Question about book content

Greetings friends, I have a question about the content of the book, on the topic of oxygen sensors, I would like to know if they teach how to diagnose 4 and 5 wire Air Fuel Ratio Sensor.

Thank you

Hey marvinmeca! Unfortunately, there's no content in the book that specifically covers wideband or air/fuel ratio sensors. Fortunately, there's other principles (bias voltage, current flow) in the same book that'll come in handy when diagnosing these sensors.

We've got a sticky going covering air/fuel ratio sensors, if you're interested:

Also, check out NGK Technical Training
