'04 6.0 Powerstroke has code P132B
 

Does anyone know anything about this code? I've had this code recurring for awhile now. Replaced FICM (voltage was fluctuating) Replaced turbo (not getting any boost, sometimes). Dealer said this wa caused by exhaust leaks between manifold and turbo, I replaced all the pipes back there. This is really driving me nuts, someone out there has got to be able to help!
