C0063 — Yaw Rate Sensor

C0063 points to the yaw-rate sensing function but does not, alone, prove a failed sensor. In Stellantis bulletin 08-007-23, C0063-29 denotes an invalid yaw-rate signal on specified 2022 Jeep Compass vehicles; ABS software can be implicated and stability-control or electric-parking-brake warnings may illuminate. Only VIN-qualified vehicles should follow that bulletin's ABS reprogramming path; other makes require their own diagnostic tree.

Affected system: Chassis motion sensing and stability control

Symptoms

• ABS, traction-control, stability-control, steering, or tire-pressure warning light
• ABS or stability intervention may be unavailable
• Speedometer or steering behavior may be abnormal
• Normal base braking may remain but driver-assistance functions can be reduced

Possible causes

• Wheel-speed sensor, encoder ring, steering-angle sensor, or acceleration sensor fault
• Damaged harness, connector corrosion, poor ground, or incorrect supply voltage
• Incorrect sensor calibration or chassis-module configuration
• Brake, bearing, tire, steering, or suspension mechanical problem

What to check

• Read codes from ABS, stability, steering, suspension, and powertrain modules
• Save freeze-frame and failure-type information
• Inspect the affected corner or sensor and compare live values side by side
• Perform circuit and mechanical tests from vehicle service information
• Calibrate sensors if required and verify the repair on a safe road test
• Compare all wheel speeds and chassis sensor values during a controlled test
• Inspect sensor wiring, encoder rings, bearings, tires, and connectors
• Verify power, ground, signal, and required sensor calibration

Also written as: C0063-00, C006300, CO063 (some scan tools add the fault-type byte, e.g. -00).
