Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello my name is***** am an ASE Master Technician and I am glad to help you out with your question.
Is the abs light on the dash on?
Most common cause for the abs to activate is the abs module.
could also be an abs pump motor problem.
This is part of the hydraulic control unit. try to get the abs module and control unit as an assembly if going used. The pump motor is in the HCU.
HYDRAULIC CONTROL UNIT (HCU)
Removal & Installation (Rear Wheel ABS)
Disconnect HCU harness connector from CAB. Disconnect brakelines from HCU. Remove HCU mounting bolt and remove HCU. To install, reverse removal procedure. Tighten HCU mounting bolt to specification. Tighten HCU brakelines to specification. See TORQUE SPECIFICATIONS . Bleed brake system. See BLEEDING BRAKE SYSTEM .
Removal & Installation (4 Wheel ABS)
The CAB and HCU are integrated into one unit, the anti-lock control assembly. HCU replacement requires replacement of HCU and pump/motor as an assembly. See Figure . Remove the anti-lock control assembly from vehicle and separate CAB from HCU and pump/motor assembly. See ANTI-LOCK CONTROL ASSEMBLY (4 WHEEL ABS ONLY) .

It may not set a code. if you have codes for the sensors I would focus on diagnosing those codes first. Have you had it rescanned after replacing the sensor?
Do you know the code numbers?
You really need a scan tool to get the codes, and also view live data of the actual wheel speed. You could see if they are reading in real time with a scan tool.
You don't know for sure that the sensor is the problem. You could take it to a shop for diagnosis and then replace the parts yourself.
