Faulty Steering Angle Sensor Signal
The steering angle sensor signal is out of 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)
Your steering angle sensor is telling the computer that your steering wheel is at an angle it shouldn't be under normal conditions, which can mess with traction control or stability systems.
What the computer is actually seeing
The computer expects the steering angle to be between -90 and +90 degrees when stationary, but it's reading values outside this range, often due to a fault in the sensor or wiring.
What a healthy reading looks like
Steering angle should be within -90 to +90 degrees; expected voltage from the sensor could be around 0.5 to 4.5 volts depending on 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 wiring and connectors to the steering angle sensor for damage or corrosion. If they look good, move to step 2.
- 22. Disconnect the steering angle sensor and measure the voltage at the connector while turning the steering wheel. It should vary between 0.5 to 4.5 volts. If not, replace the sensor.
- 33. If voltage is correct, reconnect the sensor and scan for codes. Perform a steering angle sensor calibration if recommended. Check if the code returns after calibration.
- 44. If still present, inspect the power and ground circuits to the sensor for continuity. Repair any faults found.
Common causes
- Faulty steering angle sensor
- Damaged wiring or connectors
- Calibration issues after service work
- Poor battery ground connections

Frequently asked questions
Is it safe to drive with this code?
It's drivable but be aware that traction control and stability features may not work properly, impacting safety.
Will this code come back after clearing it?
If the underlying issue isn't fixed, yes, the code will likely return.
Why might this pair with other codes?
Multiple codes can indicate a systemic issue with the vehicle's stability systems.
