Course Title: Exhausted! Oxygen and Air Fuel Sensor Diagnostics

Course Description: 

Oxygen sensors have been in vehicles since 1976, yet we still struggle with their application and diagnostic powers. Exhausted takes you through the evolution of single wire oxygen sensors all the way up to modern air fuel sensors. Learn how to diagnose both systems quickly and effectively with proven methods. This class teaches the effects of rear oxygen sensors on fuel trim. How to properly test for exhaust leaks causing skewed readings. During the path from oxygen sensors to wideband we are going to learn how to utilize scan and scope data to dial in a proper diagnostic routine. Technicians are always asking for air fuel sensor help. This class will lay a foundation in oxygen sensor and AF sensor theory and operation. Using data to determine air fuel functionality. How to diagnose air fuel sensors with oxygen sensor data and vice versa, exhaust leaks and their effect on data. We will also demonstrate solid methods with different tools to verify exhaust system integrity.
