Ford EcoBoost & Dual Fuel Diagnostics

Saturday, November 16. 2024

The real path to diagnostic success involves starting with what each system is actually trying to accomplish, how each monitor verifies operation, and how you can duplicate and measure it in the shop. On Ford vehicles, this is more challenging because flow charts cover groups of vehicles, not specific systems. The variety and complexity of Ford's engine management & emissions systems dictates the need for a more of a 'why' approach to system types, defaults and interactions. This new Ford seminar sorts through the hundreds of PIDs, controls, waveforms, and strategies available on modern Fords to find the best combination of Scan Tool, Lab Scope, and other tests for the most common diagnostics. More than that, it offers a high level thought process to determine which tests to perform, and just as importantly, which tests to avoid. Specific topics include:

• High Level Indicator tables for breathing & fueling diagnostic decision
• EcoBoost vacuum & pressure wastegates
• EcoBoost electronic wastegates
• EcoBoost duct vs. turbo bypass systems
• MAP vs TCBP boost control
• Dual fuel port/direct injection systems
• Identifying port/direct usage and failure modes
• Port vs. Direct Fuel Trim
• Three GDI fuel volume solenoid control variations
