Dmax 3,0 2007
 

Having problems with my 3.0 2007, getting error code P1404 after every start and it goes into limp mode, If you go in and reset the code, the car runs as it should until you turn it off, if you start it again, the code comes up. Checked the valve and cleaned the Egr. Tried another EGR too but same error code.
What should ido?
