Hello,

The Intake Manifold Tuning Valve (IMT) is located on the front side of the intake manifold. It will be on the top side of the manifold facing front of the car.
Your vehicle has 2 IMT valves, one upper one lower. I have attached the diagram with the location. The IMT valves controls the spark.
Also attached a basic diagnostics for the IMT valve. Many times the connector becomes faulty and cuts power to the valve. So be sure to check to see if you are getting power to the IMT valves.

Please let me know of any questions.

Thank you.

Hi, I recently changed the spark plugs, during an acceleration the engine fault warning light came on! I checked, and this problem came up.
Where do I have to act to repair the damage?
Thank you

Code P1111 is just a system readiness code. The P1549 gets triggered due to the intake manifold tuning valve (IMT) not getting proper power or having wiring or functionality issue.

I have attached the trouble shooting guide for code P1549 below. Follow those steps, as it can help you determine the issue.

Let me know what you find or if you have any questions.

Thank you.

These are about the best images that the software allows us to upload. So unfortunately, we do not have an option to have any higher resolution images for this specific vehicle.
Thank you.
