What is MID 108 & How to Solve It?

What is MID 108:

MID 108 refers to an issue with the Fuel Temperature Sensor Circuit. The ECM has detected an abnormal signal from the fuel temperature sensor, which can affect fuel management and lead to improper fuel temperature readings, potentially causing engine performance issues or poor fuel economy.

‍

Why This Happens:

• Faulty fuel temperature sensor.
  
• Shorted or damaged wiring in the sensor circuit.
  
• Corroded or loose sensor connectors.
  
• Incorrect power supply to the sensor.
  
• ECM misinterpretation of the sensor’s data.
  
  

How to Fix It:

1. Inspect the fuel temperature sensor for visible damage or malfunction.
   
2. Test the sensor’s voltage and resistance to ensure it is within manufacturer specifications.
   
3. Check wiring and connectors for visible damage or corrosion.
   
4. Replace the faulty fuel temperature sensor if necessary.
   
5. Ensure stable power supply to the sensor.
   
   

How to Avoid It Before It Happens:

• Regularly inspect the fuel temperature sensor and its wiring.
  
• Keep connectors clean and corrosion-free.
  
• Ensure proper power supply to the sensor.
  
• Perform routine diagnostic checks to monitor sensor performance.
  
• Clue’s Fuel Management services proactively monitor fuel temperature sensors to detect issues before they impact engine efficiency.
