Re: EGR Valve-99GTP

P0405 DTC indicates that the EGR valve position sensor circuit has low voltage so it is probably more electrical than a mechanical issue with the EGR. Diagnostics has detected the pintle position feedback circuit is either open or shorted to ground. You can try cleaning the mechanical part of the EGR valve but it probably won't do much good.

Also, check the electrical connector to the EGR for any bad wires or flaky connector.

And welcome to the forum and AF.
