2009,Had the steering rack replaced and now the steering angle sensor is acting up after a front end alignment.

Power steering was getting hard in steering. Had it checked, replaced pump and belt. Found to be the Rack and pinion going bad, Had the Rack replaced by a local mechanic after which the Steering Angle Sensor (ESP/BAS light) and Anti Skid light keeps coming on as well as. Local mechanic took it to Dodge dealership for eval. Dealer said needs knew Steering Angle Sensor. Instructed to get a front end alignment and they ordered sensor. I have done the alignment and am wondering if it should be checked and recalibrated before replacing since it was not done before alignment. Dodge dealer wants $450
