If you are unable to get the exhausts up to temperature (lots of puddles and town traffic) then the sensor can cry foul as the cats are not working due to low temp.

Mr Tony has previously advised on the Italian Tune Up method and it does seem to work on mine.

If the engine light comes on and you get that code - check in case it is another more dangerous one - then give it an italian tune up - big heavy right foot session.

Switch off and leave it for a bit. re-start and drive it hard to get exhaust temperature hot. Switch off and leave it. should have cleared on next restart, if not run hard and stop-leave-start one more time.

Observe when you get the light and see if it is following heavy rain/spray, slow driving which would let it cool.
