1998 Dodge ram 1500 5.9 liter v8. I have replaced the abs sensor in the rear three times with new sensors. Still have the abs warning light and no speedometer. Going crazy. anyone have this problem before. If so what is the fix ? Any and all help is appreciated very much.

 

Need to trace the wiring... are you getting 5 volts back TO the sensor???

 

I thought these sensors generated an a/c voltage for the reading?

 

In the sensor it reads a wave form which is AC but the sensor converts that to a return voltage from the 5 volt reference signal.

 

That is correct, the FSM describes the system as such. Modern active wheel speed sensors are powered and create square wave signals.
