P1130
DTC P1130 SWIRL CONTROL VALVE CONTROL SOLENOID VALVE
Description
If DTC P1130 is displayed with P1165, first perform trouble diagnosis for DTC P1165. See: 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 valves shut/open condition. This solenoid valve is operated by the ECM.
When engine coolant temperature is below 10 °C (50 °F) and above 55 °C (131 °F), swirl control valve is kept open regardless of condition.

COMPONENT DESCRIPTION
Swirl Control Valve Control Solenoid Valve
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.

On Board Diagnosis Logic
DTC Confirmation Procedure
Perform "Procedure for malfunction A" first. If the 1st trip DTC cannot be confirmed, perform "Procedure for malfunction B". If the 1st trip DTC is not
confirmed on "Procedure for malfunction B", perform "Procedure for malfunction C".
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.
PROCEDURE FOR MALFUNCTION A
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" .
PROCEDURE FOR MALFUNCTION B
TESTING CONDITION:
- For best results, perform the test at a temperature above 5 °C (41 °F).
- Before performing the following procedure, confirm that battery voltage is more than 10 V at idle, then stop engine immediately.
With CONSULT-II
1. Turn ignition switch "OFF" and wait at least 10 seconds.
2. Turn ignition switch "ON".
3. Check "COOLAN TEMP/S" in "DATA MONITOR" mode with CONSULT-II.
4. Confirm COOLAN TEMP/S value is 40 °C (104 °F) or less.
If the value is more than 40 °C (104 °F), park the vehicle in a cool place and retry from step 1.
5. Start engine and wait until COOLAN TEMP/S value increases to more than 55 °C (131 °F).
If 1st trip DTC is detected, go to "Diagnostic Procedure" below.
With GST
Follow the procedure "With CONSULT-II" .
PROCEDURE FOR MALFUNCTION C
TESTING CONDITION:
- For best results, perform the test at a temperature above 5 °C (41 °F).
- Before performing the following procedure, confirm that battery voltage is more than 10 V at idle.
With CONSULT-II
1. Start engine and warm it up to normal operating temperature.
2. Turn ignition switch "OFF" and wait at least 10 seconds.
3. Turn ignition switch "ON" again and select "DATA MONITOR" mode with CONSULT-II.
4. Start engine and let it idle for at least 20 seconds. If 1st trip DTC is detected, go to "Diagnostic Procedure" below.
