Turbocharger Operation and Diagnostics
We will discuss sensor inputs such as MAF (when used), Baro, MAP and boost (air charge). Also discussed will be wastegate valve and bypass valve controls.
The scan tool will be used exclusively for diagnostics, so data pid interpretation is an important part of this class. We will study WOT runs in order to evaluate turbo efficiency.
Discussion topics include the following:
- The Benefits of Boosting, and Intake Air Density
- Turbocharger Components
- 2011 Chevy Cruze Turbo Operation & P2261
- Ford F150 Twin Turbo 3.5L
- VW/Audi 2.0L Turbo & P0299
