C0230
Stability Control Steering Wheel Position Sensor Circuit
Severesensor
Overview
The C0230 diagnostic trouble code means the chassis control module has identified a stability control steering wheel position sensor circuit problem. This code relates to a chassis sensor providing incorrect or missing data to the control module. Chassis sensor issues can affect braking, steering, and stability control performance.
Symptoms
- Incorrect sensor data shown on scan tool
- Check Engine Light (MIL) illuminated
- Idle speed fluctuations
- Erratic gauge readings on dashboard
Common Causes
- Water intrusion in sensor connector
- Corroded or damaged sensor connector
- Faulty PCM/ECM not reading sensor correctly
- Physical damage to sensor
Diagnosis Steps
- 1Connect an OBD-II scanner and read all stored trouble codes and freeze frame data
- 2Locate the specific sensor referenced by the code
- 3Inspect the sensor connector for corrosion, damage, or loose pins
- 4Test the sensor output using a multimeter or scan tool live data
- 5Check the wiring between the sensor and the PCM for opens or shorts
