What is CID 1059 & How to Solve It?

What is CID 1059:

CID 1059 identifies a fault in the crankcase pressure sensor. Incorrect readings can cause ventilation issues and affect engine oil separation systems.

‍

Why This Happens:

• Faulty crankcase pressure sensor.
  
• Clogged breather system.
  
• Damaged or shorted wiring.
  
• Oil contamination on the sensor.
  
• ECM processing errors.
  
  

How to Fix It:

1. Inspect the crankcase ventilation system for blockages.
   
2. Clean or replace the crankcase pressure sensor.
   
3. Check wiring and connectors for integrity.
   
4. Replace damaged hoses or filters.
   
5. Clear codes and test system pressure readings.
   
   

How to Avoid It Before It Happens:

• Maintain the crankcase ventilation filter.
  
• Avoid overfilling engine oil.
  
• Inspect and clean the pressure sensor regularly.‍
• Clue’s equipment maintenance services help track crankcase ventilation to ensure clean engine operation.
