Hello! I have 2011 Toyota Tundra v8 4.6l with 90,000 miles about 3yrs ago I changed out the secondary air injector valves on both sides and never had a problem, Code p2441 by the way. But now about two weeks ago a new problem showed up and it’s a code p2432 and p2440 I check and it says it the valves stuck open Or closed, but I have checked on cold mornings and the air injectors work and the open and close valves are closing like they should! But I don’t know where to go to get a computer like yours
A custom upgrade is to remove the circles that open and close.

In fact, your truck would run better, cost less, and be more reliable if it didn’t have this system
The secondary air injection system is not working correctly. Either the pump isn't working or the VSV is shot or something else. See the attached for a bypass kit -
Take it to one of the large auto supply stores for a free scan for DTCs with a fairly sophisticated tool.
