Alright long story short. I am coming home on leave, my dad told me that my trucks service engine light was going on and off. So i am trying to trouble shoot it over the phone to my baby brother (15yrs, he’s pretty inclined for his age).

He told me that he was getting two codes. ON/OFF ignition method.
0237-P0237 Turbo/Super Charger Boost Sensor A Circuit Low
1693-this one from my reading/memory means there are other codes.

Before i left my truck with my folks i had had some trouble with my XZT+ getting a tune installed i chalked it up to having Windows Vista, and eventually thought i had it worked out because it ran fine and did not through any codes for the last week i was home. Now it’s been sitting in a barn and occasionally getting driven.

Alright so what you all think.
Thanks
ROB

 

Try taking the box off. The boost fooling feature would play with that circuit and might be causing the problem.

 

Talking over the phone to my brother he unpluged and then replugged the box, then my father and him had to drive some 450miles with it. Supposedly the service engine light hasnt come back on.

I will see when i get home this saturday. Cant wait ive been away for almost 6 months.

Thanks
Rob

 

if the box isn't functioning properly, you'll get some boost codes.
