Code P1131 Nissan Description
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 Engine Control Module (ECM).
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.

- Faulty Swirl control valve control solenoid valve
- Swirl control valve control solenoid valve circuit is open or shorted

Impossible to locate this part in my car ! Can you please help me find it ?
-
2008 Pathfinder V-6, LE. I have code P1131. But can’t locate this solenoid valve.
-
Please double check the code number. There is no P1131 code listed in the factory service manual for your model year. Also, there is no Swirl Control Valve in your vehicle.
-
I’m so sorry. It’s code C 1131. Engine signal 2. I have no idea what that could be. :-(
-
Do you have any other codes? most of the times the C1131 code is combine with another code. The C1131 code means that the Anti-lock Brake System (ABS) control module judges that there is an engine malfunction, based on the the Engine Control Module (ECM) signal.
If there are no other codes or symptoms, try just clearing the code.

Only P2119, throttle body actuator... now along with C1131.
I cleaned throttle body with new gasket. Replaced all 4 cats and O2 sensors, 6 ignition coils and spark plugs, and canister purge valve. Everything was fine for 20 miles. Then I get C1131. Could it be the battery? I had to recharge it because it was not run while I replaced all the above. Thanks for your help -
Could it be the battery?
It's possible. I would just clear the code for now, otherwise you may still have a problem with the Throttle Body and may need to replace it. -
Thank you so much. I will get a new battery and clear the code. Throttle response etc is excellent. Maybe throttle needs recalibrating.
