I am getting a code of P0406. I was told this was regarding the EGR Valve. what is the most common fix for this? and where is the EGR Valve? Do I need a book to find it and fix or can someone just look under hood and see it and see what part is broken or should I just replace whole egr valve? I am leaving in 2 weeks to take my kids camping PLEASE HELP! need to fix ASAP!

 

Replace the EGR, its on the front cylinder head about the alt.
