well my truck has been acting a little screwy lately. One day i went to go shut it off and i had the key out and it was still running and i had to dump the clutch just to get it turned off. And it wasnt anything to do with my cool down timer with my attitude as i have never used it and it was off. It sat that day for 7 hours and when i drove home it had absolutely no power at all would only build about 3 psi of boost. At that time there were no codes and the check engine light wasnt on. Well when i got it home i disconnected the battery cables and put them back on and everything was fine for a week or so until i was driving again and now it wont build any boost at all sometimes...but other times it will be fine. Im getting a 1693 code and heres what i came up...The companion engine control module has shown a fault?? Can anyone help me out on whats wrong. Thanks!
