What is an oxygen sensor?
The oxygen sensor, or O2 sensor, is a device mounted in the exhaust pipe to constantly monitor the oxygen content in the exhaust gases that exit the engine. The information from the O2 sensor is used by the engine's electronic control unit (ECU) to help determine how much fuel is needed to mix with the air coming into the engine so that the engine may run efficiently. O2 sensors are located ahead of and behind the catalytic converter. A vehicle may have two to five O2 sensors or more.
