Carburetor - Idle-up Control (Cont'd) / Fuel Cut Solenoid Valve (Models without catalyzer)

EF & EC-172prose procedure

Applies to models without catalyzer.

Idle-up Control (Models without catalyzer) (Cont'd)

This system prevents poor battery charging and erratic idling when the following load switches are operating: Headlamps; Rear defogger; Blower motor; Power steering switch. In this system, the proper fuel is added when solenoid valve attached to carburetor is in the "ON" position.

INSPECTION

Idle-up control solenoid valve

1
Connect solenoid valve connector to battery.

3
If no sound is heard from solenoid valve, replace with a new one. 1) Disconnect harness from harness connector. 2) Remove solenoid valve from carburetor. 3) Install new solenoid valve. After replacement, check that solenoid valve is in good condition.
