C0063: Yaw Rate Sensor (Subfault)

What it means

This code identifies a fault associated with the yaw rate sensor. The specific failure depends on the diagnostic subtype.

How it works

The yaw rate sensor measures how quickly the vehicle rotates around its vertical axis, giving the stability-control module information about turning and skidding. C0063 identifies a fault associated with that sensor; its subtype determines the specific failure condition.

Common causes

Most likely first.

1. Faulty yaw rate sensor
2. Damaged or loose sensor connector
3. Open or shorted wiring
4. Sensor misalignment or lost calibration

Symptoms

• ABS or stability control warning light
• Traction control warning light
• Stability control may be limited or disabled
• Unexpected stability control intervention

How to diagnose it

1. Read the stability-control module's freeze-frame and subtype details, then check live yaw-rate data with the vehicle stationary and during a gentle, safe turn.
2. Inspect the yaw sensor connector and wiring for looseness, corrosion, damaged pins, or chafing.
3. Check that the sensor is securely mounted in its specified orientation and has not been disturbed during repairs.
4. Test the sensor circuit and output according to the manufacturer's procedure and specification.
5. If electrical checks pass, verify whether the subtype calls for yaw sensor calibration or replacement.

Common fixes

• Reconnect a loose yaw rate sensor connector.
• Repair damaged wiring or connector terminals in the sensor circuit.
• Secure the sensor in its specified position and perform required calibration.
• Replace the yaw rate sensor if tests confirm an internal fault.

Can I keep driving?

Stability control may be limited or may intervene unexpectedly, although basic braking may remain normal. Drive smoothly, avoid slippery roads and abrupt turns, and stop if the system applies braking unexpectedly.
