DESCRIPTION
The throttle opener system is used on air conditioned, carbureted models and consists of a throttle opener assembly, solenoid valve, engine speed sensor and air conditioning compressor switch. Engine speed sensor is also used in air switching valve system.
When this sensor detects engine speed at or below specified value, air switching system does not operate. When engine speed is above specified value, air switching system works as designed.
COMPRESSOR SWITCH "ON"
When engine speed sensor detects engine speed at or below specified value, solenoid valve is opened so as to transfer intake manifold vacuum to throttle opener. Throttle valve is slightly opened by throttle opener and opener lever which is freely movable on throttle valve shaft. Engine will then run at a speed resulting from setting of new throttle valve opening against compressor's load.
COMPRESSOR SWITCH "OFF"
Throttle opener system stops working and engine runs at original idling speed.
THROTTLE OPENER OPERATING SPEED
- Turn lights and accessories off. Place transmission in Neutral. Run engine until normal operating temperature is reached. On 1.4L and 1.6L engines, electric fan must be off. Make sure that curb idle is within specifications.
- If necessary reset idle speed to specifications. Switch A/C switch to "ON" position. Adjust the engine to specified speed with throttle opener screw. Turn the A/C on and off several times to check for throttle lever operation. (Схема №1)
