Sitting at a red light is probably not the best way to check codes. I would go back and run the self test properly. The self test assumes the truck is not running, so since you were sitting at a light, (I assume idling), the system since a fault. Rerun the tests and see if you still get the code. Clear it out and see if it comes back. If the truck is running fine, keep on trucking.
