If you lift the hood of any newer vehicle, you can easily see that engine technology is getting more and more complex. Access for traditional engine condition tests is more difficult than ever before. Technicians with a good understanding of lab scopes and engine mechanical operation can learn to leverage the power of pressure transducers in their diagnostic routines with the information presented here. Pressure waveform readings from the intake manifold, combustion chamber and the exhaust stream can provide a wealth of information that can make difficult problems easy to find. Using logic and data acquired from multiple  points on a vehicle serve like pieces of a puzzle providing answers to the underlying fault.

This course covers the use of both absolute pressure transducers and delta pressure transducers and explains the characteristics and benefits of each type. This diagnostic approach will be demonstrated using real world examples and actual case studies. Each example demonstrates specifics of root cause analysis. Students will leave this class with confidence to invest in the tooling needed to perform pressure testing and analysis to improve their accuracy and efficiency to diagnose today’s vehicles.
