Code P2444 Subaru Description

The P2444 Subaru code refers to a problem with the Secondary Air Injection System Pump being stuck on Bank 1. The Secondary Air Injection System is responsible for introducing fresh air into the exhaust system to help reduce emissions. When the pump is stuck on, it means that it is continuously pumping air into the exhaust system, even when it is not needed. This can lead to an imbalance in the air-fuel mixture, affecting the vehicle's performance and emissions.
