P1131




Component Description
The swirl control valve control solenoid valve responds to signals from the ECM. When the ECM sends an ON (ground) signal, the solenoid valve is bypassed to apply intake manifold vacuum to the swirl control valve actuator. This operation closes the swirl control valve. When the ECM sends an OFF signal, the vacuum signal is cut and the swirl control valve opens.

Consult-II Reference Value In Data Monitor Mode:






On Board Diagnosis Logic
Malfunction is detected when an improper voltage signal is sent to ECM through swirl control valve control solenoid valve.

Possible Cause
- Harness or connectors
(The swirl control valve control solenoid valve circuit is open or shorted.)
- Swirl control valve control solenoid valve
