Secondary Air Injection Malfunction error
 
Ok, I have the check engine light on....I know what the code is P0410. From what I looked up, oxygen is pumped into the exhaust when our cars first crank up to help warm up the cats. When the hose is cracked or needs to be replaced it makes the car throw this particular code.

Its strange how this came on 2 days after I had my air pump replaced at the stealer. This was about 4 months ago so I'm not going back to complain. My question is does anyone have a picture of where this hose is? I hear it is a $12 part, and I don't want to go back to get a diagnostic fee when I already know the problem. Can anyone point me in the right direction? Thanks

I replaced the hose, and light went out. So I guess I'm ok.

Thanks

I'll try to get one for u this weekend. I had my Indy take care of it while I was at work. I was so damn happy the light was off I didn't ask any questions. He charged me like $20 bucks.
