Almost every driveability diagnostic requires the use of fuel trims which makes interpreting fuel trim values a critical skill for technicians. This class is all about giving you a sense of direction to solve fuel trim codes and issues.

The answers to these three questions will help you get started with Modern-day fuel diagnosics:
1. Under what operating conditions is the engine rich or lean?
2. Which cylinders in the engine are lean or rich?
3. Can you trust your fuel trim numbers?

Topics Covered
• Quickly identify under what conditions an engine is rich or lean.
• Determine if your fuel trim issue is single cylinder, one bank, or the entire engine.
• How to prove the PCM is doing the right thing and that the fuel trims are accurate
• Create a diagnostic direction with scan data clues.
• Using the load PID
• Diagnosing injector function with scan data
• Scan data clues to a bad MAF
• Recognizing the cause of fuel trim imbalances
• The importance of the rear oxygen sensor
• See how your scan tool can tell you what diagnostic tests need to be performed.

The instructor will demonstrate via case studies how to interpret and use fuel trims to diagnose a variety of rich & lean concerns.

BMW, Chrysler, Ford, GM, Nissan and Toyota case studies will be presented.
