Help P1316 and P0238 Codes

[tcb1188]

I was driving to work this morning and was going over one of the stupid road humps in my neighborhood and when I came over it the truck started running rough with hardly no power and threw some codes. I went home and read the codes and took my program out. The codes are P1316, injector driver module codes detected, and P0238, turbo boost sensor A circuit high. I called the dealer and he said P1316 means a bad injector module and it costs $854.98. Does anyone have any ideas so that I dont have to go drop that much money? I had read it could be the short harness but I do not know where to check that.

Thanks

Todd
