What is CID 1056 & How to Solve It?

What is CID 1056:

CID 1056 points to a malfunction in the exhaust gas recirculation (EGR) temperature sensor circuit. The ECM detects temperature readings that are not within expected limits, impacting emissions control.

‍

Why This Happens:

• Faulty EGR temperature sensor.
  
• Carbon buildup restricting exhaust flow.
  
• Damaged or shorted wiring.
  
• Loose or corroded connectors.
  
• ECM misinterpretation of sensor data.
  
  

How to Fix It:

1. Inspect the EGR system for carbon buildup.
   
2. Test the temperature sensor for accurate readings.
   
3. Clean or replace the EGR sensor if required.
   
4. Check wiring and connector integrity.
   
5. Clear fault codes and perform EGR system diagnostics.
   
   

How to Avoid It Before It Happens:

• Use quality fuel to minimize soot buildup.
  
• Regularly clean EGR components.
  
• Keep electrical connections dry and corrosion-free.‍
• Clue’s equipment maintenance services help monitor EGR systems to maintain emission efficiency.
