U0126 Code: Lost Communication with Steering Angle Sensor — Causes & Fix
U0126 means lost communication with the steering angle sensor module — the sensor that tells stability control which way the wheel is turned.
- Applies to
- All OBD-II vehicles (any make or model)
- Est. repair cost
- $50 – $700
- Time to fix
- 1–4 hours
What it means
Causes include a failed steering angle sensor/clockspring, CAN wiring faults, or a connector problem. U0126 is a generic OBD-II network/communication ("U") code defined in the SAE J2012 standard, so it applies to virtually any modern OBD-II vehicle regardless of make. These faults usually point to the vehicle's data bus (often CAN) or a module that has dropped off the network. Fix the wiring/module fault, then clear the code with a scan tool.
Symptoms
- Stability/traction and ABS lights on
- Stability control disabled
- Possible steering-related warnings

Frequently asked questions
Why is my stability control off with U0126?
Stability control needs the steering angle to work. If that data is lost, the system disables itself until the sensor communication is restored.
