The Trainer

Join Motor Age in this episode of “The Trainer” with Technical Editor Brandon Steckler as he demonstrates how to use the Autel MS919 scan tool to not only identify an intermittent misfire but also determine what the cause of the misfire is. 

In this video, Brandon describes the combustion process of a spark ignition internal combustion engine. He explains how an intermittent misfire affects the exhaust gas and how one appears in the eyes of a heated oxygen sensor and/or a wide-band air-fuel ratio sensor.   

Through the monitoring of a few basic OBDII global PIDs, Brandon quickly and easily determines the cause of the misfire. The analysis can be conducted right from the driver’s seat without ever opening the hood and can easily point to an ignition fault or an injector fault. It’s all about “chemistry” of the catalytic converter. 

Tune in and find out how the Autel MS919 can use this technique to take your diagnostics to the next level.
