Air Injection Vacuum Control Solenoid Valve: Testing and Inspection

Dual Thermactor Air Control Solenoid Valve:

Functional Check

1. Determine the function of each valve by externally energizing with vacuum pump and output gauge.
2. Check the resistance of each solenoid at the coil terminals, the resistance should be between 51 and 108 ohms.
3. If resistance is not within these values, the solenoid should be replaced.
