What is CID 995 & How to Solve It?

What is CID 995:

cid 995 refers to a fault in the exhaust gas recirculation (egr) temperature sensor circuit. inaccurate readings cause poor emissions control and engine performance drops.

‍

Why This Happens:

• faulty egr temperature sensor.
  
• soot clogging the egr passage.
  
• damaged wiring or open circuit.
  
• loose connectors.
  
• ecm misinterpretation of temperature data.
  
  

How to Fix It:

1. remove and clean the egr sensor and passages.
   
2. test the sensor’s voltage output while heating.
   
3. inspect wiring and connectors for continuity.
   
4. replace the sensor if readings remain unstable.
   
5. clear codes and verify emissions compliance.
   
   

How to Avoid It Before It Happens:

• clean the egr system periodically.
  
• perform diagnostic temperature checks.
  
• use low-ash engine oil to minimize soot buildup.
  
• clue’s equipment maintenance services track egr health and ensure emission sensors remain functional.
