In my case DOC, all the tires were the same.

When the problem first started it was guaranteed to happen at least twice daily. After I switched the sensor it only happens maybe once a week. The power doesn't cut out every time like it used to, and all three of my first lights (ETS, ABS and BAS/ESP) come on sometime while driving after the pulsing happens. Sometimes they reset after the vehicle has been sitting off, sometimes they don't.

When I initially took it to the dealer for diagnosis, they did pull some codes for the Lateral Accel Sensor, the Left Front Wheel Speed Sensor and a stored code for the Yaw Sensor. They pulled these codes from somewhere under the hood on the left side of the engine I believe.

I have had trouble locating the Left front wheel speed sensor and the Lateral Accel Sensor. Like I said in previous post, I will replace the old Yaw sensor with the new version one first before I move on to the other two.
