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
Experienced mechanics share their insights in answering this question :
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.

Could you give me an estimate for the following work on my 2006 Toyota Tundra sr5? Replace front brake pads and refinish both rot
ANSWER : Hi there. On your list of items include a few things that our mobile mechanics are not able to offer; such as the wheel alignment and machining work on the brake rotors. You might want to contact a local brake and suspension shop that can complete everything in house.

Does the whole steering column need to be replaced in order to replace a fried steering column module?
ANSWER : I would ask the mechanic for the exact part number of the electronic component that he believes has failed. Or, at least have him "name" the part and indicate where in the column assembly the part resides. The steering column is made up of many parts, most of which are separately serviceable. As discussed below, limp mode (reduced power) has many, many causes. Consequently I would also ask the mechanic to explain to you EXACTLY how he arrived at his diagnosis and ALSO have him show you the exact test results, on a diagnostic tool, multi-meter, or scope, that has led him to conclude that the particular "module" has to be replaced. With no evidence and no intelligible confirmation you would be taking a risk.

YourMechanic does offer a reduced power (limp mode) diagnostic. If you request a reduced engine power diagnostic the responding certified mechanic will give you confirmation of the cause of the issue in your case. Typically, a vehicle’s powertrain control module (PCM) will have stored one or more diagnostic trouble codes that will identify the "general area" in which the fault lies in the engine management controls. Although the throttle control system is a common trouble area with reduced power, there are quite a few other components and systems that could come into play and, of course, there is always the possibility of multiple, or "coincident", faults. Here are some of the possibilities that YourMechanic dispatched technicians would consider:

Defective throttle position (TP) sensor
Defective oxygen sensor
Defective accelerator pedal position (APP) sensor
Loose or damaged wiring
Defective throttle body
Defective powertrain control module (PCM) (not typical; ONLY if a long, long list of other possibilities is ruled out)
Any fault/error that will affect drivability function
Any fault/error that will affect vehicle performance
A fault/error in the emissions system
A fault/error in the throttle control system
A fault/error in the transmission control system

If you request the recommended diagnostic the mechanic will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Very loud pop when turning sharp left leaking transmission or power steering fluid where steering column meet rack
ANSWER : Hi there. If everything else has already been installed from the donor vehicle then it sounds like the high pressure hose is all that you need to install. The hardest part of doing this is the routing. One thing you may also want to double check is that the donor vehicle and your 2003 Escape have the same rack. There are different models depending on the model and the size of your wheels. You need to install the pressure line first, but if it does not line up then you may have the wrong rack installed. If you would like some assistance installing this hose, consider YourMechanic, as a certified mechanic can come to you to [replace your high pressure steering hose] https://www.yourmechanic.com/services/power-steering-pressure-hose-replacement

I have a bad oxygen sensor, bad power steering sensor, and a bad cam shaft sensor? Should I replace any of them?
ANSWER : When you say you have three bad sensors I can only assume you have had them tested and the end result is three bad sensors. If they tested bad then they should be replaced. The power steering sensor senses the load of the steering on the engine so it can raise the idle during parking maneuvers. The O2 sensor is used for fuel control and it may effect engine power and fuel mileage. The camshaft sensor cay cause no starts, engine running problems and all three will turn on the check engine light.

Can you replace just the hydraulic line in steering rack or does the entire rack have to be replaced?
ANSWER : The individual lines can be replaced but that is only worthwhile if there are no other faults with the rack. Also, inasmuch as the rack will probably have to be removed from the vehicle to replace an individual line, there is the related risk that you go to all that trouble, and expense, only to find other issues with the rack once it is re-installed in the car. But, again, to answer your principal question, the individual tubes can absolutely be replaced and they can even be fabricated right in the field. If you desire an inspection and advice as to the least cost and most effective repair strategy for this issue, please schedule a leak diagnostic and the responding certified mechanic will explain your options and ultimately get this resolved for you. If you have further questions or concerns as you decide what to do, do not hesitate to re-contact YourMechanic because we want you to make the most of your repair dollars and help you to get the best possible results.

Hello my car had its steering rack replaced 5 months ago the garage never put the heat shield back on and now the steering rack is
ANSWER : Hello, thank you for writing in. The shields that are mounted on the bottom of the car provide the most protection from water and road debris. While they do provide this protection, failure of the rack and pinion should not have occurred after being exposed for 5 months. If weather conditions in your area are extreme right now, that may be a factor to consider, but you need to look into the situation a little further. Check to see if the rack was new, used, or re-manufactured when it was put in. Verify what kind of warranty the unit came with if any, and find out why the heat shield was not reinstalled. The company will have to take some responsibility for that. If the unit was used, it may not have a warranty, but any new or re-manufactured parts (used but rebuilt) should have a warranty. Between the manufacture of the rack, and the shop who did not reinstall the shield, you should be getting assistance somewhere along the line in replacing the unit again. For more help replacing the unit, or getting an inspection of the problem, contact our service department about scheduling.
