What is SPN 560 11 & How to Solve It?

What is SPN 560 11:

SPN 560 11 refers to an issue with the Engine Oil Pressure Sensor Circuit. This fault typically occurs when the ECM detects that the voltage from the oil pressure sensor is out of range, potentially causing improper oil pressure readings and leading to engine damage or poor performance.

‍

Why This Happens:

• Faulty engine oil pressure sensor.
  
• Damaged or shorted wiring in the sensor circuit.
  
• Loose or corroded sensor connectors.
  
• Low oil pressure due to a malfunctioning oil pump.
  
• ECM misinterpreting the sensor's data.
  
  

How to Fix It:

1. Inspect the oil pressure sensor and wiring for any visible damage.
   
2. Test the sensor’s signal to ensure it matches manufacturer specifications.
   
3. Check the 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 engine oil pressure sensor and wiring.
  
• Perform routine oil system maintenance, including replacing filters.
  
• Keep connectors clean and free from corrosion.
  
• Monitor oil pressure during routine diagnostics.
  
• Clue’s Equipment Maintenance services can monitor oil pressure systems to detect early signs of failure and prevent engine damage.
