EGR Solenoid

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.
