Are you sure that P1698 and not P1693?

 

it may have been not sure, maybe i just read it wrong. I just thought it said P1698

---AutoMerged DoublePost---

no because i already have a P1693 code that came out with three others
they are P1693, P1694, P0602, P1698

 

Is that read with a scanner?

Unusual codes. Maybe dirt ECM or PCM connections?

Also check all your grounds on the truck (I think there are at least 7) but cant remember them all.

 

p1698- No bus message from TCM (transmission control modual)
something wrong with your TCM, how is your tranny working?
(Had the same thing with my truck, mechanics couldn't figure it out other than putting in a new TCM ($800). So i just did a tranny swap and put in a standard.
