Idle Speed/Throttle Actuator - Electronic: Description and Operation
DescriptionThe idle speed actuator is of the double coil type and has two coils. the two coils are driven by separate driver stages in the engine control module. Some cone coils receive the inverse signal of the other. Depending on the pulse duty factor the equilibrium of the magnetic forces of the two coils will result in different angles of the motor. In parallel to the throttle valve a bypass hose line is arranged, where the idle speed actuator is inserted in.
