Common Questions

What does C0267 mean and how does it affect my car?

The C0267 code indicates a malfunction in the anti-lock brake system, which can lead to increased stopping distances and compromised braking effectiveness. This code signals that the ABS is not functioning correctly, potentially putting your safety at risk. It's vital to address this code promptly to maintain optimal braking performance.

What are the most common causes of C0267 and how much does it cost to fix?

The most common cause of C0267 is a faulty wheel speed sensor, which can be replaced for around $150 to $300. Damaged wiring or connectors can also lead to this code, costing between $100 and $200 to repair. In rare cases, the ABS control module may need replacement, which can range from $400 to $800.

Can I drive my car with C0267 or should I stop immediately?

While you may be able to drive with the C0267 code, it's highly advisable to stop and have your vehicle checked. Compromised braking performance can pose serious safety risks, particularly in emergency situations. Ignoring this code could lead to accidents or further damage.

How can I diagnose C0267 myself using GeekOBD APP?

To diagnose C0267 using the GeekOBD APP, first connect the device to your vehicle's OBD2 port. Use the app to retrieve trouble codes and check for any additional codes that may provide context. Analyze the freeze frame data to understand the conditions under which the code was triggered, and perform component tests as needed.

What vehicles are most commonly affected by C0267?

The C0267 code is frequently reported in vehicles like the 2010-2016 Chevrolet Equinox and GMC Terrain. Other models from GM, particularly during this production range, may also experience this issue. It’s important to stay updated on any recalls or Technical Service Bulletins (TSBs) related to braking systems.

How can I prevent C0267 from happening again?

To prevent the C0267 code from recurring, ensure regular maintenance of your braking system. This includes periodic inspections of wiring and connections, replacing worn components promptly, and using high-quality brake fluids. Additionally, using diagnostic tools like the GeekOBD APP can help catch issues early before they escalate.

What is C0267?

The DTC C0267 code indicates a specific malfunction within the vehicle's brake system, particularly related to the Anti-lock Braking System (ABS). This code typically appears when the ABS control module detects an issue that could affect the braking performance. For vehicles like the 2010-2016 Chevrolet Equinox or GMC Terrain, a C0267 code can lead to problems such as increased stopping distances or a lack of brake effectiveness, which could be dangerous while driving. The code often signals issues with components such as wheel speed sensors, wiring harnesses, or the ABS control module itself. It's essential to understand that while the vehicle may still be operable, the compromised braking system poses a significant safety risk. Ignoring the C0267 code can lead to more severe brake system failures, potentially resulting in costly repairs and putting the driver and passengers at risk. Regular diagnostics using tools like the GeekOBD APP can help identify issues early, allowing for timely repairs and maintaining vehicle safety.

Symptoms

Common symptoms when C0267 is present:

  • Check engine light stays on constantly, indicating an ongoing issue with the ABS.
  • Braking feels less responsive, with a noticeable delay when applying pressure to the brake pedal.
  • ABS warning light illuminates on the dashboard, indicating a malfunction.
  • Increased stopping distance, which may be felt during emergency braking situations.
  • Unusual noises or vibrations when braking, suggesting component malfunction.

Possible Causes

Most common causes of C0267 (ordered by frequency):

  1. Faulty wheel speed sensor is the most common cause, occurring in about 40% of cases. This sensor measures the speed of the wheel and sends this information to the ABS module. If it fails, the ABS may not function correctly.
  2. Damaged wiring or connectors account for about 30% of C0267 occurrences. Corroded or frayed wires can disrupt signals to and from the ABS control module.
  3. Issues with the ABS control module itself, which can malfunction due to internal faults or software errors. This is less common but can lead to major repair costs.
  4. Brake fluid leaks or low fluid levels, which may cause performance issues but are less frequently the direct cause of the C0267 code.
  5. Rarely, a malfunctioning brake pedal switch can trigger this code, affecting the system's ability to detect when brakes are applied.
