Coolant temperature sensor (Primary & Secondary ECM)
Intake manifold air temperature sensor (Primary & Secondary ECM)
Engine oil temperature sensor (Primary ECM)
Turbocharger inlet temperature sensor (Primary ECM)
SCAC temperature sensor (Primary ECM)
Transmission temperature sensor (Primary & Secondary ECM)This engine utilizes a redundant control system in the case of an ECM failure. If the primary ECM fails, the
