What code is C123F?
Code C123F indicates there is a problem with the signal that is originating from the steering column angle sensor. Turning the steering wheel clockwise decreases the signal and turning the wheel counterclockwise increases the signal.
Where is my steering angle 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.
What does a steering angle sensor do?
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.
How do you change a steering angle sensor?
Replacing the Sensor in 15 Easy Steps
- Disconnect the negative battery cable.
- Turn the wheel slightly to the left.
- Locate the sensor.
- Locate the bolt just under the sensor.
- Using a socket, loosen, but do not remove the nut on the bolt.
- With the steering wheel, position the front wheels straight ahead.
Can wheel speed sensor affect power steering?
This way you have the best of both worlds! The speed sensing steering enables power steering to continue to function at high speeds but allows for you to have more control when driving at highway speeds.
What happens if you unplug the speed sensor?
If it’s the wheel speed sensors (like for the ABS) the car will run but the ABS system won’t be able to do its job. If we’re talking about any engine sensors, the engine MIGHT still run, but it will likely run poorly or throw a check engine light.
Can you drive with a faulty speed sensor?
While it’s technically possible to operate your vehicle without a properly functioning vehicle speed sensor, it is strongly discouraged. A faulty VSS can negatively impact multiple aspects of vehicle operation—which is why it’s best to replace a bad speed sensor as soon as possible.
How do you diagnose a bad steering angle sensor?
Bad Steering Angle Sensor Symptoms
- Check Engine Light.
- Traction Control Light Illuminates.
- Heavy Steering Wheel Turning.
- Car Acts Strange After Wheel Alignment.
