Okay. First and foremost, I am a new member on this site/forum and I have been dealing with these codes for about 2 weeks. Not sure if it is my secondary air flow sensor or air pump? I DID find a blown 40amp fuse in the fuse box. I installed the new fuse and it has blown again. I'm trying to diagnose this problem and in need of some assistance. I joined this forum for your guidance to solve this problem and praying that the SERVICE ENGINE light will go out. How do I test the air pump to see if its still in running order? Connectors seem too look good and no frays in the wiring from any connectors.
