Technology drives innovation, especially in the automotive industry. In the past, when a driver was faced with the instant decision to make an aggressive move to avoid an accident, they had to rely on talent and a little bit of luck to keep the vehicle under control. In recent years, automotive manufacturers working with automotive safety experts like SEMA and SFI have developed advanced stability control systems that help a driver maintain control of the vehicle during evasive maneuver situations.

One of the most popular types of units on today's vehicle is known as the steering angle sensor. The steering angle sensor is a component that makes up the electronic stability program ESP.

Symptoms of a Bad or Failing Steering Angle Sensor

Although the names are unique, their primary function and the individual components that comprise the system are virtually identical. The steering angle sensor is one of the monitoring devices located near the front suspension or within the steering column.

In years past, this device was analog in nature, measuring the voltage changes that were created by the steering wheel and relaying that information to the vehicle's ECU. Today's steering angle sensors are digital and are comprised of an LED light that measures the angle of the steering input. This component is one that is designed to last the lifespan of the vehicle. However, like any other sensor, the steering angle sensor can wear out or fail completely due to multiple factors beyond the control of most vehicle owners.

When it does break or is slowly beginning to fail, it will exhibit a few common warning signs or symptoms. Noted below are a few of the common symptoms of a damaged, bad or failing steering angle sensor. In most cases where an issue exists with the electronic stability program, an error code is triggered and stored inside the vehicle's ECM.

This will also trigger the Traction Control Light to illuminate on the dashboard or instrument control panel. When the traction control is engaged, this light does not come on, as it's typically a default position that must be manually turned off by the driver.

When the steering wheel angle sensor fails, there is a malfunction indicator on the instrument cluster that alerts the driver that the electronic stability system has been disabled and requires service. In most cases, this warning light will be the Traction Control Light on most domestic and import cars, trucks and SUV's.

When the Traction Control Light is illuminated while the system is active, it's important that you contact a local ASE certified mechanic so they can download the OBD-II error codes and determine what problem exists that may impact the drivability and safety of your vehicle. Since the steering angle sensor is designed to monitor the actions and input provided by the steering wheel, it sometimes can relay false information to the ECM and create a potentially dangerous situation.

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.

In most cases, this will lead to a "loose" condition in the steering wheel, where the amount of steering input you provide is not reciprocated by the action of the vehicle.

If you notice that the steering wheel is looseor that the steering is not responding the way it should, contact a mechanic so they can inspect the ESP system and fix the problem quickly. Today's steering angle sensors are attached to multiple points within the steering system.

Since a front end alignment is designed to align the front wheels along with the steering wheel, it can cause problems with the steering angle sensor. It's very common for many mechanic shops to forget to reset or realign the steering angle sensor after they've completed their service. This can cause the symptoms above to occur, such as lighting the Traction Control Light, Check Engine Lightor impacting the drivability of the vehicle.This article shows methods of how to reset steering angle sensor.

Two methods are introduced in this article. And you can read related article or video to get more detail information in this article. Hope it is helpful! The steering angle sensor SAS is a critical part of the ESC system that measures the steering wheel position angle and rate of turn. The Steering Angle Sensor need to be reset or recalibrated after an alignment is per formed or parts in the steering system are replace.

For example:steering wheel,airbag spring contact,steering column,etc…. Step 1: Turn the steering wheel first as far as it will go anticlockwise and then as far as it will go clockwise Step 2: Turn off the engine and remove the key from the ignition Step 3: Remove driver side wheel, stop and pack vehicle Step 4: Turn off ignition, remove key, wait 10 seconds Step 5: Start engine, confirm normal Active Steering operation.

How to Replace a Steering Angle Sensor

This procedure can be used on any Mercedes. Some tools can even configure the size of tires. But, most tools recommend that the calibration be performed on a level surface. Launch X Series tools are able to reset steering angle sensor for multi brand vehicle manufacturer.

One essential segment is your controlling point sensor. There are two types of sensors used: analog and digital. Analog sensors rely on different voltage readings as the vehicle drifts through a corner at varied angles.

Digital sensors rely on a tiny LED light that transmits information about the angle the wheel is currently in and sends the information to the vehicle's computer. The steering angle sensor finds a disparity between the course your vehicle is traveling and the position the steering wheel is held at. Then the steering angle sensor balances out the steering and puts the driver in more control. If the vehicle goes into an understeering condition, then the sensor tells the computer to activate the brake module in relation to the rear wheel on the inside of the steering direction.

If the vehicle goes into an oversteering condition, then the sensor tells the computer to activate the brake module in relation to the rear wheel on the outside of the steering direction.

If the steering sensor is not working, the vehicle is unstable and an engine light will illuminate. Other common symptoms include the Traction Control Light coming on, the steering wheel feeling loose, and the car driving differently after a front end alignment. Step 1: Check to see if an engine light is on. If the engine light is on, it may be for the steering angle sensor or something else. Step 2: Get in the vehicle and drive it around the block.

Try to oversteer and understeer the vehicle and determine if the steering angle sensor is working or not. If the sensor is working, then the ABS module will attempt to top or slow down the rear wheels to correct the condition. If the sensor is not working, then the ABS module will do nothing. Step 1: Park your vehicle on a flat, hard surface.

Make sure that the transmission is in park for automatics or in 1st gear for manuals.


Step 2: Place wheel chocks around the tires. In this case, the wheel chocks go around the front tires since the rear of the vehicle will be lifted up. Step 4: Put on safety glasses.

The glasses prevent any object from coming out and hitting an eye. Step 5: Remove the mounting screws to the dash panel. Pull off the dash panel so you can have access to the mounting nuts to the steering wheel base.

Step 7: Remove the horn button from the steering column. Disconnect the power wire to the horn button.

Make sure that you catch the spring under the horn button. Disconnect the yellow power wire to the airbag, making sure that you mark the location of the airbag connection.

Step 8: Remove the mounting nut or bolt to the steering wheel. You need to hold the steering wheel from moving. Step 9: Get a steering wheel puller kit.

Install the steering wheel puller and remove the steering wheel assembly from the steering column. Step Remove the tilt lever with a pair of slip joint pliers.Hi there. This is a common issue on your vehicle. Most of the time this is caused by a problem with the steering angle sensor. The sensor stops reading properly which causes the steering to act like this.

There are also common issues with the steering module either failing or losing programming.

I usually start by scanning the module for any codes which would identify what the problem may be. If there are not any codes then I would try reprogramming the module to see if that takes care of it. If the problem persists then it may have an issue with the module itself.
