Steering Angle Sensor Calibration Fault
This code indicates a problem with the calibration of the steering angle sensor.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The steering angle sensor monitors the position of the steering wheel. It tells the computer how much and in which direction you're turning the wheel. If it's not calibrated, the system can't accurately determine your steering input, which can affect handling and safety features.
What the computer is actually seeing
The computer expects a signal from the steering angle sensor that represents the current steering position in volts (usually around 0.5 to 4.5 volts depending on the angle). If it doesn't receive the correct signal, it triggers this fault code.
What a healthy reading looks like
Steering angle sensor output should be between 0.5V (full left) and 4.5V (full right). At center, expect around 2.5V.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 1Check the wiring and connector to the steering angle sensor for damage or looseness. Secure them if needed.
- 2Use a scan tool to read live data from the steering angle sensor. Verify that the voltage readings match expected values (0.5V to 4.5V). If not, proceed to the next step.
- 3If the sensor voltage is out of range, check the signal ground and power supply to the sensor. Repair any wiring faults, then retest.
- 4If the wiring and power supply are good, replace the steering angle sensor and calibrate it according to the manufacturer's procedure. Retest the system.
Common causes
- Disconnected or damaged wiring to the steering angle sensor
- Faulty steering angle sensor
- Improper sensor calibration after steering component replacement
- Interference from other systems or sensors
- Steering column issues affecting sensor position

Frequently asked questions
Is it safe to drive with this code?
It's generally safe to drive, but the vehicle's handling could be compromised, especially if stability control features are engaged.
Will this code come back after clearing?
If the underlying issue is not resolved, the code will likely return upon driving conditions that require steering angle data.
Why does this code appear after replacing the steering wheel?
Replacing the steering wheel can impact the sensor's position or calibration, leading to this fault code.
