FAQs

How do I fix the U0126 code? ›

Replace or repair your vehicle's battery. Replace or repair your SAS control module. Make sure there's power going to your vehicle's SAS module, replace or repair any damaged or defective wiring and circuits.

Where is the steering angle sensor module located? ›

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 happens if you don't calibrate steering angle sensor? ›

If the steering angle sensor is not calibrated, it could lead to the false activation of many ADAS systems.

What happens when a steering angle sensor goes bad? ›

When a steering angle sensor fails, the vehicle may experience the following symptoms: Excessive play in the steering wheel. Steering warning light illuminated in the dash. Electronic Stability Control system is disabled.

How do you manually reset the steering angle sensor? ›

Turn the steering wheel fully to the left and fully to the right at least 3 times. Turn the key to the “OFF” position and restart the car. If this doesn't work, repeat the process but disconnect the battery first.

Do you need to reset steering angle sensor? ›

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).

How do you calibrate the steering angle sensor? ›

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. But, if you follow the correct procedure, you must perform a full system calibration.

Does steering angle sensor affect power steering? ›

Your vehicle's power steering and brake control units require data from steering angle sensors. Once your vehicle's computers detect that there's an issue, they will trigger warnings, such as the stability control and electronic power steering lights.

Will disconnecting the battery reset the steering angle sensor? ›

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.

Can wheel alignment affect steering angle sensors? ›

That is the steering wheel is at 12 o'clock position when the wheels are straight ahead. Steering angle sensors follow this setting. Thus a correctly carried out tracking adjustment should leave the steering angle sensor unchanged.

What is the U0126 code? ›

U0126 - OBD II Code: Lost Communication with SAS Module.

Can a steering angle sensor cause transmission problems? ›

The steering angle sensor can cause drivability issues that can be misinterpreted as transmission faults. In the case of sensor signal failure, a fault code will be stored in the PCM. However, if the sensor is giving inaccurate data to the PCM, this may not be detected.

Does a steering angle sensor affect ABS? ›

What and Why of Sensing the Steering Angles. Measuring the position angle and rate of turn is critical for Electronic Stability Control (ESC) systems, Anti-lock Braking Systems (ABS) and Advanced Driver Assistance Systems (ADAS).

What causes lost communication with ECM/PCM? ›

The U0100 code means there's a loss of communication between your PCM and a particular module. A malfunctioning PCM, a faulty control module circuit, and a fault in the data bus are some of the common causes of the U0100 code. The most common symptom of the U0100 code is an illuminated check engine.

How do I calibrate my steering wheel sensor? ›

Turn the steering wheel until the vehicle is at the full left steering lock. Tap the "Left" calibration button when the current sensor count displays a stable value at the extent of possible steering travel. Turn the steering wheel to the center position and so the vehicle is driving straight ahead.

How much is a bad steering angle sensor? ›

An aftermarket steering angle sensor replacement costs around $100 to $250. Some sensors are priced higher depending on their brand and specifications. Labor costs for a steering angle sensor replacement can go anywhere between $100 and $500.
