Just replaced the distributor last week and the car has been running good. Today the Rear O2 sensor code came up on my check engine light. Is there any relationship to the distributor being replaced?
I know the mechanics adjusted the timing. Does this sensor tyoically go bad or is it likely a bad contact or dirty?
Car is still running good.

The rear O2 is mainly for emissions because it monitors the catalyst efficiency.
