P1441 Scion Code - Secondary Air Injection System Switching Valve No.2 Stuck Open Bank 1
Quick Answer
The Engine Control Module (ECM) detects pressure change with the pressure sensor to determine malfunctioning parts in the system,and stores the DTCs. Common causes include Faulty Vacuum Switching Valve (VSV), VSV for air injection control circuit Bank 1, Air switching valve No.2 Bank 1. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1441 Scion Description
Points A and B:
ECM detects pressure changes (decrease), and determines that the ASV No.2 is open.
Points C and F:
ECM detects pressure and exhaust pulsation, and determines the pressure pattern of the system.
Point D:
ECM operate the system, as indicated by the dashed lines, to determine which of the ASV No.2 is malfunctioning only when pressure changes cannot be detected at point B.
Point E:
ECM detects exhaust pulsation to determine the condition of the system.
