EGR Solenoid

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2003 Mitsubishi Outlander, 2003 Mitsubishi Montero Sport, 2003 Mitsubishi Montero, 2003 Mitsubishi Lancer, and 2003 Mitsubishi Galant. However, it is still accessible from the selected car via links, so may be relevant.

Disconnect EGR solenoid electrical connector. Check resistance between EGR solenoid terminals. See EGR SOLENOID RESISTANCE table. If resistance is not as specified, replace EGR solenoid. If resistance is as specified, go to next step.
Label and disconnect vacuum hoses from EGR solenoid. Connect hand vacuum pump to EGR solenoid port "A". See Fig 1. Apply vacuum. Vacuum should leak. Using battery voltage and ground, energize EGR solenoid. Apply vacuum. Vacuum should hold.
