I have a 2001 S10 that is given me codes P1416, P0415, P0410. I got a book from the auto store but did not have those codes in it. I then got a code reader and found out P1416 - Air System Bank 2, P0410 - Secondary Air Injection System Malfunction, P0415 - Secondary Air Injection System Switching Valve B Circuit Malfunction. The book from the store does not have any of this in it. If I take it in they said it will take everal days to run thru all the steps to find the problem and alot of money. If any one can give me step by step to find this problem and fix it?
