Webinar from ASE: Exhausted! Oxygen and Air Fuel Sensor Diagnostics

Feb. 24, 2026

The National Institute for Automotive Service Excellence (ASE) is hosting a free webinar on Tuesday, February 24 at 4 p.m. ET entitled "Exhausted! Oxygen and Air Fuel Sensor Diagnostics."

In this webinar, Andrew Fischer with WORLDPAC will lay a foundation for oxygen sensor and air fuel sensor theory and operation using data to determine air fuel functionality. Fischer will discuss how to diagnose air fuel sensors with oxygen sensor data and vice versa, exhaust leaks, and their effect on data. Fischer will also demonstrate solid methods to verify exhaust system integrity with a variety of tools. 

Participants will receive a certificate of attendance for the live session. Those who are not sure if they can attend are encouraged to still register as they will receive a follow-up email with details on how to attend a recorded session, if available.
