What is SPN 3510 & How to Solve It?

What is SPN 3510:

SPN 3510 refers to a problem with the Exhaust Gas Temperature (EGT) Sensor. This fault typically occurs when the EGT sensor provides an out-of-range signal to the ECM, affecting the exhaust after-treatment system and engine operation.

‍

Why This Happens:

• Faulty exhaust gas temperature sensor.
  
• Shorted or damaged wiring in the sensor circuit.
  
• Loose or corroded sensor connectors.
  
• Exhaust system malfunction or contamination.
  
• ECM misinterpretation of the sensor’s data.
  
  

How to Fix It:

1. Inspect the exhaust gas temperature sensor for visible damage.
   
2. Test the sensor’s signal to verify it is within manufacturer specifications.
   
3. Inspect wiring and connectors for damage or corrosion.
   
4. Replace the faulty sensor if necessary.
   
5. Inspect the exhaust system for contamination or blockage.
   
   

How to Avoid It Before It Happens:

• Regularly inspect the EGT sensor and its wiring.
  
• Keep connectors clean and free of corrosion.
  
• Perform routine exhaust system checks to avoid blockages.
  
• Use diagnostic tools to monitor sensor performance.
  
• Clue’s Equipment Maintenance services help monitor exhaust temperature sensors to prevent issues before they affect engine operation.
