The egr valve is located at the end of a hose that plugs into youe valve cover. It is pushed right into a rubber grommet that is located in one of the valve covers. I hope this helps. don.t forget to rate my nswer, thanks

You could have a restriction in the egr ports. remove the valve. Plug the holes, start engine. 1 hole will be blowing out exhaust, the other will have large vacuum.

did you clean the EGR passages? take the valve back off. one hole will have exhaust, the other should have strong vacuum.ususally the passage gets plugged with carbon, from the valve to where it goes into the intake manifold. you may take a wire and carb cleaner to clean the passage.

404 is exhaust gas recirculation circuit, and 405 is exhaust gas recirculation sensor circuit low. EGR sensor or ground?
