hey guys i have a 99 sport and my brake and abs light are on and the speedometer works intermittently does anyone know what this could be i do have a lose caliper but that wouldnt make the speedometer not work could this be the sensor?

 

Rear wheel speed sensor on the differential.

 

check the wiring first and the connector doesnt have that green powdery sh*t (corrosion) at the rear sensor. most of the time its the sensor gone bad though
