Air Management Solenoid

Faults in air management solenoids or circuits should set a service code. See QUICK TEST in TESTS W/CODES - EEC-IV article in the ENGINE PERFORMANCE section. If service code has not been set, disconnect solenoid harness connectors. Measure resistance across terminals. Resistance should be 50-100 ohms. If resistance is not as specified, replace solenoid. If resistance is as specified, see CIRCUIT TEST KC in TESTS W/CODES - EEC-IV article in the ENGINE PERFORMANCE section for additional circuit testing.
