P1131
COMPONENT DESCRIPTION
The swirl control valve control solenoid valve responds to signals from the PCM. When the PCM 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 PCM sends an OFF signal, the vacuum signal is cut and the swirl control valve opens.
CONSULT-II Reference Value in Data Monitor Mode
Specification data are reference values.
ON BOARD DIAGNOSIS LOGIC
Malfunction is detected when an improper voltage signal is sent to PCM 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
DTC Confirmation Procedure
NOTE: If "DTC Confirmation Procedure" has been previously conducted, always turn ignition switch "OFF" and wait at least 10 seconds before conducting the next test.
With CONSULT-II
1. Turn ignition switch "ON".
2. Select "DATA MONITOR" mode with CONSULT-II.
3. Wait at least 5 seconds.
If 1st trip DTC is detected, go to "Diagnostic Procedure" below.
With GST
Follow the procedure "With CONSULT-II" above.
