The latest model Duramax V8 6.6L engine is the L5P which is the newest diesel offered by General Motors. This V8 diesel is found in the Chevrolet Silverado and GMC Sierra and provides 445 horsepower and 910 foot pounds of torque.
The L5P engine is equipped with a new Denso common rail system. There are significant differences between the earlier model LML and the L5P. Fuel control starts with the low-pressure system which is equipped with a fuel pump driver module that is part of the CAN network. System charging is enhanced using the Body Control Module (BCM) to control system voltage and the use of a current sensor. The aftertreatment is installed at the outlet of the turbocharger. The DEF reductant injector continues to provide the fluid needed in the exhaust to reduce NOX emissions. Since this is not your traditional charging system, service of this system is of concern. The turbocharger has been changed with enhanced actuator vane control. Engine mechanical between the LML and the L5P are similar with service procedures changed.
This 1.5 hour webinar will instruct the attendee on the Duramax L5P, its subsystems and how it compares to early LML systems. There will be discussion on the L5D found on medium duty trucks and International applications. This information will include new diagnostic strategies and use of the scan tool. Service information discussion will cover typical Diagnostic Trouble Codes and service procedures.
Webinar Course Objective: Given the web presentation on the Duramax L5P platform, the attendee will have a general understanding of new service and diagnostic procedures for this engine.
