FREE Training in NW Indiana 11/12 and 12/12
Hi everyone! I will be doing two more classes this year for the Indiana EPA. To RSVP call … Classes held from 6 p.m. to 10 p.m. at Envirotest Systems Headquarters 1171 Breuckman Dr., Crown Point, IN 46307, parking in back of building, enter through “Unit C”. Dinner will be provided.
AIR-FUEL & OXYGEN SENSOR DIAGNOSIS - Tuesday, November 12, 2019
Air-fuel sensors are commonly used by most OEMs for fuel control. This class will cover the theory and operation of air-fuel sensors compared to oxygen sensors. An overview of cylinder imbalance codes and monitor strategies will be introduced. Oxygen sensor voltage codes have quickly become the new rich/lean codes in emissions failures. This class will use case studies to show the various failures that can cause oxygen sensor voltage codes and how to determine if the sensor itself is skewed. A combination of scan tool data analysis and component level testing will be covered in detail with case studies of air-fuel and oxygen sensor failures. Fuel trim analysis, combustion analysis, and fuel system status will be covered in detail throughout the course.
COMPONENT LEVEL TESTING - Thursday, December 12, 2019
The computer control process of input - processing - output - feedback will be covered. When one of the components in this process fails it can have a chain reaction on the system and cause codes unrelated to the actual failure. OEM flow charts often lead to frustration or misdiagnosis of these systems. This class will help technicians determine where in the process the failure occurred and how to test that component. Sensors and actuator testing will be covered in detail including the electronic circuitry, switched power vs switched ground, and modulation. The component level testing will include scan tool data, DMM, test light, gauges, DSO, and other methods to accurately test the system. Case studies of various failures will show how this diagnostic process can be applied on the vehicle.
Yes, it is part of the Indiana EPA emission program. Anyone is welcome to attend, IL and IN residents/shops. The testing contractor pays me directly for the classes, no sponsorship or sales pitch... just training :-)
Wow that cool i will check it out Thank's for reply
Not a problem. There are a lot of techs in both Illinois and Michigan that fix Indiana emission failures. Hope to see you there!
Some of the content has been in prior classes, but most of it is new and not been presented before. I have developed some new drawings and animations to help techs with the most common struggles I see. Proper tool selection, lead placement and understanding test results will be covered in depth.
Sorry I was wondering if the Indiana EPA has sponsored these classes before. Seems like a good idea for state sponsorship. Especially in my ”Green state” of Washington that is ending emission testing at the end of this year.
Yes, they have been doing them for quite sometime. Technician training is supposed to be a part of the state's testing program. Actually, the cost of training actually saves tax payers money overall by avoiding unnecessary re-tests and man hours dealing with cars that cannot pass.
That's awesome I will call them monday thank you for letting us know.
Just called and signed up. Thanks Matthew!
