Downstream O2 Sensor - Right Side

The downstream heated oxygen sensors thread into the outlet pipe at the rear of the catalytic convertors. The downstream heated oxygen sensor
input is used to detect catalytic convertor deterioration. As the convertor deteriorates, the input from the downstream sensor begins to match the
upstream sensor input except for a slight time delay By comparing the downstream heated oxygen sensor input to the input from the upstream
sensor, the PCM calculates catalytic convertor efficiency.
