Common Questions

What does C0106 mean and how does it affect my car?

The C0106 code indicates a problem with the wheel speed sensor circuit. This can affect your ABS and traction control systems, potentially leading to unsafe driving conditions. Ignoring this code may cause decreased braking effectiveness and could lead to accidents.

What are the most common causes of C0106 and how much does it cost to fix?

Typical causes of C0106 include a faulty wheel speed sensor, damaged wiring, or a malfunctioning ABS control module. Repair costs can range from $50 for wiring repairs to $800 for ABS module replacement, depending on the issue.

Can I drive my car with C0106 or should I stop immediately?

While it may be possible to drive your vehicle with the C0106 code, it is not advisable due to safety concerns. The ABS may be disabled, increasing the risk of losing control during emergency braking.

How can I diagnose C0106 myself using GeekOBD APP?

Using the GeekOBD APP, you can perform a quick scan of your vehicle to check for the C0106 code. The app will provide you with freeze frame data, helping you understand the context of the issue. Follow the app's prompts for further diagnostics.

What vehicles are most commonly affected by C0106?

The C0106 code is commonly found in various General Motors vehicles, such as the Chevrolet Silverado and GMC Sierra from 2005 to 2018. Other models may also experience this issue, particularly those with ABS systems.

How can I prevent C0106 from happening again?

Regular vehicle maintenance, including inspections of the ABS system and wheel speed sensors, can help prevent C0106. Keeping the wiring clean and free from corrosion can also reduce the chances of this code appearing.

What is C0106?

The DTC C0106 code indicates a problem with the wheel speed sensor circuit, particularly a performance or range issue. This diagnostic trouble code is prevalent in various vehicles, especially those from General Motors, such as the Chevrolet Silverado and GMC Sierra, produced between 2005 and 2018. A wheel speed sensor is crucial for the vehicle's ABS (Anti-lock Braking System) and traction control systems, which help prevent skidding and maintain traction on slippery surfaces. When the C0106 code triggers, it typically means that the powertrain control module (PCM) has detected an anomaly in the signal from one of the wheel speed sensors. This could manifest as an incorrect voltage reading, or the sensor may be entirely non-functional. If this issue remains unaddressed, it can lead to decreased braking effectiveness and compromised vehicle safety. Car owners should not ignore this code, as it could escalate into more severe problems affecting the vehicle's handling and stability. To ensure safety, immediate diagnostics and repair are recommended. Regular maintenance and checks on the ABS system can also help prevent this code from appearing in the future.

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

Symptoms

Common symptoms when C0106 is present:

  • The ABS warning light remains illuminated on the dashboard, indicating an issue with the braking system.
  • Poor vehicle handling, especially during wet or slippery conditions, leading to loss of traction.
  • Inconsistent speedometer readings, which may fluctuate or become entirely unresponsive.
  • The traction control system may disable itself, leading to increased wheel spin during acceleration.
  • Unexpected braking behavior, such as the ABS engaging in normal driving conditions.

Possible Causes

Most common causes of C0106 (ordered by frequency):

  1. The most common cause of C0106 is a faulty wheel speed sensor, with a likelihood of about 60%. Sensors can fail due to wear and tear or exposure to moisture and debris.
  2. Another frequent cause is damaged wiring or connectors in the wheel speed sensor circuit, estimated at 25%. Corrosion or loose connections can disrupt the signal.
  3. Additionally, issues in the ABS control module can also trigger this code, with a lower likelihood of around 10%. Regular checks on the module can help prevent this.
  4. Less common but serious causes include a malfunctioning PCM, which could lead to incorrect readings and ultimately affect vehicle safety.
  5. In rare cases, the issue can stem from a malfunctioning brake system, particularly in older vehicles, leading to erratic sensor performance.
