Hey everyone..I'm trying to get some questions answered about some codes my '08 Fusion is throwing. They have been on for a few weeks now. I cleared the codes and they came back the next day. The two codes are P0410 and P0491. Both are related to secondary air injection. I have an appointment for my car to be fixed at the Ford dealership on Saturday morning. I called them and was asking some questions about how long it would take or if I would need a rental car. I only got attitude on the phone and they didn't really seem to understand the codes I had pulled. I am just wondering if anyone knows if there are things I can check before taking it to the dealership and dishing out the money (and possibly having to rent a car on top of that)? I have quickly looked over the car and there are no damaged hoses or anything. I have read that humidity can cause these codes and some people said it was the MAF so I will make sure to take mine out and clean it (once this rain in NJ stops!) Just looking for some advice on what the more simple fixes could be before I take it in to the shop. I need to get this taken care of soon though because I'm due for inspection in June. Thanks for your help!
