ABS Quuestion

My '87 944S starts up with no warning light about ABS, but after the wheels have turned for about 100yards, the exclamation mark and the ABS warning light come on, I'm pretty sure that one or more of the wheel sensors is not reading correctly-- is there an easy way to measure them?( continuity, or do I have to measure them with a 'scope)
Thanks,
Jeff

Wheel speed sensor is failing. It's not a continuity problem, or it wouldn't likely pass bulb check (turn lights off after key-up). You either need to pull codes or try swapping sensors.

I pretty sure there will be a lot of rust and dirt on the sensors, going to try cleaning them first
