P0017 and ECM-671C after Timing Belt

Alexjordan22 · Post by **Alexjordan22** » 02 Jun 2026, 05:43

2005 2.5t which I recently bought needed the exhaust VVT hub replaced. It was due for a timing belt so got it done. I followed the write up posted by F250 for the hub install and thought I did everything right, but now I have this CEL and the P0017 code. I hooked up Vdash and it had the ECM-671c "Camshaft Position, exhaust. High."

I think I'll go in and line up the timing marks and check them again, but I'm worried I will find that I'm not off a tooth and I wont know what else to do.

Ive seen people use Vida and can see their camshaft degree. I have been having a difficult time trying to get Vida installed on my Windows 11 laptop so maybe I'll have to look into that more. Any suggestions are appreciated

Make sure you are using cam locking tool for this job. Watch some YouTube videos on how to properly do this procedure(i would be even willing to use a crank lock tool after this experience). Make sure you are "loading" VVTs.
