The O2 sensor referred to in the context of the thread is the rear one.
Its function is to monitor the state of the cat converter's efficiency.
While there is some literature that some of the newer car models
in the D-C line-up have linked the rear O2 sensor output with the front O2
sensor output, I have not personally come across anything that suggests
that the D-C trucks do this.
