Mixture Control Solenoid: Testing and Inspection

Fig. 9 Solenoid valve terminal identification:

1. Place ignition switch in Off position, then disconnect solenoid valve connector.
2. Using suitable ohmmeter, check resistance between terminals as shown in Fig. 9.
3. Resistance should be approximately 50 ohms for all except bowl vent solenoid valve, which should be approximately 80 ohms.
4. If resistance values are not as specified, replace affected solenoid(s).
