What is CID 910 & How to Solve It?

What is CID 910:

cid 910 refers to a problem with the exhaust gas temperature (egt) sensor. inaccurate readings can cause improper fuel-air ratio adjustments or trigger regen system faults.

‍

Why This Happens:

• faulty egt sensor.
  
• soot buildup or contamination on the sensor tip.
  
• shorted or damaged wiring.
  
• failed ecm interpretation.
  
• exhaust leaks altering true temperature readings.
  
  

How to Fix It:

1. inspect the egt sensor for soot buildup.
   
2. test sensor voltage while the exhaust warms up.
   
3. repair or replace damaged connectors and wiring.
   
4. replace the sensor if readings remain off.
   
5. verify regen system functionality after repair.
   
   

How to Avoid It Before It Happens:

• clean exhaust systems routinely.
  
• avoid long idling to prevent soot accumulation.
  
• monitor egt data via diagnostics.
  
• clue’s fleet management software helps monitor exhaust health and prevent costly downtime.
