Rear O2 sensor fault frequently in RSTuner DTC memory?

[len_beach]

I've been fiddling with my RSTuner alot recently and it often brings up a rear O2 sensor fault in the memory.

This doesn't show as a current fault but only historic.

Any thoughts?

Anyone?

Won't cause you any problems, change it if it bothers you?

Thanks Scott. Is this likely to bring the service light on or just stay in the memory?

I can't tell at the moment as the service light is on due to a dodgy ABS sensor.

I have disconnected it on both my clios and ever seen a warning light, some people do but I never have.
