    Truck runs fine. Seems like my turbo boost is little lower. What does this code stands for?

    IVA harness probably needs replaced. The engine will derate and cause the low boost.

    Mine's had this code for two years, but it runs ok and gets decent fuel mileage, so I've chosen to ignore it.
