October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.
Modules, Relays & Solenoids: Solenoids: Notes
- Secondary Air Injection By-Pass/Diverter (AIRB/AIRD) Solenoids
Faults in secondary air injection solenoids or circuits should set a diagnostic trouble code. See QUICK TEST in TESTS W/CODES - EEC-IV (5.0L)
article in the ENGINE PERFORMANCE section. If diagnostic trouble code has not been set, disconnect solenoid to be tested.
- Measure resistance between sensor terminals. If resistance is not 50-100 ohms, replace solenoid. If resistance is 50-100 ohms, solenoid is okay. See CIRCUIT TEST KC in the appropriate TESTS W/CODES - EEC-IV (5.0L)
article in the ENGINE PERFORMANCE section for additional circuit testing.
