Common Questions

What does C0135 mean and how does it affect my car?

DTC C0135 indicates a malfunction within the traction control system, often linked to wheel speed sensors. This can lead to decreased vehicle stability, particularly on slippery roads, resulting in possible loss of control. It’s essential to address this code promptly to ensure your vehicle operates safely.

What are the most common causes of C0135 and how much does it cost to fix?

Common causes of C0135 include faulty wheel speed sensors, damaged wiring, or a malfunctioning traction control module. Repair costs can range from $50 for wiring repairs to $600 for a module replacement, depending on the specific issue.

Can I drive my car with C0135 or should I stop immediately?

While it's possible to drive with a C0135 code, doing so is not advisable due to the potential loss of traction and control, especially in adverse weather conditions. It's recommended to seek a professional diagnosis as soon as possible.

How can I diagnose C0135 myself using GeekOBD APP?

To diagnose C0135 with the GeekOBD APP, start by connecting the app to your vehicle’s OBD2 port. Retrieve the DTC and check the freeze frame data for conditions at the time of the fault. Use the app’s diagnostic tools to test the wheel speed sensors and monitor their output while driving.

What vehicles are most commonly affected by C0135?

C0135 is commonly found in vehicles like the 2014-2019 Ford F-150, 2016-2018 Chevrolet Silverado, and various models from Toyota and Honda. Always check for any recalls or technical service bulletins related to the traction control system.

How can I prevent C0135 from happening again?

Regular maintenance can help prevent C0135 from reoccurring. Ensure your vehicle's wiring and sensors are inspected during routine services, and replace any worn components promptly. Using protective measures against road debris can also minimize damage.

What is C0135?

DTC C0135 indicates a problem with the traction control system, particularly related to the input from the wheel speed sensors. When this code is triggered, it typically means that the traction control module has detected an abnormal signal or a failure in the associated wiring or components. This can lead to the traction control system being disabled, affecting vehicle stability during acceleration and cornering. For instance, in 2014-2019 Ford F-150 models, this code might be triggered due to a failing wheel speed sensor or damaged wiring harness. When the traction control system is not functioning properly, drivers may experience issues like spinning tires on wet or slippery surfaces, failing to maintain traction, or even unexpected loss of vehicle control. Ignoring this issue can lead to further complications, such as increased wear on tires and brake components due to improper traction management. Therefore, it's critical for vehicle owners experiencing symptoms related to DTC C0135 to seek a professional diagnosis to ensure safety on the road.

Symptoms

Common symptoms when C0135 is present:

  • The traction control warning light illuminates on the dashboard, indicating a malfunction.
  • Drivers may notice the vehicle spinning tires excessively in slippery conditions, leading to loss of control.
  • There may be a noticeable decrease in acceleration, especially on wet or uneven surfaces.
  • The ABS light may also trigger, suggesting a correlation with the traction control issue.
  • Unusual noises, such as grinding or clicking, may occur during acceleration or when turning.

Possible Causes

Most common causes of C0135 (ordered by frequency):

  1. The most common cause of DTC C0135 is a faulty wheel speed sensor, with a likelihood of about 60%. These sensors can wear out over time or be damaged due to road debris.
  2. Another possible cause is damaged wiring or connections, which can occur due to corrosion or physical wear, accounting for 25% of cases.
  3. A malfunctioning traction control module may also trigger this code, though it is less common, representing around 10% of issues.
  4. In rare cases, a failed ABS pump may lead to this code, although it is not frequently encountered.
  5. Finally, low battery voltage can affect the traction control system's operation, which is a less common but possible cause.
