Common Questions

What does C0167 mean and how does it affect my car?

The C0167 code signifies a malfunction in your vehicle's traction control system, which is designed to help maintain grip on slippery surfaces. If this system is compromised, you might experience traction issues, especially during adverse weather conditions, leading to potentially hazardous driving situations.

What are the most common causes of C0167 and how much does it cost to fix?

Common causes of C0167 include faulty wheel speed sensors, damaged wiring, or issues with the traction control module. Repair costs can range from $100 for wiring repairs to over $800 for module replacements, depending on the specific issue.

Can I drive my car with C0167 or should I stop immediately?

While it's possible to drive with the C0167 code, it's not advisable. The traction control system plays a crucial role in vehicle safety, especially in slippery conditions. If you notice any abnormal handling or warning lights, it's best to have your vehicle inspected as soon as possible.

How can I diagnose C0167 myself using GeekOBD APP?

Using the GeekOBD APP, connect to your vehicle's OBD2 port to retrieve diagnostic trouble codes, including C0167. The app provides freeze frame data and historical error codes, helping you understand when the issue occurred and under what conditions, which is vital for accurate troubleshooting.

What vehicles are most commonly affected by C0167?

The C0167 code is frequently reported in vehicles like the 2006-2010 Chevrolet Impala, 2012-2015 GMC Terrain, and many other GM models. If you own any of these vehicles, be particularly vigilant for traction-related issues, especially in wet or icy conditions.

How can I prevent C0167 from happening again?

To prevent the C0167 code from recurring, ensure regular maintenance of your vehicle's brake and traction control systems. Keep an eye on warning lights, and consider periodic inspections of wheel speed sensors and wiring, especially if you drive in harsh weather conditions.

What is C0167?

The diagnostic trouble code (DTC) C0167 indicates a fault in the traction control system (TCS) of your vehicle, which is crucial for maintaining stability and control, especially in slippery conditions. This code is often triggered by issues within the TCS sensors, wiring, or control module. When C0167 is present, the vehicle may experience reduced traction, making it more challenging to drive in adverse weather. Commonly seen in vehicles like the 2006-2010 Chevrolet Impala and 2012-2015 GMC Terrain, the implications of C0167 can lead to the traction control light illuminating on your dashboard, and in some cases, the anti-lock braking system (ABS) may also be affected. Addressing this code promptly is essential for safety, as it can impact your vehicle's handling during critical driving conditions. If ignored, you might also face increased wear on tires and other drivetrain components due to erratic traction control engagement. To resolve the issue, it is important to conduct a thorough diagnostic evaluation, as multiple factors can contribute to the C0167 code.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C0167 is present:

The traction control warning light on the dashboard illuminates, indicating a potential problem with the system.
Drivers may notice the vehicle's handling feels unstable, particularly during acceleration on wet or icy roads.
You might experience increased tire slippage when starting from a stop, especially on slippery surfaces.
In some cases, the ABS light may also activate, suggesting a more extensive issue with the braking system.
Unusual sounds or vibrations may occur when the traction control system attempts to engage.

Possible Causes

Most common causes of C0167 (ordered by frequency):

{'description': 'The most common cause of the C0167 code is a faulty wheel speed sensor, which occurs in approximately 45% of cases. This sensor monitors the speed of each wheel and communicates with the traction control module. If it fails or sends erratic signals, the TCS may not function properly.', 'likelihood': '45%'}
{'description': 'Another frequent cause is damaged wiring or connectors in the traction control system, accounting for about 30% of cases. Corrosion or wear can disrupt the electrical signals, leading to faults.', 'likelihood': '30%'}
{'description': 'Issues with the traction control module itself can lead to the C0167 code, representing around 15% of cases. This module processes input from various sensors and can malfunction due to software errors or internal component failures.', 'likelihood': '15%'}
{'description': 'Less commonly, a malfunctioning ABS module can trigger this code, affecting TCS operation. Regular checks of the ABS system can help prevent this issue.', 'likelihood': '5%'}
{'description': 'Rarely, a complete brake system failure can lead to C0167. This is a serious issue that requires immediate attention. Regular brake maintenance helps prevent such failures.', 'likelihood': '5%'}

C0167 Repair Costs

Cost Breakdown by Repair Type

Wheel Speed Sensor Replacement

Replacing a faulty wheel speed sensor is often necessary to resolve C0167. This repair typically involves accessing the sensor located near the wheel hub.

Total: $150 - $300
Success rate: 90%

Wiring Repair

Repairing damaged wiring or connectors in the traction control system can eliminate faults causing the C0167 code. This may involve splicing or replacing wiring harnesses.

Total: $100 - $250
Success rate: 80%

Traction Control Module Replacement

In cases where the module itself is at fault, replacing it could be necessary. This is a more complex repair.

Total: $500 - $800
Success rate: 85%
