Oxygen Sensor: Description and Operation
Operation

The upstream heated oxygen sensor is located at the catalytic converter inlet and detects the concentration of oxygen in the raw exhaust gases; an internal
heater reduces the warm up time of the sensor output.

An oxygen sensor (without heater) is located at the converter outlet.

The ECM receives input signals from the sensors & varies the fuel injector duration (mixture) to provide optimum gas emissions.
