just bought a 2000 expedition eddie bauer has a check engine light,code,P1309. From everything I was reading the cam pos sensor is most likely the problem. I replaced it and it didnt fix it. I can read all values in the computer with my scan tool. Not sure what to look for, the truck runs good. Coolant temp in the computer is acurate, and the mass air is showing that its working but not sure if im not seeing something.Also the two hoses that go to the DPFE were bad, so I put new ones on but didnt help. The code comes back after I drive a mile or so. Any help would be appreciated
Need help please P1309
