Flap Actuator testing

@reeferjon What did you use to get this code? That's no Volvo/VIDA format. And that P200500 code is not present in VIDA for the ECM of your car. Scan the car with Vdash or VIDA.
Vdash is no diagnostic software. You can still try live data reading via the ecu diagnostic function of Vdash, but you will need to use a Super J2534 adapter or a really, really good DICE clone for this. Other adapters are to slow for this.
There should be at least 3 different ECM values that you can monitor. Demanded throttle position, and two values for the 2 sensors. Demand and sensors should show similar values.You can also use VIDA, which you can get in the depths of this forum, and perform a throttle activation via the ECM to test it's function while the engine isn't running. I'm not sure if Vdash also has that function, as it is not made with diagnostics in mind and therefore lacks lots of such functions.
As your code seems to be airflow related, have you already checked your MAP sensors? Like this? Your car has two of these sensors. One in the plastic pipe between the throttle body and the intercooler. And one as shown in the article I've linked. Both tend to get clogged and create lots of codes like MAF errors or low airflow codes.
If there is lots of carbon buildup on the sensors, cleaning the throttle body and MAF is also a good idea.
