Invalid Data Received from Steering Angle Sensor
The ABS control module has detected invalid data from 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 measures how far the steering wheel is turned, and if it sends bad readings, the ABS system can't work right, which may affect braking performance.
What the computer is actually seeing
The ABS control module expects to receive a valid voltage signal corresponding to steering wheel position, typically between 0.2V (full left) and 4.8V (full right). Unexpected or out-of-range voltages indicate a problem.
What a healthy reading looks like
Steering angle sensor should output between 0.2V and 4.8V based on the steering wheel position. Closer to 2.5V indicates straight ahead.
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. Inspect the wiring and connectors at the steering angle sensor for any obvious damage or corrosion.
- 22. Check the steering angle sensor output with a multimeter; you should see a voltage between 0.2V and 4.8V corresponding to the steering position.
- 33. If the voltage is out of range, replace the steering angle sensor and retest.
- 44. If the sensor output is good, check for software updates or calibration requirements for the ABS module.
- 55. If a module is needed, confirm with the manufacturer guidelines before replacement.
Common causes
- Faulty steering angle sensor
- Damaged wiring or connectors to the sensor
- Faulty ABS module
- Calibration issue with the steering angle sensor

Frequently asked questions
Is it safe to drive with this code?
It’s not ideal—braking may not perform as expected, especially in low-traction conditions.
Will this problem come back after a reset?
If the underlying issue isn't fixed, yes, the code will likely return.
Why does this code appear with ABS issues?
The ABS system relies on accurate inputs from the steering angle sensor to function properly, and if it gets bad data, it triggers this code.
