I am returning these 2 codeson my 02 S60 (non-turbo)

P2101 Throttle Actuator Control Motor Circuit Range/Performance
P2173 Throttle Actuator Control System - High Airflow Detected

The codes popped up on an extremely cold day -15F 30-40 below windchill factor. I've erased them and restarted and they have not popped up again. Could this be a fault caused by the extreme cold, or is there definitly an issue here,

Thanks!

 

Sounds like they would transfer over to throttle body codes which should still be under the 10 year 200,000 mile Warranty.
