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.
