Details of the Toyota p2443 OBD Code
Code P2443 in Toyota indicates a problem with the secondary air injection system pressure sensor circuit.
Code P2443 for Toyota means that there is a problem with the Secondary Air Injection System Switching Valve Stuck Closed Bank 2. This code is triggered by the Engine Control Module (ECM) when it detects that the switching valve for the secondary air injection system on bank 2 is stuck closed.
The secondary air injection system helps reduce emissions during cold engine startup by injecting fresh air into the exhaust system.
When the switching valve is stuck closed, it can affect the proper operation of this system, leading to increased emissions.
