Steering Angle Sensor Signal Invalid
Steering angle sensor is sending invalid 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 how far you've turned the steering wheel. If it's broken or gives the wrong numbers, the vehicle’s stability control won’t work properly, possibly making it harder to drive straight.
What the computer is actually seeing
The computer expects to see a steady signal from the steering angle sensor in degrees as you turn the wheel. If it jumps around or shows unrealistic values (like -999 or 999), that's a problem.
What a healthy reading looks like
Steering angle should vary from -540 to +540 degrees with a smooth transition; normally around 0 degrees when the wheel is centered.
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 for any loose or damaged wiring/connectors to the steering angle sensor.
- 2Verify that the steering angle sensor is securely mounted and free of obstruction.
- 3Using a scan tool, check the live data for the steering angle sensor; it should change steadily with wheel movement.
- 4Inspect the steering angle sensor settings for any calibration errors, and recalibrate if necessary.
Common causes
- Faulty steering angle sensor
- Wiring or connector issue
- Calibration loss
- Faulty steering control module

Frequently asked questions
Is it safe to drive with this code active?
It's drivable but fix it soon as stability control may be disabled.
Will this code come back after repairs?
If the underlying issue is fixed, it should stay clear; check the wiring and sensor.
Why does this code show up when I have other steering issues?
Often, steering issues can affect the sensor, or it might be a symptom of a larger problem.
