What is SPN 560 FMI 19 & How to Solve It?

What is SPN 560 FMI 19:

SPN 560 FMI 19 indicates a low voltage condition in the Oil Pressure Sensor Circuit. FMI 19 means that the ECM is receiving a signal that is below the expected range from the oil pressure sensor, which could lead to improper oil pressure readings and affect engine lubrication.

Why This Happens:

• Faulty oil pressure sensor.
  
• Shorted or damaged wiring in the sensor circuit.
  
• Loose or corroded sensor connectors.
  
• Low oil pressure due to a malfunctioning oil pump.
  
• ECM misinterpreting the sensor’s signal.
  
  

How to Fix It:

1. Inspect the oil pressure sensor and wiring for damage or malfunction.
   
2. Test the sensor’s voltage and resistance to ensure proper operation.
   
3. Check connectors for tightness and cleanliness.
   
4. Replace the faulty sensor if necessary.
   
5. Ensure the oil system is functioning properly and maintaining adequate pressure.
   
   

How to Avoid It Before It Happens:

• Regularly inspect the oil pressure sensor and its wiring.
  
• Maintain proper oil levels and perform regular oil system maintenance.
  
• Keep connectors clean and corrosion-free.
  
• Perform routine diagnostic checks to monitor oil pressure.
  
• Clue’s Equipment Maintenance services ensure oil pressure systems remain stable and prevent failures from affecting engine operation.
