What happens when steering angle sensor is bad?
When the sensor is faulty, misaligned, or damaged, the information it reads and sends to the vehicle’s on board computer is inaccurate. 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.
What does a steering angle sensor do?
The Steering Angle Sensor is an important part of a vehicle’s safety system. It transmits the steering wheel’s rate of turn, wheel angle, and other important data to the specific vehicle’s computer. If there is a fault in the signal, the computer can disable the vehicle’s stability control.
How do you test a steering angle sensor?
To test the SAS, you have to back probe a connector that is typically under the steering column. As the steering wheel is turned 360 degrees, the SAS produces a signal that toggles between 0 and 5 volts. As the wheel is turned lock-to-lock, the voltage will reach 5 volts three times and 0 volts three times.
Do you need to replace the steering angle sensor?
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. Was this answer helpful? Thank you for your feedback!
Why is my steering angle not coming on?
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.
How is the steering angle calibration process done?
Sometimes the vehicle will need to be on an alignment rack. The calibration process is normally done by putting the wheels in the straight forward position, and then zeroing out the sensor with a scan tool. Being informed on these systems is important to a complete, safe, and quality repair.
Why did my steering rack need to be replaced?
Q: 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.
