Abs wheel sensors

[Allan.adams]

What diagnostic tool will help me find out if a wheel sensor is bad. Durametric does not seem to have that option. Any suggestions on how to address this problem would be greatly appreciated..

 

Thanks in advance..

You will likely need a PST2, PIWIS, PIWIS 2, or PIWIS 3 to diagnose wheels sensors.

Ouch, that’s not going to happen for me. ? any other way of telling? 2 hr drive to the nearest Porsche shop. 

I can clear the fault with Durametric, it does not come back on when started, when the car moves over 3mph the light comes on, s/b wheel sensors-no?

 

thanks for the help

If you are not going to have it scanned for which speed sensor is bad, then all you can do is replace them all (2 front and 2 back).  I cannot think of a logical process of elimination to determine a bad one.   They work off an induced electromagnetic pulse signal within the wheel carriers.  I guess you could unplug each one and see if there is continuity across the terminals, but I don't know how far that will get you in determining which one is bad.
