C0063 — Yaw Rate Sensor (Subfault) #

The wording of this code may vary depending on the vehicle manufacturer.

• Yaw Rate Sensor (Subfault) — General (multiple OEMs)
• Yaw Rate Sensor Circuit Malfunction — GM
• Yaw Rate Sensor Signal Fault — Ford
• Yaw Rate Sensor Performance — Toyota

Summary of DTC C0063 #

The Diagnostic Trouble Code C0063 relates to a malfunction detected in the yaw rate sensor circuit, often described as a “subfault.” The yaw rate sensor is a key component in the vehicle’s stability control system, measuring the rotation rate around the vertical axis to help the Electronic Stability Control (ESC) system maintain control during turns. When this code appears, it generally means that the sensor’s signal is irregular, inconsistent, or outside expected values. A subfault typically signals an intermittent or partial issue, rather than a total failure. Prompt attention is recommended, as this can affect the vehicle’s handling and safety features.

Common Symptoms for DTC C0063 #

A vehicle registering code C0063 may exhibit a range of symptoms, some subtle and others more apparent. Most drivers will notice warnings related to stability or traction, and in some cases, changes in how the vehicle responds during sharp maneuvers. Here are the most frequent signs:

• Illuminated ESC/ESP/DSC warning light (Electronic Stability Control / Electronic Stability Program / Dynamic Stability Control)
• ABS warning light may also appear
• Loss or reduction of stability control functions
• Increased risk of skidding or fishtailing during sharp turns
• Occasional loss of traction control
• Erratic or delayed response to steering inputs

Most Likely Causes of C0063 (in Order of Frequency) #

The C0063 code is typically triggered by issues in the yaw rate sensor circuit. The root causes can range from sensor-level faults to wiring and communication errors. The most frequent causes, in order, are:

1. Faulty yaw rate sensor (sensor itself has failed or is sending irregular data)
2. Loose, corroded, or damaged wiring/connectors between the sensor and the ESC module
3. Faulty ESC/ABS control module (less common, but possible)
4. Electrical interference or ground faults
5. Sensor misalignment due to improper installation or collision

Step-by-Step Diagnostic Guide for C0063 #

Diagnosing a yaw rate sensor subfault requires methodical checks, as the problem can be hardware or wiring related. Here’s how a technician or experienced DIYer should proceed:

• Scan for all related codes: Use a diagnostic scanner to check for additional ABS or ESC-related DTCs that may help narrow down the issue.
• Inspect warning lights and dashboard indicators: Confirm which warning lights are present, and note any patterns.
• Visually examine yaw rate sensor and wiring: Locate the sensor (usually under the center console or near the transmission tunnel) and check for signs of physical damage, loose connectors, or corrosion.
• Test sensor output: Using a scan tool with live data, monitor the yaw rate sensor reading while gently rocking the car or turning the steering wheel. Look for irregular or implausible values.
• Check wiring continuity and resistance: Use a multimeter to verify wiring integrity between the sensor and control module.
• Inspect ESC/ABS module: If prior steps reveal no fault, consider module diagnostics or reprogramming per OEM procedure.
• Clear codes and test drive: After repairs, clear all codes and test drive the vehicle to ensure the fault does not return.

Possible Repairs for DTC C0063 #

Depending on the cause found during diagnosis, the following repairs are commonly performed to resolve a C0063 code:

• Replace faulty yaw rate sensor (most frequent solution)
• Repair or replace damaged wiring/connectors
• Clean and secure all electrical contacts and grounds
• Realign or reinstall the sensor if misaligned
• In rare cases, replace or reprogram the ESC/ABS control module

Is It Safe to Drive with DTC C0063? #

Driving with a C0063 code is possible but not recommended, especially in adverse weather or emergency maneuvers. The vehicle may lose stability or traction control functions, increasing the risk of skidding, oversteer, or understeer—especially on wet or slippery roads. While basic driving is often unaffected, safety systems designed to help in critical moments will be compromised. It is best to have the issue diagnosed and repaired as soon as possible.

Vehicles Most Commonly Affected by C0063 #

While C0063 can occur on any modern vehicle equipped with stability control, certain makes and models have reported this code more frequently. Typically, these include vehicles where the yaw rate sensor location is prone to moisture or vibration, or where wiring harnesses are exposed. Common examples:

• Chevrolet and GMC SUVs and trucks (GM)
• Ford Focus, Fusion, and Escape (Ford)
• Toyota Camry, Corolla, and RAV4 (Toyota)
• Volkswagen Passat and Golf (VW)
• Honda Accord and Civic (Honda)

Common Mistakes & Best Practices for C0063 #

Misdiagnoses are not uncommon with yaw rate sensor codes, as symptoms can overlap with other stability or ABS issues. To avoid wasted time and money, keep these points in mind:

• Don’t replace the sensor without testing wiring and power supply first
• Always check for water intrusion under carpets, especially after leaks or floods
• Verify that the sensor is properly aligned—improper installation can trigger faults
• Use OEM or high-quality replacement parts; cheap sensors can cause repeat failures
• Clear codes after repairs and perform a test drive to confirm resolution

Quick FAQ for C0063 #

Below are answers to common questions about this code:

• Can a C0063 code cause my ABS light to come on?
  Yes, the ABS light often illuminates when stability control systems are affected by a sensor fault.
• Do I need to recalibrate the sensor after replacement?
  In most cases, yes. OEM procedures usually require a stability control system reset or calibration using a scan tool after installing a new yaw rate sensor.
