All Models (Ported EGR Valve)

WARNING: This page does not describe the selected car, but rather 196 other vehicles, including the 2022 Subaru Outback, 2022 Subaru Legacy, 2022 Subaru Impreza, 2022 Subaru Forester, and 2022 Subaru Crosstrek. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect vacuum hose from EGR valve. Warm engine to normal operating temperature. Connect a hand-held vacuum pump to EGR valve. With engine idling, apply 8 in. Hg to EGR valve. If vacuum holds and idle becomes unstable or engine stalls, EGR valve is functioning properly. Reconnect vacuum hose. Increase engine speed to 3000-3500 RPM. Ensure EGR valve opens.
