What is FMI 17 & How to Solve It?

What is FMI 17:

FMI 17 refers to sensor circuit range/performance issue. The ECM detects that the sensor is not operating within the expected range or its performance is degraded, which can lead to incorrect data being processed by the system.

‍

Why This Happens:

• Faulty or degraded sensor.
  
• Wiring or connector issues.
  
• Calibration error or misalignment.
  
• Environmental conditions affecting sensor performance.
  
• Power supply issues affecting sensor data.
  
  

How to Fix It:

1. Inspect the sensor for damage or wear.
   
2. Test the sensor’s range and performance against manufacturer specifications.
   
3. Check wiring and connectors for visible damage.
   
4. Recalibrate the sensor if required.
   
5. Replace the sensor if it continues to malfunction.
   
   

How to Avoid It Before It Happens:

• Regularly recalibrate sensors to maintain accuracy.
  
• Inspect wiring and connectors for damage or corrosion.
  
• Perform diagnostic checks to ensure sensor performance.
  
• Clue’s equipment maintenance services monitor sensor performance and help prevent range or performance issues from affecting engine operation.
