Hi Forum, I am getting a P0404 code on my 98 C1500. I changed the EGR valve a year ago. I cleaned the valve but it seemed to move freely and was not too heavy with carbon buildup. I want to make sure I don't have an issue with the wiring. How do I test the wire connections and what should the wire colors be? The EGR connector wires appear to have different colors than my Haynes Manual. There are no letters on the EGR valve or the connector.
