Code P2258 Ford Description

The P2258 Ford diagnostic trouble code indicates a problem with the Secondary Air Injection System Control 'A' Circuit being too high. This system is designed to reduce harmful emissions by injecting fresh air into the exhaust system to help with the combustion process. When this code is triggered, it means that there is a high voltage condition in the circuit that controls the secondary air injection system. This can lead to inefficient combustion, increased emissions, and potential damage to other components in the vehicle.

  • When getting this code I have been trying to figure out is that means that the secondary air injection pump needs to be replaced or if I have a short somewhere in the wiring. I just bought this car and I cant change the title over until I get it through the emissions test. YIKES. I thought it would be a simple thing.
