High-Pressure Common Rail (HPCR) fuel systems demand a systematic diagnostic approach and a thorough understanding of how each component interacts. This advanced training course provides proven diagnostic procedures that help technicians identify High-Pressure Common Rail (HPCR) fuel system failures quickly and accurately.

To maintain the performance and reliability of the HPCR systems, regular diagnostics are crucial. Our state-of-the-art diagnostic techniques help identify and resolve issues before they lead to significant engine problems. This class focuses on real-world testing techniques using scan data, pressure testing, electrical testing, and oscilloscope diagnostics. This class is for the diesel technicians who want to diagnose faster, test smarter, and solve complex fuel system problems with confidence.

Class Coverage:

• Pressure testing along with Scan-Data and electrical diagnostics.
• Both the Vacuum type as well as the Pressure style.
• High-Pressure injection pump’s Supply, Return, and Delivery fuel systems.
• Hydraulic and Electrical sides of the Fuel Control Solenoid.
• Common Rail, Pressure sensor and Fuel-limiting valve, require electrical testing.
• HPCR Fuel Injectors come in two styles, both of which are covered.
• When diagnosing any Injector, you must test its Supply and Return fuel. In order to inject fuel both are required for the Hydraulic Coupling that takes place internally.
• The ECMs’ electrical control of the Injector will be covered using a Scan Tool and a Digital Storage Scope (DSO).
• The injection must be timed correctly for Power and Torque to the engine. Testing Crankshaft and Camshaft position sensors are critical for any diagnostic procedures.
• Fuel temperature is a huge factor in the combustion process, so temperature sensors and diagnostics will be covered.
• Accurate injector diagnosis requires testing both the supply and return fuel circuits. We’ll explain how these circuits work together to create the injector’s internal hydraulic coupling and what the test results reveal.
