Servo Diaphragm

The servo diaphragm opens throttle valve by applying negative pressure from 3-way solenoid valve, during A/C and power steering operation.

Servo is also activated during power steering operation when pressures rise to a predetermined level.

On models with M/T, servo operates when engine speed is 900 RPM. On models with A/T, servo operates when engine speed is 1150 RPM.
