Service engine soon light is on!

I bought my new F250 a few weeks ago and I love the truck...but now I have put 600+ miles on the truck and my service engine soon light came on. I just so happen to own a code reader, so I plugged it in and got an error code saying "cam position" which cannot be good.
</O
I just drop off the truck and the ford dealership were I purchased it and they contacted HQ and are sending an engineer out to look over the truck to find the problem and fix if possible.
<O
I will say this ford is taking the matter very seriously and have kept me in the loop the whole way so far.

<OAs soon as I hear more, I will pass on the information.<O

Welcome to FTE. Please keep us informed of what they find. The cam sensor is an issue with the old 7.3 trucks, but this is the first we've heard about it on the 6.7.

Just heard from ford, the engineer has run his tests on the engine and it is all good. He say it is a bad "cam positioning sensor" which they will be replacing tomorrow. After they replace the sensor they will run follow up tests on the engine to verify everything is working correctly. Still have my fingers crossed that is all it is. I will post another update tomorrow once the follow up testing is complete

As an owner of a 7.3 and one that has a 6.7 on order I sure hope I'm not going to be having a case of deja vu.

The CPS may be junk, but in terms of reliability, I really hope you do have a case of deja vu with the new 6.7. If the new motor earns the same reputation for reliability as the 7.3 has, then Ford hit a home run.

You are 100% right on that one.

I agree 1000%!! Just drove a 2011 f350 tonight and it was a great drive! Very comfy for just being an XL model. I'm just going to wait till issues might be worked out and to see if I can get a manual tranny!

I wouldn't be surprised if we see one of everything brake. They are going to build a few hundred thousand of these trucks, a dud part every now and then should be expected.

Now if we see someone post that the widget broke and 10-15 people on one forum say "me too", then we have issues. So far I can't recall any broken part with more than 1 or 2 having the same problem.

I think the strange transmissing shifting issue from 2nd to 3rd is the largest one so far and that's not many of us (maybe 6?).
I took mine in and they worked on it for several days and didn't find anything wrong so we'll have to see if Ford offers a computer update and that's probably all it is. It's documented so all I can do is drive it.

Cam position sensors go out on all motors. I had a Chevy 8.1 gasser that ate them. When it goes out, you're dead in the road with that motor.

With 600 miles on yours, it's just a bad part and hopefully they won't find that there was a production run of 1500 trucks with that same batch of sensors. If they do, it's an easy fix.

product testing is an art, not an exact science.. to make it a science, we would build 100,000 vehicles, measure them for 10 yrs.. fix all the issues, then start selling the fixed thing to customers.. not gonna happen..

you test a certain number (statistical sampling) of parts from a qualified supplier, and know that there is a percentage risk.. (on each part).. some risk impact is higher (cam sensor) than others (power seat switch), and you put that all in a big hopper of expectations, projections, guess and plan for it as best you can..

things WILL fail, warranty periods are calculated risks for all parties..

its an amazing discipline to figure all that out, and then add the world economy impacts on top!..

Well I got my truck back, everything tested out all right. The engineer said it was just a bad sensor.

I am very happy that is all it was.
