Hi,
I believe these are passive sensors. If you have a live data scan tool, you can check to see if there is a signal from each wheel and if they indicate the same speed.
If you don't have access to a scanner, you can check them manually. You will need a multimeter or voltmeter.
Here is a link that explains how to do it:

Let me know what you find.
Take care,
