Diesel Talk: Powerstroke 6.7L
Webinar Course Objective:
Given the service information, tools and vehicle, the technician will follow a diagnostic strategy to repair and service various driveability issues found on a Ford truck equipped with the Powerstroke 6.7L engine.
The course will cover the description and operation of the Powerstroke 6.7L diesel engine found on Ford trucks starting in model year 2011. This engine has been designed with reverse flow cylinder heads, two cooling systems and a Bosch piezo common rail fuel injection system. The vehicle is also equipped with an extensive aftertreatment system for emission control. Tony Salas, training instructor, will cover the description and operation of the following subsystems:
• Engine design and repair procedures to follow
• Low- and high-pressure common rail fuel injection system, what is with the CP4 pump failures?
• Turbocharger variances through 2019 models, understanding boost control and intake flow
• Cooling systems, differences between primary and secondary cooling
• EGR operation and flow, operation, and service
• Network and communications, understanding the common failures with CAN
• Aftertreatment, how to deal with SCR (DEF fluid) issues
Mr. Salas will emphasize the importance of using service information and procedures. He will display live scan data using IDS Ford scan tool and review case studies. Bi-directional controls and typical PIDS will be taught.
Course training will include electrical and pressure testing of the subsystems of the Powerstroke 6.7L diesel engine. This includes understanding the permanent code and aftertreatment issues brought about by fuel and oil additives. Training will include proper engine oil and fuel filter maintenance. Given this is a webinar, there will be recorded video of the engine and scan data.
