Replacing the Secondary Air Injection Valves for codes P2440, P2441, P2442, P2443, 4.7L on Toyota.

I am replacing a Toyota Sequoia SUV's secondary air injection check valves. This was for a code P1442 Air injection system switching valve stick closed but this is the same if stuck open also. Tip, you do not have to remove the water crossover. You can also access the starter if you need to change that. Tundra 4.7l
