Yaw rate sensor location
 

last week I was driving my '06 model W203 down a straight road doing around 45 mph when all of a sudden the breaks locked up by themselves as if someone is stepping on the brake pedal really hard. I replaced break light switch, but the problem still remains. Where can i find the yaw rate sensor?

In the trunk...why not have the codes read from the ESP traction system 1st?
