Steering Angle Sensor Signal Performance
The steering angle sensor is providing an invalid signal to the powertrain control module.
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 computer isn't getting a correct reading from the steering angle sensor, usually because of a wiring problem or the sensor itself is faulty.
What the computer is actually seeing
The powertrain control module expects a voltage signal from the steering angle sensor, typically between 0.5V and 4.5V, that should change as the steering wheel turns.
What a healthy reading looks like
Steering angle sensor voltage should be between 0.5V (full left) and 4.5V (full right).
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 connectors for damage or corrosion. Fix any issues found.
- 2Use a multimeter to test the voltage output from the steering angle sensor. It should range from 0.5V to 4.5V as you turn the wheel left and right. If it doesn't, suspect a bad sensor.
- 3Check for software calibration issues in the vehicle's computer. Sometimes the sensor needs to be re-calibrated after repairs or during vehicle alignment.
- 4If all tests pass but the code persists, inspect other related systems like the ABS module for interference.
Common causes
- Faulty steering angle sensor
- Wiring issues between the sensor and the powertrain control module
- Corroded connectors
- Alignment or calibration issues of the sensor

Frequently asked questions
Is it safe to drive with this code?
It's generally safe, but you could experience steering assist issues or loss of traction control.
Will this code come back after clearing?
If there's a persistent issue, it will likely return. Always address the root cause.
Why does this code pair with others?
Related codes often share the same systems, like ABS or steering, which can affect multiple functions.
