i put on a new egr valve on and i put 50 miles on the vehicle the check engine light came back on setting a code po 401 i need a diagram of the vacum lines going to this chyrsler town and country van egr system could i put a vacum line in the wrong place to set this code.
did you unhook battery when installing it,any electicral part being replacedhas a coad stored in computer ifthis is not done it will throw a false ses light,unhook battery for 10 min rehook,also recheck that you got plugin in tight,as for a vac line it has none or 1.
papa thanks for the tip. i think the car is loosing it's cat, and sending particles into the exhaust system. rapidjake
