The computer uses the readings from the narrow band oxygen sensor before the catalytic converter and the secondary sensor to determine if the cat is working properly. The heater element is an internal resistor that heats up as Universal sensors can be made to fit a variety of applications providing that the sensor is the correct type for the vehicle in question. The Oxygen sensors can usually be found screwed into the exhaust system.
Three and four wire heated oxygen sensors evolved in order to reach operational temperature more rapidly.

Today we discuss the design and function of these sensors, and some of the pitfalls encountered during the diagnosis of their related fault codes. An exhaust gas oxygen sensor (EGO) is very useful for setting up the MegaSquirt® EFI controller volumetric efficiency table, and while it is highly recommended, it is. They are located closer to the engine than to the tailpipe.
