DTC P1132 SWIRL CONTROL VALVE
Component Description
Swirl control valve consists of actuator and valve. The valve is installed in the intake manifold, and the actuator is connected to the rear end of the valve shaft.
The swirl control valve uses a step motor which has four winding phases. It operates according to the output pulse signal of the ECM. Two windings are turned ON and OFF in sequence. Each time an ON pulse is issued, the valve opens or closes. When no change in the control position is needed, the ECM does not issue the pulse signal. A certain voltage signal is issued so that the valve remains at that particular opening.
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.
Possible Cause
- Harness or connectors
(The swirl control valve circuit is open or shorted.)
- Swirl control 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" and wait at least 2 seconds.
2. Select "DATA MONITOR" mode with CONSULT-II.
3. Start engine and let it idle for at least 10 seconds.
4. Turn ignition switch "OFF" and wait at least 10 seconds.
5. Turn ignition switch "ON" and wait at least 2 seconds.
6. Start engine and let it idle for at least 10 seconds.
7. Maintain engine speed at about 2,000 rpm for at least 10 seconds.
8. Turn ignition switch "OFF", wait at least 10 seconds and then turn "ON".
If 1st trip DTC is detected, go to "Diagnostic Procedure" below.
If 1st trip DTC is not detected, go to next step.
9. Perform step 5 through 8 three times.
WITH GST
Follow the procedure "With CONSULT-II" above.
