Variable Induction Control Solenoid: Description and Operation
SWIRL CONTROL VALVE CONTROL SOLENOID VALVE
Description
If DTC P1130 is displayed with P1165 first perform trouble diagnosis for DTC P1165.
SYSTEM DESCRIPTION
This system has a swirl control valve in the intake passage of each cylinder.
While idling and during low engine speed operation the swirl control valve closes. Thus the velocity of the air in the intake passage increases promoting
the vaporization of the fuel and producing a swirl in the combustion chamber.
Because of this operation this system tends to increase the burning speed of the gas mixture improve fuel consumption and increase the stability in
running conditions.
Also except when idling and during low engine speed operation this system opens the swirl control valve. In this condition this system tends to increase
power by improving intake efficiency via reduction of intake flow resistance intake flow.
The solenoid valve controls swirl control valve's shut/open condition. This solenoid valve is operated by the ECM.
