Keep your secondary air injection system flowing the right way with the Standard Ignition Secondary Air Injection Pump Check Valve, MPN AV70. This one-way check valve installs as a direct-fit replacement for the 2008-2011 and 2013-2021 Lexus LX570, the 2008-2011 and 2013-2021 Toyota Land Cruiser, the 2008-2022 Toyota Sequoia, and the 2007-2021 Toyota Tundra.
One-way flow control: Allows fresh air from the secondary air injection pump to pass into the exhaust stream while blocking flow in the reverse direction.
Protects the air pump: Designed to keep hot exhaust gases and moisture from traveling back toward the air injection pump.
Secondary air injection role: Supports the cold-start air injection process that helps the catalytic converter reach operating temperature.
Direct-fit replacement: Made to install on the listed applications.
Signs this valve may need replacing include a stored secondary-air-system code or evidence of exhaust backflow reaching the air pump. Because those symptoms can have other causes, diagnose the system before replacing. If a failed check valve is the cause, installing AV70 restores correct one-way air flow.
Interchange: Manufacturer part number AV70.
