Code P1441 Scion Description

The P1441 Scion code indicates a problem with the Secondary Air Injection System Switching Valve No.2 being stuck open in Bank 1. The secondary air injection system is responsible for reducing harmful emissions by introducing fresh air into the exhaust system during cold engine starts. This helps to heat up the catalytic converter quickly and improve its efficiency in reducing pollutants.
