Hello! I have performed a complete timing job on my 2010 Fordf150, 5.4L 3v engine, 170k miles. Dropped oil pan and cleaned it. Replaced timing chains, tensioners, guides, and crank sprocket with Cloyes timing kit, replaced Cam phasers with new Ford phasers. Replaced vvt solenoids, cam position sensors, coil packs, new Melling 360 high volume oil pump, (oil pressure is great) 5w30 oil and Motocraft filter. After doing this, I crank the motor and get codes P0340 and P0345 (camshaft position sensor on each side. Engine starts, runs for a bit but real rough idle, then dies. I thought I did something wrong, so I did the timing again step by step. I still get the same codes after the second time around. I have good voltage to cam position sensors, and good continuity to PCM. I know I put timing chains on correctly matching the timing marks etc….I did remove camshafts and after putting them back in and putting timing parts in, then installed roller followers back in. But I still get these two codes, and the codes come back after I clear them, and engine runs rough. Not sure why. Driving me crazy!! Anyone have any ideas or suggestions? Terry.

 

I know you just wanted to do all this work, but if you had the problem before the work , suggest you check the cam sensor on the driver's side. Something is not right there. Either the wiring /connections or the sensor itself.

 

Thank you hanky for your reply. I didn't have these codes until after the timing job. The original codes were P0021 and P0022 so I replaced VVT solenoids and still had code P0021, so I decided on timing job. It was a lot of work for sure, and now I am left with this issue.

 

If it was not there before the work, just recheck your work. I believe it is involving that cam, sensor or wiring.
