Hello everyone, there was a problem with the car today
I found it on OBD2. Code: P2006 (Intake Manifold Air Control Actuator, Bank 1- Actuator Closed)
TRC off / DCT LED is on. I'm worried. What should I check?
The swirl valve is located on the intake manifold on the backside of it, you can apply direct voltage to one pin or the other (for no more than 30 seconds) to each pin one at a time to ensure the valve actually moves left to right.
If you measure the resistance of the swirl valve, it should be between 1-19 ohms at 20°C (68° F).
To check the wiring supplying voltage to the swirl valve itself simply check that there is battery voltage on pin #1 which I believe should be light green, and make sure a good ground is also present on pin #2 which should be black.
Ultimately if I had to throw a dart at a causal part, I would say the swirl valve needs to be replaced, the downside to that is it is integrated into the manifold itself so you have to replace the whole intake manifold.

Have you had any service done to the vehicle recently? Such as spark plug replacement.
I don't think anyone has reported this issue on an IS250 yet, so you could be the first.
It's possible the issue could be with the lower intake portion where the swirl valve assembly is located, but until you check further it would just be a guess to replace it.
If you are able to remove the upper intake, then you could see better what is happening inside the lower intake.
I had the P0206 on my 2014 Lexus IS 250. I went through a few parts. Initially, I replaced the #6 fuel injector and that did not fix it. Afterwards I replaced the Injector Driver and then the Engine Control Module. The car ran after I changed each component; however, the check engine light would come back on after I would drive several miles and on hard accelerations. The fuel injection wire harness was the cause of the problem. Some of the insulation had deteriorated off of the wires inside the conduit for the harness. I replaced both bank wire harnesses.

Well, the car still isn't fixed. I took it to the Lexus dealer today. I'll advise of the repair once I get it from the Lexus dealer.
