I picked up an 04 F150 to give my father for Christmas. It's got codes P0345 and P0054. I replaced the cam position sensor and cleared the codes but P0345 came back after 2 key cycles. The connector looks a bit boogered up but I would think it should work. I didn't mess with the 02 sensor yet but I looked at the wiring diagram and the grey/red wire from the 02 sensor and CP sensor are connected in the diagram. Anyone know where I should look?

 

What engine in this truck?

 

It's the 5.4 Triton.
