Code P2448 2007 Ford Fusion Description

The P2448 code on a 2007 Ford Fusion indicates a problem with the Secondary Air Injection System, specifically high air flow in Bank 1. The Secondary Air Injection System is designed to reduce harmful emissions by injecting fresh air into the exhaust system, which helps burn any remaining fuel before it exits the tailpipe. When the system detects high airflow in Bank 1, it means that there is an issue with the amount of air being injected, which can lead to inefficient combustion and increased emissions.
