I thought I explained it on the first answer that I gave. The air pump must work in order for the code to go away even though it may be an O2 sensor that is bad. The relay will either bein the underhood fuse box which will be marked on inside of cover or in line with secondary air pump. This has to be checked with scanner and it will cause convertr to go bad and end up costing major bucks. Pic is included of secondary air pump. Its on the frame of the truck along with the solenoid. But it may not be this that is bad it may b the other thing I sent earlier.
