Mixture Control Solenoid: Testing and Inspection

FBSV And SCSV Locations:

To test the Feedback Solenoid Valve, located in the float bowl of the carburetor, proceed as follows.

Connector M21:

1. Disconnect the wiring harness connector (connector M-21).
2. Test for resistance between terminals 1 and 3.

Resistance: 38-44 ohm @ 20°C (68°F)

3. If the solenoid valve's resistance is out of the standard value limits replace the solenoid.

For diagnosis and testing of the feedback carburetor system or the control of the feedback solenoid valve, refer to COMPUTERIZED ENGINE CONTROLS.
