Steering Angle Sensor Circuit Range/Performance Problem
This code indicates a performance problem with the steering angle sensor circuit.
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 and fast the steering wheel is turned. If it sends incorrect signals, the vehicle's systems may struggle to know the steering position, affecting handling and stability.
What the computer is actually seeing
The computer expects the steering angle sensor to provide a specific voltage based on the angle of the steering wheel. If it detects a voltage outside the expected range (typically 0.5V to 4.5V), it triggers this code.
What a healthy reading looks like
0.5V to 4.5V corresponding to -90 to +90 degrees steering input.
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. Inspect the steering angle sensor connector and wiring for damage or corrosion. Decision: If damaged, repair or replace; if intact, proceed to step 2.
- 22. Use a scanner to read the current voltage output from the steering angle sensor while turning the steering wheel. Decision: If voltage is within expected range (0.5V to 4.5V), proceed to step 3; if outside this range, replace the sensor.
- 33. Check the vehicle's calibration data for the steering angle sensor. Decision: If calibration is incorrect, recalibrate the sensor; if correct, further investigate the power supply and ground for the sensor.
Common causes
- Faulty steering angle sensor
- Wiring issues or open circuits
- Faulty steering column
- Poor connections or corrosion at the connector
Typical repair cost
$100 - $400

Frequently asked questions
Is it safe to drive with this code active?
You can still drive the vehicle, but steering response may be compromised, especially in slippery conditions.
Will this problem come back after resetting the code?
If the underlying issue isn't fixed, the code will likely return.
Why does this code sometimes pair with wheel speed sensor codes?
Both systems rely on accurate measurements for stability control; a fault in one may affect the other.
