Wheel Speed Sensor? I've suddenly had "TCS OFF" and "ABS INOP" lights appear. I've done a search and it sounds like it's likely a wheel speed sensor? My question is if that assumption is correct, and if so...where are those located? And what should I be looking for - like do the sensors go bad or is it usually a wiring issue? Car is a 2000 WS6 and I've not done anything new/different to kick off this light, if that makes a difference. Thanks!

Look for a wire going to the wheel hub from the backside, if it's still there of course lol, if the wire is still there then it's either the sensor or the hub itself or the wiring before the connector to the hub.
Going to need a scan tool that'll show individual wheel speed and see which one's output is 0.
I've actually seen where it's the abs actuator on Toyota camry's that make the TC/ABS light come on, $2000 just for the part alone.

If you get the car scanned, you may be able to confirm a specific offending wheel. (Not all scanners will scan the ABS module. You need to find one that does both PCM and ABS codes.)
The sensors for the front are built into the hubs and the rears are separate sensors.
In addition to sensors being bad, they can come unplugged or have a wire cut - so you may want to check that first.
