A/C Idle Boost Throttle Controller: Description and Operation
A/T Idle Control Solenoid Valve
When the air conditioner is turned on, the A/C idle control solenoid valve opens. This causes the A/C idle control diaphragm to open the throttle
valve, which in turn raises the idle speed. This valve also opens when coolant temperature is low to ensure stable idling regardless of position of A/C
switch.
