Secondary Air Injection System Switching Valve Stuck Open Toyota Tundra

One of the lines on top of the air pump runs to the other side of the engine towards the firewall. P2440 is a diagnostic trouble code (dtc) for secondary air injection system switching valve stuck open bank 1. Its just junk from the exhaust from the engine.

I took it to the vehicle maintenance shop on base and they read off 2 codes to me, p2440 & p2442, which is secondary air injection switching valve stuck bank 1 and 2. But toyota has problems with the air injection pump coming apart and causing debris in the system holding the valve open.
