Don Knight :

Both of these are fairly easy repairs if you have the correct tools.The fan relay is usually just a matter of replacing the relay.As for the egr valve,you would be better off letting a mechanic check the system before replacing any parts.Your back pressure transducer can cause this code and not the egr valve itself.I always test before replacing parts because it is not good to charge the customer for throwing parts on an engine till you hit the right one.Please let me know if you need more assistance,Don
