P2443 Code - Secondary Air Injection System Switching Valve Stuck Closed Bank 2
Quick Answer
To accelerate the activation of catalyst when warming up the engine, the air injection system pumps the secondary air to the exhaust manifold by pressure. Common causes include Faulty Vacuum Switching Valve (VSV), Vacuum Switching Valve (VSV) harness is open or shorted, Vacuum Switching Valve (VSV) circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
