

To resolve FMI 2:

1. Inspect the sensor and wiring for damage or wear.
   
2. Replace the faulty sensor if necessary.
   
3. Check for any loose or corroded wiring connections.
   
4. After repairs, clear the fault code and restart the engine.
   
   

How to Avoid Before It Happens

To prevent FMI 2:

• Regularly inspect the sensor and wiring.
  
• Keep the sensor clean and free from contaminants.
  
• Use Clue to monitor sensor data and receive alerts for sensor-related issues.
