What is CID 1057 & How to Solve It?

What is CID 1057:

CID 1057 refers to an issue with the exhaust gas pressure sensor. The ECM detects out-of-range readings that can impact turbo efficiency and exhaust backpressure control.

‍

Why This Happens:

• Faulty exhaust gas pressure sensor.
  
• Clogged sensor tubing from soot deposits.
  
• Broken or shorted wiring.
  
• Leaks in the exhaust manifold.
  
• ECM data interpretation fault.
  
  

How to Fix It:

1. Remove and clean the exhaust gas pressure sensor line.
   
2. Test the sensor for correct output signal.
   
3. Check wiring for continuity and connector corrosion.
   
4. Replace the sensor if readings remain inconsistent.
   
5. Verify exhaust manifold and piping for leaks.
   
   

How to Avoid It Before It Happens:

• Clean the exhaust sensor regularly.
  
• Avoid low-quality fuel that produces excess soot.
  
• Conduct periodic emissions system checks.‍
• Clue’s equipment maintenance services track exhaust system pressure to prevent turbo performance loss.
