Causes
- Yaw rate (MEMS) sensor internal failure
- Damaged wiring harness, broken wires or chafed insulation to the sensor
- Poor connector contact, corrosion or bent pins at the sensor connector
- Loss of sensor supply voltage or ground
- Faulty CAN/LIN communication or module receiving the sensor data
- Incorrect sensor mounting or physical damage to sensor/vehicle structure
Symptoms
- ABS/ESC/traction control warning lamp illuminated
- Stability control or traction control disabled
- Unresponsive or inconsistent stability intervention during cornering
- Diagnostic trouble code C0063 stored in ABS/ESC module
- Possible limp or reduced vehicle dynamic control
What to check
- Read all stored and pending DTCs and freeze-frame data with a capable scan tool
- Confirm whether code is current, intermittent or historic; check event counters
- Visually inspect sensor and harness for damage, water ingress, corrosion or loose connectors
- Perform wiggle test of harness/connectors while monitoring live yaw rate signal
- Check vehicle battery voltage and charging system for proper supply
- Scan CAN bus for related communication errors or U-codes
Signal parameters
- Sensor supply: typically 5 V reference (varies by model) and ground
- Output: angular rate signal (degrees/sec) or analog/digital voltage; many sensors idle near mid-rail (≈2.5 V) at 0°/s
- Sensitivity: small voltage change per deg/s (manufacturer-specific; check service data)
- Signal behavior: smooth change with controlled yaw; noisy, frozen or out-of-range values indicate fault
- Communication: some modules report yaw rate over CAN/LIN — message ID and scaling are vehicle-specific
Diagnostic algorithm
- Use a factory-level scan tool to record C0063, other related codes and freeze frame data; note mileage/time.
- Check for additional communication (U) codes; if bus is inactive, repair CAN/LIN first.
- Visually inspect the yaw rate sensor, bracket and wiring harness for damage, moisture or corrosion.
- With ignition on, back-probe the sensor connector and verify reference voltage and ground per service data.
- Monitor live yaw rate signal with scanner or oscilloscope; observe sensor output at rest and during a controlled low-speed test (or on a lift with wheels turned per service instructions).
- Perform a wiggle test of harness/connectors while watching live data for intermittent faults.
- If supply/ground/comms OK but signal is out of range or absent, consult wiring diagrams and check continuity/resistance of sensor circuits.
- If wiring and module communications are good, replace the sensor with a OEM or approved replacement.
- After replacement, clear codes and perform any required sensor alignment/calibration or road test procedures with the service tool.
- Re-scan to confirm the fault does not return and verify ESC/ABS functions are restored.
Likely causes
- Connector corrosion or pin damage at the sensor
- Wiring open, short to ground or short to battery in the sensor circuit
- Sensor internal electronics failure (common with water ingress or impact)
- Loss of 5 V reference or ground to the sensor from module
- CAN bus message missing or corrupted (module comms fault)
Fault status
Status
Active/Stored: Yaw rate sensor fault detected (C0063). Sensor signal missing, invalid or out of range. ESC/traction control may be disabled until fault cleared and fault cause repaired and sensor recalibrated.
Repair difficulty: Medium
Diagnostic time: 1.0 - 2.5 hours
