Maybe the light was on so long the bulb burnt out...
Another and more likely possibilty is that the computer stored it as a memory code/hard code and decided to turn off the light....

you might also want to check for exhaust leaks on that side before the 02 sensor. That could cause it to throw a lean code too. Hope this helps!
