Code P1445 Toyota Description
The P1445 diagnostic trouble code for Toyota vehicles indicates a problem with the Secondary Air Injection System Switching Valve being stuck closed in Bank 2. The Secondary Air Injection System is responsible for reducing harmful emissions by injecting fresh air into the exhaust system during cold starts, allowing for more efficient combustion. When the switching valve is stuck closed, it can disrupt this process, leading to increased emissions and potential engine performance issues. This can trigger the check engine light and negatively impact the vehicle's overall efficiency.
