Ride it a couple days, don't lug it. It could clear itself.
If a light illuminates then the ECU triggers a code that displays at the time on the tach. If there's a code jot it down and check the service manual. If there's not a code it'll be surprising, but I understand there's a couple sensors that don't trigger a code, just the light, and the service manual mentions them someplace but I don't know where. I just checked troubleshooting and they are not covered there.
