Inside the tutorial the reader can get explanation related to element, sensor, diagnostic, post cat sensor, heating, fuel mixture, o2, and malfunction. Lots of things regarding connector, operating temperature, heating element, sensors, heater, exhaust gases, and cold start are presented in the tutorial.
The tutorial presents discussion regarding failure, sensor heater, cylinder engines, electric heating, temperature, electric heating element, and pre cat sensor. The following are chosen from this tutorial:
This article explains how oxygen sensor heaters work, how failures are detected, and how to correctly identify the sensor in need of replacement. Why Do Oxygen Sensors Have Heaters? An oxygen sensor needs to be at a temperature of around 600 degrees Fahrenheit in order to function, so immediately after a cold start it cannot provide any useful information for controlling the fuel mixture.
Additionally, the tutorial contains discussion around oxygen sensor heater, engine, ecu, oxygen, oxygen sensor, codes, and electrical malfunction.
