Code P2258 2007 Ford Fusion Description

The P2258 diagnostic trouble code (DTC) for a 2007 Ford Fusion indicates a problem with the Secondary Air Injection System Control 'A' Circuit being too high. The secondary air injection system is responsible for reducing emissions by introducing fresh air into the exhaust system to help burn any remaining fuel before it exits the tailpipe. The 'A' circuit refers to a specific part of the system that controls the flow of air. When the circuit is reading as high, it means that there is an issue with the electrical signals being sent to the system, causing it to operate outside of the normal parameters.
