EGR Solenoid
- Disconnect EGR solenoid electrical connector. Check resistance between EGR solenoid terminals. Resistance should be 29-35 ohms (Eclipse & Galant), or 36-44 ohms (Diamante, Mirage, Montero & Montero Sport), at 68°F (20°C).
- 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.
