Misfire Diagnostics 2/8/25, Class #106 8:30-11:30 am Misfire issues are one of the most common problems technicians encounter. Pinpointing the exact type of misfire — whether it is a Mechanical, Ignition, Air-Fuel, or Density misfire — can be challenging. In this case study based class, we will discuss ignition, air:fuel and mechanical misfire testing procedures. We will also discuss modern day “ghost misfires”. Vehicles to be discussed include these (and more!): • 2015 Jeep Renegade 2.4L MultiAir Misfire • 2003 Ford Thunderbird 3.9L Misfire • 2016 Ford Edge 2.0L Misfire • 2019 Jeep Wrangler 3.6L Bank 2 Misfire

Diagnostic Strategies 2/8/25, Class #128 8:30-11:30 am
This session will enable technicians to interpret the information the scan tool provides for engine performance diagnostics. We establish a foundation utilizing “strategy-based diagnostics” to reduce diagnostic time and prevent emission related Check Engine light comebacks. We discuss utilizing scan tool information to gain diagnostic direction to repair today’s most seen Engine Performance concerns. After completing this class, techs will be able to: • Apply a logical flow of diagnosing Check Engine light concerns through understanding what the scan tool data is saying • Utilize the graphing function of the scan tool to ‘trend’ important scan tool PID (Parameter Identification Data) relationships • Diagnose emission related Check Engine light problems on vehicles through using generic and enhanced scan data analysis • Interpret important engine performance sensor information and vehicle operating system strategies
