CEL code
The CEL came on yesterday, went to AutoZone today to get thescanner put on forthe code. It pulls up P0491 "Secondary Air Flow (bank 1)". AutoZone could not find this code in the data system. Looked it up inmy service manual, it does not list this code. Does anybody no about this code or some info on it? BTW I have a 2003 allroad 2.7T auto with 69000 miles with no mods.
Thanks
