OBDII code P0412

[5111]

I have a 2001 Bullitt Mustang GT that is supercharged.

My check engine light came on so I took it down to Autozone to have them run the codes. It came back with code P0412. When I referenced it on http://www.bullittarchive.com it said:
P0412 - Secondary Air Injection (AIR) system upstream flow----See DTC P1411

So I look up P1411 and it says:
P1411 - Secondary Air Injection (AIR)system downstream flow

The secondary air injection system does not detect the presence of air in the exhaust when introduced by the secondary air injection system

*Electric AIR Pump
*Hose from AIR pump leak
*AIR bypass solenoid leak/blocked
*Hose from AIR pump blocked
*AIR bypass solenoid stuck open/closed

In order to test the AIR pump, it must be capable of driving the HO2S lean.

I can't find any vacuum leaks, so what should I check now?

have someone shut the rear o2's off and see if it comes back after erasing all codes in memory

I am running MILs and am pretty sure that my tuner already turned them off.

stupid question, but i dont think the SOHC 4.6 motors have AIR. i thought only the older 4v motors had them. reason i say this is because i did a training smog on my car and there isnt AIR injection on my 98gt.
