Ignition Coil Diagnostics
Free
Problems ranging from misfires to no-starts can be related to ignition coil problems. Getting a C.O.P. (Coil-On-Plug) diagnosis right the first time can be difficult if you don’t have every trick and tip at your disposal. In this seminar, v...eteran Delphi instructor Dave Hobbs will bring you valuable information on secondary and primary resistance tests, easy ways to use common and popular tools to diagnose C.O.P.s, and how to leverage DTCs, Global OBD-II and Mode $06 data to enhance your diagnostics.

MAF and the Modern Tech
Free
Mass Air Flow Sensors (MAF) have been with us for decades, helping engine management systems know the precise volume and density of air the engine is breathing to provide the right fuel injector spray and correct spark timing. Faulty MAF se...nsors often set a Diagnostic Trouble Code (DTC) but that’s not always the case, leading to excess frustration in the service bay. In this one-hour seminar, veteran Delphi instructor Dave Hobbs will explain diagnostic strategies for technicians at every level of technical ability and show you how to sort out MAF problems from actual engine breathing problems using any scan tool and a simple volumetric efficiency calculator. Plus, learn about Do’s and Don’ts regarding MAF cleaning and replacement, and much more.
