Steering Angle Sensor Calibration
Error in steering angle sensor calibration data.
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 measures the direction of the steering wheel. If the calibration is off, the computer can’t tell how far you've turned the wheel, which can mess with your stability control.
What the computer is actually seeing
The computer checks the steering angle sensor's data against expected calibration values. If the readings are out of the expected range, it triggers this code.
What a healthy reading looks like
Steering angle should return between -45 to +45 degrees for normal operation under static conditions. A stable calibration value should not vary more than 2 degrees when stationary.
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.
- 11. Check the wiring and connections to the steering angle sensor for damage or corrosion. If found, repair the wiring or replace connectors. Decision point: If wiring is good, proceed to step 2.
- 22. Verify the steering angle sensor operation using a scan tool. Check for voltage input/output. Expected values are typically 0.5 to 4.5 volts at rest. If voltage is outside this range, replace the sensor. Decision point: If voltage readings are normal, proceed to step 3.
- 33. Perform a steering angle sensor calibration using the vehicle's scan tool. This is usually done through a calibration process in the tool's menu. If calibration is successful, check for code reappearance. Decision point: If code returns, consider sensor replacement.
Common causes
- Faulty steering angle sensor
- Improper sensor calibration
- Wiring issues to the sensor
- Faulty steering rack or column
- Corroded connectors
