Common Questions

What does C0107 mean and how does it affect my car?

The C0107 code indicates a problem with your ABS wheel speed sensor circuit. This can affect your car's braking performance, especially in slippery conditions, as the ABS system relies on accurate wheel speed data to function effectively. Ignoring this issue can lead to increased stopping distances and a higher risk of accidents.

What are the most common causes of C0107 and how much does it cost to fix?

Common causes include a faulty wheel speed sensor, damaged wiring, or issues with the ABS control module. Repair costs can range from $100 for wiring repairs to $1,000 for ABS module replacement, depending on the severity of the issue and the parts needed.

Can I drive my car with C0107 or should I stop immediately?

While you may still be able to drive your car with the C0107 code, it is not recommended. The ABS system may not function correctly, especially in emergency braking situations, leading to potential safety risks. It's best to have it checked by a professional as soon as possible.

How can I diagnose C0107 myself using GeekOBD APP?

To diagnose C0107 using the GeekOBD APP, connect the app to your vehicle’s OBD2 port, run a scan for trouble codes, and review the freeze frame data. Pay close attention to the wheel speed readings to determine if they are erratic or flatlined, indicating a potential problem with the sensor or wiring.

What vehicles are most commonly affected by C0107?

Common vehicles that experience the C0107 code include the 2014-2019 Chevrolet Silverado, 2013-2018 Ford Escape, and the 2015-2019 Honda Accord. It's worth checking for any recalls or Technical Service Bulletins (TSBs) related to the ABS system for these models.

How can I prevent C0107 from happening again?

Regular maintenance of your vehicle’s braking system can help prevent the recurrence of the C0107 code. This includes checking the wheel speed sensors for damage, ensuring wiring is intact, and keeping the ABS system clean. Consider periodic diagnostics using the GeekOBD APP to catch potential issues early.

What is C0107?

The Diagnostic Trouble Code (DTC) C0107 indicates a malfunction in the Anti-lock Braking System (ABS) wheel speed sensor circuit. This code is commonly triggered when the ABS control module detects an issue with the signal from the wheel speed sensor, which is crucial for maintaining optimal braking performance and vehicle stability. The wheel speed sensor monitors the rotational speed of each wheel and sends this information to the ABS module. If the sensor fails, or if there is a wiring issue, it can lead to improper functioning of the ABS system, which could increase the risk of skidding or losing control during braking, particularly in slippery conditions. Vehicles like the 2014-2019 Chevrolet Silverado, 2013-2018 Ford Escape, and 2015-2019 Honda Accord often experience this issue. If you encounter this code, it’s essential to address it promptly, as ignoring it can lead to further complications in the braking system, potentially putting you and others at risk on the road.

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

Symptoms

Common symptoms when C0107 is present:

  • The ABS warning light illuminates on the dashboard, indicating a system malfunction.
  • The brake pedal feels soft or unresponsive, affecting the overall braking performance.
  • Increased stopping distance, particularly in wet or slippery conditions, potentially due to the ABS not engaging properly.
  • The traction control light may also activate, indicating issues with vehicle stability.
  • Unusual noises may occur during braking, such as grinding or squealing, signaling potential brake system issues.

Possible Causes

Most common causes of C0107 (ordered by frequency):

  1. The most common cause of the C0107 code is a faulty wheel speed sensor, which has a likelihood of around 60%. This can be due to physical damage or wear over time.
  2. Another frequent cause is damaged wiring or loose connections in the ABS system, which can occur due to corrosion or wear. This is about a 25% likelihood.
  3. Improper installation of brake components can lead to sensor misalignment, causing intermittent signals. Regular checks can help prevent this issue.
  4. Less commonly, a malfunctioning ABS control module can trigger this code, although it's less frequent, occurring in about 10% of cases.
  5. Rarely, software glitches in the vehicle’s electronic control unit (ECU) can also trigger the C0107 code. Keeping software updated can mitigate this risk.
