SOURCE: service engine soon light

Thisi s a problem my daughter had on her 2003 nissan and it was under a voluntary recall so if you bring it to dealer and tell them they have to replace swirl Valve free. It regulates the fuel. I have a 2005 nissan that had other engine codes and I have asked them to check swirl valve but I am getting run around from my dealer. Get it done at dealer asap or it can cause other problems with fuel system.

SOURCE: Pls where is Swirl Control Solenoid Valve located in Infiniti QX4

This link shows the location of the SCV, If your motor is different the location should be similiar.

There's a vaccuum line that runs off the SCV to the SCV check switch.

P0442: Have you inspected the lines, charcoal cannister etc? Make sure the fuel cap is tight. The easiest way to check the system is to have someone perform a smoke test. I had a DTC on my car which indicated a EVAP problem, it turned out to be the Fuel tank evaporator Control Solenoid.

Have a code P1138 on 2003 Toyota Tundra - how do I fix ?

Swirl Control Valve Control System Performance Repair Importance Level: 3/3 Repair Difficulty Level: 2/3 Possible causes - Faulty Swirl Control Valve Control Position Sensor - Swirl Control Valve Control Position Sensor harness is open or shorted - Swirl Control Valve Control Position Sensor circuit poor electrical connection - Faulty Swirl Control Valve What does this mean? Possible symptoms - Engine Light ON (or Service Engine Soon Warning Light) P1138 Description While idling and during low engine coolant temperature, 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 coolant temperature, 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 swirl control valve is operated by the Engine Control Module (ECM).

The three P codes lean towards a faulty swirl control valve or actuator. If you are interested in further diagnosing the issue, I would be happy to help you.... I would just need your engine size.

Code P1138 in nissan

Code P1138 Swirl Control Valve

The Swirl Control Valve is part of the lower intake manifold... and, yes, this is something you can change out yourself depending upon your skill level.


The part will cost around $270 bucks plus the 2 gaskets which is another 12 bucks. Then the labor to do this repair is around 3.0 to 4.0 hours labor, what ever your area's hourly rate is.

If you have an extended warranty, it is possible this may be covered. Just give me your vin number and I can check for you. If you do not have an extended warranty, then these are the around about costs on the repair for this code.

Hope this help (remember comment and rated this).

What is a p1138 code for a nissan sentra 2005? i searched on the net it says switch control valve? what is this?

Swirl Control Valve
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.

Check engine lite came on i hooked up to the computer on the car and the code P1138 came up came up can you tell me what this means.

On the Nissan it indicates that the 'swirl control valve' is malfunctioning. The valve is located in the lower part of the intake manifold. Removing and cleaning the valve sometimes provides a solution to the problem.

That is a swirl control valve code. The swirl control valve is on the intake manifold and unfortunately the only way to get the valve is to replace the entire intake assembly, it is not available seperately @ this time. You will have to purchase this and the gasket from you Nissan dealer. Hope this helps.
