It might be the 2nd O2 sensor ... the one that monitors the cat operation.
If it send a constant and high enough voltage output to indicate an
extremely rich and heated condition in the cat, it can trigger the check
engine light.
It happened a couple of times with me last winter on extremely cold days
while waiting for someone ... so cold that I had to run the heater for
about 5 min. every 45 minutes to keep the feet from freezing. I reset
the computer and the light went off.
