By the way, I changed the exhaust sensor when I saw the code P0365 camshaft position sensor bank 1 circuit malfunction, and you said I changed O2 sensor. Did I misgiving information or they are the same. I have no ideas where to look for O2 sensors until now you tell me where to look for cat O2 sensors.

I'm not I get what your saying exactly. So you have changed the O2 sensors in the cats right? If not its pretty easy and just follow what I said above. If you have more trouble on with the cat O2 sensor I can take a picture to help you. Also did you change the camshaft position sensor?
Now assuming that your O2 sensors are good, and your ICV is clean, it is likely due to the vacuum hose somewhere. I'm sorry I'm not exactly sure where the secondary air pump is to the ICV on the 3.0 is, but the main one to the exhaust manifold is working fine since you have no idling issues. Try to look for a smaller black 0.5" diameter hose attaching to ICV. It is possible that it somehow got discconnected and never reconnected causing the SES light to show up. I'm not familiar with the 3.0i engine so feel around the ICV for a hose outlet.
