- Advanced Engine Mechanical Diagnostics
Mechanical, or base engine faults can be difficult to diagnose. Technicians can replace the wrong parts or spend a lot of wasted time on diagnosis when the cause of the problem lies inside the engine. With the introduction of advanced valve actuation systems, the difficulty faced by technicians has grown. Fortunately, new diagnostic tools and techniques are now available to make the job easier. The goal of this class is to prepare the aftermarket technician to use the appropriate tools to identify many base engine faults without engine teardown.
- Diagnosing Fuel Trim, MAF, and 02 Problems
The next vehicle you diagnose might be equipped with an Air/Fuel or Lambda sensor. These sensors have complicated the diagnosis of fuel trim DTC and reduced power concerns. Our familiar scan data such as g/s for a mass air flow sensor, Short Term and Long Term for fuel trim, 0-1 volt for O2 sensors have been replaced with terms like kg/hr, Equivalence Ratio, Milliamps, or strange voltages that don’t make sense. The goal of this class is to prepare aftermarket technicians to be able to streamline their diagnosis of fuel control related problems through an understanding of systems operation, and the application of data and diagnostic functions.
