Diagnostic code on Huyandai XG 350?

Reads insufficient exhaust gas recirculation. What does this mean and how do I correct it.What happens if i dont.|||it means what it says. it's part of your vehicles emissions.


your EGR valve could be faulty or is not opening up. a carbon buildup can also cause this and can be fixed by cleaning the valve or the tube.


a lack of vacuum can cause the valve not to open up properly.


you can test the voltage on the differential pressure feedback EGR sensor. you may need to replace that as well.


not sure what can happen over long term if not fixed.


there's also an actuator solenoid in the system.
