Common Questions

What does C0136 mean and how does it affect my car?

The C0136 code indicates a problem with your ABS wheel speed sensor. This is crucial for your vehicle's safety as it helps prevent wheel lock-up during emergency braking. Without it functioning properly, your braking distance can increase, and you may feel like your brakes are not responding as they should.

What are the most common causes of C0136 and how much does it cost to fix?

The most common cause of C0136 is a faulty wheel speed sensor, often costing between $100 and $300 to replace. Other causes include wiring issues and ABS module failures, which can be more expensive. Expect repair costs to range from $50 for simple wiring repairs to over $1200 for module replacements.

Can I drive my car with C0136 or should I stop immediately?

It's not advisable to drive with the C0136 code active. The issue affects your ABS, and you may experience longer stopping distances or decreased stability during hard braking. It's best to have it diagnosed and repaired before driving further.

How can I diagnose C0136 myself using GeekOBD APP?

Using the GeekOBD APP, start by scanning for diagnostic codes. The app will provide you with detailed information about the C0136 code and any related codes. You can use the freeze-frame data to see when the fault occurred and check the live data to assess the wheel speed sensor's performance.

What vehicles are most commonly affected by C0136?

Common vehicles affected by the C0136 code include the 2012-2018 Ford Focus, 2013-2017 Chevrolet Malibu, and 2015 Honda Accord. These models often experience ABS sensor issues, and it's advisable to check for any recalls or technical service bulletins (TSBs) related to the ABS system.

How can I prevent C0136 from happening again?

To prevent the C0136 code from recurring, ensure regular maintenance checks on your vehicle’s brake system, including the ABS. Keeping wiring connections clean and undamaged, and promptly addressing any warning lights can help prolong the life of your ABS components.

What is C0136?

The diagnostic trouble code (DTC) C0136 indicates a malfunction related to the Anti-lock Braking System (ABS), specifically involving the wheel speed sensor. This code often occurs when the ABS control module detects an inconsistency or failure in the readings from the wheel speed sensor, which is critical for ensuring the proper functioning of the ABS. The wheel speed sensor monitors the rotation speed of each wheel and sends this information to the ABS module to prevent wheel lock-up during braking. If the sensor is faulty, it can lead to reduced braking efficiency, increased stopping distances, and even complete failure of the ABS. In practical terms, this means a driver might experience the ABS warning light illuminating on the dashboard and potential issues with vehicle stability during hard braking. It's crucial for vehicle safety to address this issue promptly; ignoring it can lead to further complications, such as brake system failure or increased wear on brake components. Understanding this code is vital for vehicle owners, particularly those with models like the 2015 Honda Accord or 2016 Toyota Camry, which are known to experience this issue.

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

Symptoms

Common symptoms when C0136 is present:

  • The ABS warning light is illuminated on the dashboard, indicating a malfunction in the system.
  • The brake pedal may feel unusually stiff or soft, affecting braking performance and driver confidence.
  • During hard braking, the vehicle may skid or exhibit reduced control, especially on slick surfaces.
  • You might notice traction control issues where the system fails to engage or disengage properly.
  • Increased stopping distances could be evident, as the ABS may not activate when necessary.

Possible Causes

Most common causes of C0136 (ordered by frequency):

  1. The most common cause is a faulty wheel speed sensor, which accounts for about 60% of C0136 cases. This can happen due to wear and tear, exposure to moisture, or damage from road debris.
  2. A damaged wiring harness or corroded connector can also trigger this code; these issues are often overlooked during routine inspections.
  3. Another potential cause is a malfunctioning ABS control module, which can be costly and complex to diagnose. Preventive maintenance can help avoid this.
  4. Less common causes include physical damage to the ABS tone ring, which can disrupt the sensor's ability to read wheel speed accurately.
  5. In rare cases, software issues within the ABS module can lead to false readings and trigger the C0136 code.
