What is FMI 13 & How to Solve It?

What is FMI 13:

FMI 13 refers to open or short circuit in sensor circuit. The ECM detects a fault in the sensor’s wiring, either an open circuit or a short circuit, preventing the proper transmission of signals.

‍

Why This Happens:

• Damaged or broken wiring.
  
• Short circuit or ground fault.
  
• Loose or corroded connectors.
  
• Malfunctioning or failed sensor.
  
• ECM misinterpretation of the signal.
  
  

How to Fix It:

1. Inspect the wiring for any visible damage or short circuits.
   
2. Test the circuit for continuity and resistance.
   
3. Clean or replace damaged connectors.
   
4. Replace the faulty sensor or component if needed.
   
5. Ensure proper grounding and power to the sensor.
   
   

How to Avoid It Before It Happens:

• Perform regular wiring and connection checks.
  
• Use protective coatings on wiring to avoid corrosion.
  
• Ensure that connectors are tight and secure.
  
• Clue’s equipment maintenance services monitor wiring systems to prevent open or short circuit issues.
