so i threw a CEL P401 soooo here are the 6 things it could be
EGR valve stuck closed open or short in VSV circuit for EGR Vacuum or EGR hose disconnected MAP sensor EGR VSV open or closed malfunction ECM What is ECM and VSV? i can check the hoses and like a dirty MAP sensor (can i have a dirty EGR valve hence the closed?) i know you have to clean with non corrosive stuff (no brake cleaner) what does anyone recommend? how do i know when its fixed, i know you can disconnect battery to reset computer and get rid of CEL or does the CEL go away after its fixed then disconnect to reset. Any thoughts appreciated. |
