    Have a 2012 cascadia with a dd13 engine and there is a loss of power. Starting from the turbo I have change the actuator, turbo speed sensor, dozzer head, dozzer injector, replaced my air to air, troubleshot the egr valve works fine, checked for boost leaks none found, nox inlet and nox outlet sensors, def filter, baked the dpf filter, checked all the def lines for blockage, check injectors, check fuel pump, and finally a software update on my computer and still no power, I'm starting to think it's maybe the Throttle position sensor or accelerator pedal position sensor? Please help it so been about 6 months with this issue about 5 different mechanics including the freightliner dealer and no one can seam to figure it out.

    take your truck to Detroit diesel dealer and ask them to check it. most likely fuel mapping related problem .

    He’s still a member, but doesn’t come here often.

    On a second thought, maybe he requested his account to be closed. Who knows.

    I asked a mod, they confirmed he's been banned.

    Wow. What did he do? He’s a cool guy in my opinion. He might be back. A ban isn’t always permanent.
