Part of the problem is we never really know what the problem is unless we have a code reader that gives the same codes as what the dealer uses. I do have a old, cheap code reader that I used about a month before the Tyler trip. It that time, the CEL came on and I decided to try my old code reader. I forget now what the code was and what it was supposed to mean but I think it had something to do with fueling. I took it to my local Ford dealer who told me their diagnostics gave them a different problem than what I found. Ok, so on that trip they said it was the DEF sender, reservoir, and pump. A total of $1,908. Then the injector in Tyler which actually was a fuel problem makes me wonder about the first trip to the local dealer.

Are newer code readers better than one that is about 10 years old? Shouldn't all readers see the same code?

* On edit I think I have answered the question. HERE

I'm going to buy one of THESE It will be here tomorrow.
