What is SPN 6713 & How to Solve It?

What is SPN 6713:

SPN 6713 indicates a fault with the Turbocharger Compressor Outlet Temperature Sensor Circuit Malfunction. This sensor monitors the temperature of the air exiting the turbocharger compressor. If the sensor circuit malfunctions, it can lead to inaccurate temperature readings, potentially causing poor engine performance and affecting emissions control.

‍

Why This Happens

Common causes include:

• Faulty or damaged turbocharger compressor outlet temperature sensor.
  
• Wiring issues such as broken, corroded, or loose connectors.
  
• Sensor contamination or physical damage.
  
• Faulty Engine Control Module (ECM) or calibration errors.
  
  

How to Fix It

To resolve this fault:

1. Inspect the turbocharger outlet temperature sensor and wiring for damage or corrosion.
   
2. Test the sensor signal and replace the sensor if faulty.
   
3. Repair or replace damaged wiring or connectors.
   
4. Clear the fault code and verify temperature readings and engine performance.
   
   

How to Avoid It Before It Happens

Prevent this fault by:

• Regularly inspecting the turbocharger temperature sensor and wiring.
  
• Maintaining clean sensor connections and avoiding physical damage.
  
• Performing routine diagnostics to detect sensor issues early.
• Use Clue’s Reports & Analytics to track diagnostic codes and sensor performance, helping identify trends and potential issues with the turbocharger temperature sensor early.
