hi guys,
i have had my hypertech installed for about a month now and i plugged my code reader in just for curiousity sake no light or anything, but i was surprised what i found 3 codes P0216 injection timing control circuit malfunction, P0602 control module Programming error, P1693 Auxilary imputs, Auxilary outputs. Is this normal just due to the tuning??? is that how a dealer can tell it has a tuner?? Truck runs fine I am just curious can i delete these or not???

 

i have a hyper tech max energy and i havent gotten any of those. all i have gotten are P1689 &1690 & a P0230? all LP and IP codes, and i only went to stage 2. i didn't want to break anything so i stayed away from stage 3

 

uh oh, P0216 thats the death code of the VP44. i recommend you check your lift pump pressure immediately. does the truck start up fine ?

 

yea truck starts and runs fine your kidding me hope the vp44 is not trashed

 

called dealer they said it could probably just be what they call false codes due to the programming

 

yes that is a way they can find out that you had a programmer on it (it throwing codes)
