What does a steering torque sensor do? The steering torque sensor is integrated in the electromechanical power steering and provides the customer with information on the steering torque. The sensor records the torsion bar angle required for the steering movement.
What does the steering torque sensor do?
What this sensor does is a crucial little task that makes it possible for the power steering to go and do its job. This is taking the amount of torque the driver applies to the steering wheel when steering and then sending those signals down to the sensor which then in turn sends those signals over to the power steering system.
What is the function of the steering angle sensor?
The steering angle sensor measures the steering wheel position angle and rate of turn. It is placed in the steering column of the vehicle. More than one angle sensor can be used to provide redundancy and data validation. The steering control program would generally require two signals from two angle sensors to confirm the steering wheel position.

What happens if my steering torque sensor goes out?
If the steering angle sensor fails to deliver a correct signal, the traction control light will illuminate. You may also notice other warning lights like the ABS or the Airbag light.
Is steering angle sensor and steering torque sensor the same?
Steering torque: The sensor records the torsion bar angle required for the steering movement. Steering angle: The sensor measures the angle and speed of change in the position of the steering wheel.
Why do we use torque sensor?
Torque sensors are a device used to measure twisting or turning forces. They can be either static or dynamic and are able to measure turning forces in either clockwise or anti-clockwise directions.
What is EPS torque sensor?
One of the most critical parts in an EPS application is the torque sensor, which collects steering direct and road resistance input and communicates the torque, or the amount of turning force, back to the EPS control module.
Does steering angle sensor affect power steering?
Since the steering angle control is there to assist in power steering corrections, a faulty one may cause the power steering to work incorrectly. It may receive the wrong signals or no signal at all, causing it to make incorrect adjustments or offer no assistance.
What happens if steering angle sensor is not reset?
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.
What are the types of torque sensor?
There are two main types of Torque Sensors: Reaction Torque Sensors or Rotational Torque Sensors.
How do position sensors work?
The position sensor is a device that collects information on the precise position and movement of an object. The information can be obtained by direct contact with the object or remotely using magnetic sensors. It can also detect the thickness of a part, the level of a fluid or the angle of rotation of a shaft.
How is motor torque tested?
1) Electrical Power Meter A relatively simple method to estimate torque on the output shaft of an electrical motor is to measure its electrical power input via an electrical power meter. The meter calculates the power input by measuring the current and voltage in the line driving the motor.
What causes electric power steering failure?
Today's electronic power steering systems may fail due to issues with the mounted electric motor. In particular, excessive heat on the motor is likely to cause the failure modes. Infiltration of the system environment by water, dirt, or other contaminants will also likely lead to EPS failure.
What causes the EPS light to come on?
The EPS light comes on when the computer detects an issue with the vehicle's electronic power steering system. If the computer detects an issue with the system it will set off the warning light to notify the driver of... Your vehicle is equipped with electronic power steering (EPS).
What sensors are needed for EPS systems?
Generally speaking, an EPS system consists of three different sensors: The steering wheel position sensor, which derives the absolute position of the steering wheel. The steering torque sensor, which converts torque applied to the steering wheel by the driver into an electrical signal for processing.
Where is the steering torque sensor located?
The sensor sits on the steering pinion. A pole wheel is fitted on the input shaft, which is connected to the steering pinion by means of the torsion bar. When the driver applies torque to the steering wheel, the torsion bar is rotated and, in turn, the magnet relative to the sensor.
What is a steering angle sensor?
Steering Angle Sensor. The steering angle sensor measures the steering wheel position angle and rate of turn. It is placed in the steering column of the vehicle. More than one angle sensor can be used to provide redundancy and data validation.
Can wheel alignment affect steering angle sensors?
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.
Can you reset a steering angle sensor?
Go into the Wheel Alignment System, select Wheel Alignment, then Reset Memory and you will receive a message: Turn the ignition key off and wait for at least five seconds. After five seconds, step on the brake pedal and start the engine. The step by step instructions will guide you through.
What Are The Symptoms Of A Failing Steering Angle Sensor?
Typically they don’t fail very often since they are designed to last the lifespan of your car. Even though they are supposed to last, they still can wear out over time and fail. There are two major warning signs that will alert you if your steering angle sensors are failing. You should always be aware of these symptoms so you can detect if yours start to fail. You will want to get them fixed as soon as possible if they do.
What happens if your steering angle sensor is not installed properly?
When your steering angle sensor is not installed properly, it will collect inaccurate data. When this happens, your electric power steering module could provide false input or adjustments at the incorrect time. If this happens, your steering wheel will feel loose.
Why is it important to check steering angle sensors?
It is very important to make sure the steering angle sensors are checked after an alignment happens. If they are not checked and working properly, the driver will be fighting the electronic stability control module while driving. This is very bad because the angle calculations will be off and this could also result in unexpected direction changes. The direction changes can occur while the wheel is being turned in on direction. If you get your parts realigned in your steering wheel system, it is important to check out your steering angle sensors to ensure they are working properly.
How do analog steering angle sensors work?
Analog steering angle sensors are wired with a 5-volt reference. The sensors can be tested from a port under the steering column. It is so important to make sure these sensors are working properly since they have such a crucial role. If these sensors are failing, they won’t be able to accurately determine the angle of your car’s turn. So you might be wondering to yourself how do these steering angle sensors actually work?
What is torque sensor?
If you have electric power steering in your car, you might have a steering torque sensor. This sensor detects how much for a driver is putting on the steering wheel when they are turning. This sensor will twist slightly as your steering wheel shaft is being turned.
Why is electronic stability important?
The electronic stability control system is very important. This system takes in all the information from the sensors and calculates the correct angles of the steering wheel turns. Once the ESC module gets all of the signals, they are compared to the software within the ESC system. This is important so it can compare angles and determine which ones are the best for your turning situation. If the ESC module detects any irregularities, it will correct them itself and allow the driver to maintain control over their car.
Why do auto repair shops forget to reset steering angle sensors?
Oftentimes auto repair shops forget to reset the steering angle sensors after completing an alignment. This is a pretty common mistake and an easy fix. If you start to experience either of the two symptoms above, you need to check with your local repair shop to make sure those sensors are working correctly. They will be able to easily fix this problem if they forget to reset the steering angle sensors. Don’t wait to take your car into your local repair shop.
