Invalid Data Received From Steering Angle Sensor
There's a problem with the steering angle sensor 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 tells the car's computer how much and in which direction you're turning the steering wheel. If it's malfunctioning, the computer may get incorrect information about the steering position, affecting things like stability control.
What the computer is actually seeing
The computer expects a signal voltage from the steering angle sensor between 0.5V (left turn) and 4.5V (right turn), primarily around 2.5V at center position. If it detects a voltage outside this range or no signal, it triggers this code.
What a healthy reading looks like
Steering angle sensor output should be between 0.5V and 4.5V, centered around 2.5V when at straight-ahead position.
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 connectors at the steering angle sensor for damage or corrosion. Repair as needed. Decision: If wiring is damaged, fix it and retest; if not, proceed to step 2.
- 22. Measure the voltage output from the steering angle sensor while rotating the steering wheel slowly from left to right. Expected values are between 0.5V to 4.5V. Decision: If voltage is outside the range, replace the sensor; if in range, proceed to step 3.
- 33. Verify if the steering angle sensor needs calibration by using a scan tool. If calibration is needed, perform the calibration procedure. Decision: If calibration remedies the issue, you're done; if not, further inspect for underlying faults.
Common causes
- Faulty steering angle sensor
- Wiring issues or bad connectors
- Calibration not done after steering component repair
- Steering rack or column damage

Frequently asked questions
Is it safe to drive with this code active?
It's not dangerous in the short term, but stability control may not function correctly, so fix it soon.
Will this code come back after clearing?
If the underlying issue isn't fixed, yes, it will likely return.
Why does this code pair with other steering codes?
They're often related to the steering angle sensor or its circuit, which affects multiple vehicle dynamics.
