Class Next Week: Catalyst Efficiency Diagnostics with Tim Jones
This class lays out a logical, step-by-step plan focused on catalytic efficiency using scan data. Techs will learn how to prove the cause of P0420/P0430 while avoiding replacing oxygen sensors or other components.
Topics covered include:
✅ Catalytic converter purpose, function, and common failure causes
✅ Using scan data, freeze frame data, and mode six data to evaluate the PCM's diagnosis
✅ A diagnostic flow chart to help navigate testing
✅ Discuss chemically inefficient vs. physical restriction causing performance issues
✅ 2009 Subaru Tribeca P0420
✅ 2015 Hyundai Elantra P0420
✅ 2017 Honda Pilot P0420

Different manufacturers display and calculate load data differently; pressure values are also commonly misunderstood due to differences in how they are displayed. This class explains what load and pressure data represent, how to interpret those values, and when those PIDs should (and shouldn’t) influence your diagnostic process.
Discussion topics will include:
✅ What factors determine “engine load”?
✅ Defining engine load PID’s and how they are calculated
✅ What diagnostic value does the load PID have?
✅ Discuss the different types of sensors used to measure pressure
✅ Illustrate how to quickly convert the MAP data value for engine pressure\vacuum into useful values
✅ 2018 Honda Pilot transmission pressure case study

This class is part of our Technician Development Program schedule and is designed for new and less experienced technicians.

Join Tim Jones for a live online class focused on using fuel trims to diagnose driveability problems. Techs will learn how to analyze short term and long term fuel trim data, understand the relationship between upstream and downstream O2 sensors, and diagnose bad sensors, wiring issues, vacuum leaks, and misfires through real-world examples.
👉 Register here: https://automotiveseminars.com/product/fuel-trim-diagnostics-fundamentals/
Case Studies Covered:
✅ 2010 Hyundai Elantra 2.0L P0171 / P0170 / P2195 / P2414 / bad air fuel sensor
✅ 2014 Chevy Malibu 3.0L P0171 / P0191 / vacuum leak
✅ 2018 Ford F-150 2.7L EcoBoost P0306 / ignition misfire
✅ 2013 Honda CR-V 2.4L P0171 / contaminated fuel
✅ 2002 Chevrolet Suburban 5.3L P0300 / P0171 / intermittent misfire

Domestic Driveability Case Studies with John Thornton – live online class starts tonight at 7 PM CST. Case Studies Covered will include:
✅ 2015 Dodge Caravan P0841
✅ 2021 Ford F-150 2.7L Misfires
✅ 2021 Buick Encore 1.3L Turbo P1101
✅ 2018 Ford F-150 5.0L Cam Timing Concern
✅ 2019 Ford F-150 3.5L Cam Timing Concern
✅ 2017 Ford Escape 1.5L Eco4boost – is it a misfire or transmission concern?
Case studies are an effective way to explain system theory, testing techniques, and data interpretation in a real-world environment — and the concepts covered can be applied to many more makes and models than those featured in the case studies.
