Description
Learn how GDI systems work and how to diagnose them with confidence. This class covers injector control, power and ground testing with lab scopes and amp probes, and smart sensor diagnostics for fuel pressure, temperature, and throttle position. You’ll also learn how to test high-pressure pumps using scan data and scopes. We will also cover full section on injector testing includes leak, spray pattern, volume, and timing tests.
Topics Covered:
- Design, Operation, and Diagnostics of GDI Systems
- Charge Pump and Boost Capacitor Operation
- How the PCM Interacts with the GDI System
- System Testing with Lab Scopes and Amp Probes
- Smart Sensor Systems
- High Pressure Pump Operation and Testing
- Injector Testing Methods
