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.

code P1138 in nissan - 9b9c504.jpg

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).

SOURCE: what is a p1138 code for a nissan sentra 2005? i

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.

What exactly is P1138 because I haven't been able to locate it in any OBD2 code books and what is the cause

Of coarse you haven't
You only find the Generic OBD Codes, required by the Govt
The dealers took your tax dollars, and now want your vehicle back, so they can take more money
The P Codes and others, are Manufacturer Specific

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.
