have had this truck for two years had code p0402 when i got it. Sprayed egr rod? with wd-40 and worked it back and fourth with flat blade screwdriver, code went away. six months later code came back, sprayed it again code goes away. did this again yesterday,light went off after a couple of drive cycles. Will this damage the diaphram? will somthing else last longer?
