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
Hi there. If the codes are coming on for the steering angle due to either the sensor failing or the plug not plugged in all the way. Check the harness on the steering sensor and see if its plugged in. If the harness is plugged in and has not moisture on it, then the sensor has probably failed. You can have the vehicle realigned, but if the sensor has failed, it will not correct its self. I recommend replacing the steering angle sensor. If you need further assistance with the steering angle sensor, then seek out a professional, such as one from Your Mechanic, to help you.

Performing a Steering Angle Sensor Reset
Over 40 million vehicles on the road today require a reset/recalibration of the steering angle sensor (SAS) following a wheel alignment, as instructed by the vehicle manufacturer on certain cars equipped with Electronic Stability Control (ESC).
Calibration of a steering angle sensors may be needed after an airbag deployment, structural repairs, or a wheel alignment. Calibration is normally done with a scan tool. Sometimes the vehicle will need to be on an alignment rack.
This can cause the vehicle`s stability control system to provide incorrect steering adjustments, resulting in either a loose steering wheel, or the steering not responding in the way it should.
Calibrating your ADAS system after a wheel alignment ensures that your sensors` performance is functioning as it should. When the sensors are calibrated correctly, drivers can receive the full safety benefits that ADAS systems provide.
Every time the vehicle`s battery is disconnected or discharged, the Steering Angle Neutral Point memorization and the Steering Sensor Zero Point Calibration must be performed.
The steering angle calibration is as simple as centering the steering wheel, turning on the ignition switch, then turning lock-to-lock starting left then right and returning to center.
These are torque to yield bolts. The old ones should not be reused.
Sensors and measuring systems, among other measurement tools, are calibrated to check their accuracy and repeatability. Calibrated sensors are necessary for precise, consistent, and repeatable measurement outputs. Calibration is one of the crucial conditions for effective quality assurance.
The most common way a shop will encounter steering angle sensors is related to an operation that requires the SAS to be calibrated. It may be necessary due to changing or removing certain parts that can affect its operation. Typically they will need to be calibrated due to a wheel alignment as well.
Error code U0126 means there`s a loss of communication with your steering angle sensor module. The steering angle position sensor reports the angle at which the steering wheel and front tires are positioned. The vehicle uses this data to help in advanced maneuvers usually associated with accident avoidance.
As the steering wheel is turned, the SAS produces a signal that toggles between 0 and 5 volts as the wheel is turned 360º. As the wheel is turned lock-to-lock, the voltage will reach 5 volts three times and 0 volts three times.
When the sensor is faulty, misaligned, or damaged, the information it reads and sends to the vehicle`s on board computer is inaccurate. This can cause the ESP to provide steering input or adjustments at the wrong time.
The purpose of the relearn is to share the new TPMS sensor IDs to the vehicle. This allows the sensors to “talk” to the vehicle and alert the driver if any tires have low air pressure or if there is a malfunction with the TPMS system.
Most sensors are subject to ageing, and it very much depends on the design of the product and the accuracy required. Higher-accuracy measurements require more frequent calibration, ranging from once every six months.
Disconnecting the battery will not likely fix the buttons on your steering wheel.
We can perform repairs, replacements and recalibrations for your car`s steering angle sensor, allowing it to function normally.
What Happens If You Don`t Recalibrate the ADAS? If the ADAS system is left uncalibrated, the car will not be able to respond correctly to the situation and can either not work at all, or it will interfere when there is no need. This often means braking for no reason, as most ADAS systems involve brake assist.
Because it`s an electronically-controlled system, it`s easy to alter the characteristics of electric power steering to suit individual preferences. Specifically, you can alter the steering weight to radically improve steering feel and high speed stability.
The steering-angle sensor is based on Giant Magnetoresistance technology (GMR element) and provides an absolute steering-angle value over the complete steering-angle range (multi-turn sensor).
The steering angle sensor (SAS) determines where the driver wants to steer, matching the steering wheel with the vehicle`s wheels. Located within the steering column, the steering angle sensor always has more than one sensor packaged together in a single unit for redundancy, accuracy, and diagnostics.
If a car`s suspension is worn or damaged, unintended body roll and movement can occur and cause torque steer. Worn or damaged control arm bushings, CV joints, and other components play a role in torque steer. Engine mount tolerances or damage can cause excess movement during heavy acceleration, as well as torque steer.
All you need to do is turn off your engine, then restart it so the light can reset. In most cases, it should come back on, and this only indicates that it may have thought it suspected a problem due to a mistake in the computer system.
To reset a sensor, turn the device over and look for the circle on the back labeled “RESET” (See photo below). Insert a paperclip or other thin wire through the label to make a hole, and depress the reset button. You`ll feel it `click` when it is depressed (you should not have to press very hard).
Programming a sensor is an essential step when working with universal or “programmable” TPMS sensors. These sensors come completely blank out of the box and they need to be programmed (also referred to as “activated”) to the unique make, model and year of the vehicle being serviced.
