How to replace a Lexus LS400 Speed Yaw Rate Sensor?

1.Materials Needed for Repair

• Allen set (metric & standard sockets)
• Assorted pliers
• Assorted screwdrivers
• Combination wrench set (metric & standard)
• Disposable gloves
• Flashlight
• Metric and standard wrench set
• Pry bar
• Ratchet (3/8 drive)
• Socket set (metric & standard 3/8 drive)
• Socket set (metric & standard 1/4 drive)
• Torx socket set

2.Remove the Old Yaw Rate Sensor

The first thing you need to do is disconnect your battery before dealing with electrical products. Now you can find out where your yaw rate sensor is located. Most vehicles have the sensor under the center console or the driver seat but some are under the dashboard as well. Now you want to get in there and remove whatever parts of your interior you need to get access to that yaw rate sensor. Once you have gained access to the yaw rate sensor you want to unplug it and unbolt it from the vehicle so you can compare it to the new one.

3.Installing the New Yaw Rate Sensor

Now you want to remount the new sensor to the same location you removed the bad sensor from. Now you can plug it back in at this point I would go ahead and make sure it’s working by connecting a scan tool that can see the sensor or you might need to have a certified mechanic come do this part for you.

4.Programming New Yaw Rate Sensor

It’s possible you might need the sensor re-calibrated and some vehicles might require some special programming equipment so don’t forget this process will need to involve the dealership or a specialized technician with the right software and tools.

5.Installing Interior & Test Driving the Vehicle

Now that it has been tested and is working properly you can start to reassemble your interior. Just repeat the same process you did removing everything but in the reverse order to make sure you do not miss any steps or any pieces of your interior. You really want to make sure your yaw sensor is correctly working so you need to get it out on the open road and test it. Preferably on a road with turns so you can really make the sensor test the angles you are going to be driving through if everything is good you won’t have one issue and I would consider this a job well done. The Yaw Rate Sensor is tested for proper operation and the vehicle is road tested for proper operation.
