2006 Toyota Tundra Yaw Sensor

I have a 2006 Toyota Tundra 4.7L V8 4X4 Limited. I have a Yaw sensor that has gone bad. The mechanic disabled it for me so that it would not activate the ABS when cornering. This was done this summer, what I notice now is it will not shift into 4wd. When I engage 4wd high the 4wd light just blinks. I have three questions.

1) If the yaw sensor has been disabled, will it keep the 4wd from engaging?

2) Where is the yaw sensor located? On YouTube all I could find is that it is under the center consul. I took my center consul out and it is not there.

3) If I can locate where the Yaw Sensor is and order a replacement unit, is it simple a plug in or do you have to do anything else?

Thanks for your help.
