CMOS sensor dirt?

I have a high range of Canon 1DS Mark II. How I can know if a dirty CMOS sensor is affecting my photos? I have a few spots in the same place all my images. The mirror and the lens seems to be clean. Could this be the sensor, and that keeping getting help?

1) Wearing ANY put the camera in Av (aperture priority) or manual mode. 2) Change the opening of f/16 f/22 o. 3) Take a picture of a white background (such as a sheet of A4 paper or a blank screen on your computer) 4) You can: i) Approach the camera image as you move around you will see dark spots. If you have dust on the sensor. Ii) Open the image in photoshop and autolevels use and clearly show that the dark spots. (I repeat this process after the cleaning and I think this is precisely how to clean and validate my * Clean) 5) You can get a professional cleaning for about $ 50 or you can get a solution for Eclipse and PecPads on the same cost and clean for himself about 200 times. I can use the Copperhill system (you need to get the right size swipe sensor-18mm for 5D and 1DsMk.2) in my camera and its really no big deal. ____________________________ * Please note that you are taking test images at f/22 and aims to dispose of Large Black dots. There may be small, translucent spots, especially on the edges. Do not bother with them, they do not appear in most of your pictures (unless you shoot only tiny openings as f/32 and f/22).
