Steering Angle Sensor Range/Performance Problem
The steering angle sensor is reporting values outside the expected range.
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, which detects how far the steering wheel is turned, is sending readings that the vehicle's computer considers out of normal range.
What the computer is actually seeing
The computer expects the steering angle to be between -540° and +540° during operation. If it receives a signal that is higher or lower than this, it triggers the code.
What a healthy reading looks like
Steering angle should typically read between -540° and +540°. The sensor output voltage under normal operation should be around 0.5 to 4.5 volts, corresponding with the angle range.
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.
- 1Inspect wiring and connectors related to the steering angle sensor for damage or loose connections. Ensure there are no shorts or opens.
- 2Check the physical condition of the steering angle sensor — look for any visible damage or debris obstructing it.
- 3Use a scan tool to view live data. Observe the steering angle sensor output as you manually turn the steering wheel. It should reflect smooth and accurate changes in angle without erratic jumps.
- 4If the sensor readings are erratic or nonexistent, consider replacing the steering angle sensor. If readings are consistent but outside expected range, check for steering column alignment and recalibration.
Common causes
- Faulty steering angle sensor
- Wiring issues (shorts/cuts)
- Connector corrosion or damage
- Steering column misalignment
- Calibration issues after repairs
Typical repair cost
$$$ (depending on the sensor and labor costs)

Frequently asked questions
Is it safe to drive with this code active?
It's drivable, but be cautious as it may affect traction control and stability systems.
Will this code come back after clearing it?
If the underlying issue isn't fixed, yes, the code will likely return.
Why do I see this code along with ABS codes?
Steering angle sensors are often used in conjunction with ABS systems for stability control, so issues with one can affect the other.
