ABS Speed Sensor 93 400 SEL

My ABS light is on and my speedometer doesn't work. I disconnected my ABS/Speed sensor head at the wheel and it had trash around the head. While cleaning that off I noticed it had a strong magnetic pull to it. What all can I check before replacing the harness?
Front drivers side wheel speed sensor is used for both ABS and speedometer, does this help?
 
Well said and the most prudent way to do before changing the sensors.

Samosali you are right there are 4 ABS sensors on 140's
Correct and each one has extra assignments besides wheel speed. The front left or drivers side is also allocated to the speedometer so you have your answer.;)
