EFI-436 - Rear O2 compensation
The ECM monitors the compensation being made by the rear sensor and sets this code when excessive compensation is being called for. Note: the front sensor can cause this code to be set in the rear.
Usually when I see a code for the rear O2 sensor, it's the front one acting up or elicting a slow response, so the rear one doesn't know what to expect. Might be better to replace them both.

A learning experience is one of those things that says, "You know that thing you just did? Don't do that."
