What is CID 916 & How to Solve It?

What is CID 916:

cid 916 refers to an issue with the exhaust gas recirculation (egr) valve position sensor. the ecm detects that the egr valve is not moving as commanded, which can cause high emissions, rough idling, or loss of power.

‍

Why This Happens:

• faulty egr valve position sensor.
  
• carbon buildup preventing egr valve movement.
  
• damaged wiring or shorted circuit.
  
• corroded electrical connectors.
  
• ecm misinterpreting valve position signals.
  
  

How to Fix It:

1. inspect the egr valve for sticking or clogging.
   
2. clean carbon deposits from the valve and passages.
   
3. check wiring and connectors for corrosion or wear.
   
4. test valve response with a diagnostic scanner.
   
5. replace the egr valve assembly if necessary.
   
   

How to Avoid It Before It Happens:

• perform regular egr system cleanings.
  
• avoid low-speed idling for long periods.
  
• inspect wiring and connectors routinely.
  
• clue’s equipment maintenance services help monitor egr systems to prevent clogging and engine performance issues.
