The P2440 code for a 2005 Toyota 4Runner indicates a problem with the Secondary Air Injection System, specifically related to the Air Switching Valve. This can be caused by a malfunctioning valve, a blockage in the air passages, or an issue with the control circuit. It's advisable to inspect the air injection system components for damage or debris and to check the electrical connections for continuity. Addressing this issue is important for maintaining emissions compliance and optimal engine performance.
