What is CID 1025 & How to Solve It?

What is CID 1025:

cid 1025 indicates a problem with the vehicle’s exhaust gas recirculation (egr) valve circuit. this can lead to poor emissions control, engine stalling, or poor fuel economy.

‍

Why This Happens:

• faulty egr valve position sensor.
  
• carbon buildup in the egr valve.
  
• shorted or damaged wiring in the circuit.
  
• clogged or restricted exhaust passages.
  
• malfunctioning ecm interpreting sensor data incorrectly.
  
  

How to Fix It:

1. inspect the egr valve for carbon buildup.
   
2. test the egr valve position sensor voltage and resistance.
   
3. clean the egr valve and passages.
   
4. replace the valve or sensor if necessary.
   
5. clear the codes and reset the ecm.

‍

How to Avoid It Before It Happens:

• clean the egr system regularly.
  
• inspect wiring and connectors during scheduled service.
  
• monitor sensor data during diagnostics.
  
• clue’s fuel management services monitor egr systems to improve fuel economy and emission compliance.
