My 2006 Tundra SR5 TRD 4X4 showed a trouble code of p2445. secondary air pump stuck off. I did some poking around on here and other forums and found this is a problem with lots of Tundras first AND second Gen. And it is expensive to fix. There are gizmos you can buy that bypass this set up. However,after talking with Toyota and my local car guru,we unhooked the vacuum lines from the two switches on the passenger side of the intake and I plugged the lines goin to the intake. after driving the truck twice,codes reset and truck runs fine.Here is a pic of the switches and plugged vacuum lines. Before shellin out huge money and or goin crazy trying to trouble shoot the pumps,try this. Hope it helps ya.

UPDATE: Truck ran great the day I did this. the next morning,no codes & ran great,after about a half hour drive the flipping code came back & it went in to limp mode,gggrrr...guess I will have to send Paul some money & get a module.
