    I’ve been to the mechanic three times but I still have had this issue. Some of the faults were light bulbs so I dropped them. The faults I have are now:

    1. inlet manifold pressure failed high

    2. engine air intake pressure-data erratic

    3. ambient and inlet manifold pressure difference

    4. controller #1 current below normal or open circuit
    I’ve already seen a mechanic, who talked me into replacing the temperature intake sensor, I have two on each side, so I replaced them. I also replaced the turbo boost sensor, just in case, and nothing changed

    After replacing the sensors I haven’t cleared the faults by the computer. I also should mention that I have an EJR bypass (deleted). The truck is losing power now, I couldn’t find any inter-cooler leak. However, some me can antics say it’s possibly a wire short or the computer. I’ve been to them many times and know how it goes where you just keep replacing things again and again. I hope someone can give me some advice on this issue.

    I want to try to fix this myself, but if anyone knows a good mechanic in the charlotte area as well, let me know. Thank you!
