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.

Brandon your teaching technique is excellent. Ive watched your classes on several platforms now and each time you are able to hold my interest and concentration. Will sometimes get away from my understanding totally however thats the beauty of videos like this, i can now rewatch over and over and let the information sink in. Thanks to both yourself and Brin for taking the time to produce this series
Great presentation. It is helping me to better understand scope use. Showing the waveform through piston travel was very helpful. All those facebook sites show waveforms, but no one ever explains them. Thank you.
I really like the content. Thank you so much CTI and Mr. Brandon
One way to identify the correct Fluke PV350, that works with a scope, is to open the back up so the battery is exposed. Look next to the zero adjustment button. The good model has a little blue box in that area, the bad one doesn't. Credit to Super Mario diagnostics.

is this the same with PV500? I got this model and I could not see vacuum changes from the manifold, just a straight flat line.
You can tell on the pv350 with the little blue circuit inside I’ll send you a pic of thr difference. Pico now owns first look sensor now as well. Great presentation guys.
Good ol' Bernie Thompson says that a difference in towers halves of about 15-2deg is ok, and a if exhaust pocket is witin 2psi of intake pocket, that's ok ... any thoughts or experience to the contrary ... I reviewing an old capture on a good cyl that has a 15deg variation in tower halves, but the tower also has a pressure rise that is quicker than the expansion.
Thanks for some fantastic information
at 28:00 minute demonstrating ATS vacuum transducer on scope and applying vacuum to that sensor pulled the voltage down and applying pressure push voltage upward,i thought ATS vacuum transducer push the voltage up and a lower vacuum brings the voltage down,at least that is what i get when using the 30 inch vacuum transducer on e scope.
