P2440 TOYOTA lawmaking description
To advance the activation of catalyst when warming upwards the engine, the air injection system pumps the secondary air to the exhaust manifold past pressure. The secondary air is supplied by the air pump and it is pumped to the exhaust manifold through the air switching valve. Open up and close movement of the air switching valve is regulated by the Vacuum Switching Valve (VSV).The air pump and the air switching valve are observed by the Engine Control Module (ECM) and are used to detect malfunction in this organisation. The ECM monitors the secondary air injection system and detects malfunction using a pressure sensor located on the air switching valve.
The ECM observes the pressure in the secondary air passage using the pressure level sensor located on the air switching valve in the secondary air injection system. The sensor detects an exhaust pressure in the secondary air passage.
