This seminar will use case studies to help drivability technicians streamline their diagnostic approach to common yet difficult to diagnose engine performance concerns. Emphasis will be on scan tool data interpretation of fuel trim parameters used to identify and solve engine performance problems. Several cause and effect relationships will be discussed that lead to lean and rich engine running faults, exhaust sensor (O2 and Air: Fuel) faults and engine misfire concerns of all types, including variable valve timing related faults.
This seminar will cover:
• Air: Fuel sensor operation and testing
• Variable valve timing
• Pressure transducer waveform analysis
• How to diagnose fuel trim DTCs (P0171/P0174 – P0172/P0175) in a timely manner
• Volumetric efficiency testing to validate engine breathing concerns and sensor input accuracyRegister Now and Choose This CourseEnter code
