The main causes of the C0807 code include faulty wheel speed sensors, wiring issues, and sometimes a malfunctioning ABS module. Repair costs can range from $100 for sensor replacement to $150 for wiring repairs, depending on the specific issue.

Can I drive my car with C0807 or should I stop immediately?

While it's possible to drive with the C0807 code, it's not advisable. The ABS and traction control systems may not function correctly, increasing the risk of accidents, especially in slippery conditions. It's best to have it diagnosed and repaired promptly.

How can I diagnose C0807 myself using GeekOBD APP?

To diagnose C0807 using the GeekOBD APP, connect the device to your vehicle's OBD2 port, run a full scan to retrieve codes, and analyze the freeze frame data. This will help you understand the conditions that triggered the code and guide your next steps.

What vehicles are most commonly affected by C0807?

Common vehicles affected by the C0807 code include the 2010-2015 Ford F-150, 2011-2016 Chevrolet Silverado, and 2008-2014 GMC Sierra. Check for any recalls or technical service bulletins related to the ABS system for your model.

How can I prevent C0807 from happening again?

Regular maintenance and inspections of your braking system and wheel speed sensors can help prevent C0807. Keep an eye on your ABS light and address any warning signs early to avoid larger issues down the road.

What is C0807?

DTC C0807 is a diagnostic trouble code that indicates a malfunction in the wheel speed sensor circuit. This code is prevalent in various vehicle makes, particularly in models from Ford, Chevrolet, and GMC, typically manufactured between 2005 and 2018. The wheel speed sensor plays a critical role in monitoring the speed of each wheel, providing essential data to the vehicle's anti-lock braking system (ABS) and traction control systems. When the C0807 code is triggered, it suggests that there may be an issue such as an open circuit, short circuit, or a malfunction in the sensor itself. Car owners may notice that the ABS light illuminates on the dashboard, and the braking system may behave erratically. Additionally, it can affect the stability control and traction control systems, leading to decreased vehicle safety, especially in adverse weather conditions. Ignoring this code can lead to further damage and expensive repairs down the line, making it crucial to diagnose and resolve as soon as possible. Drivers should be aware of the implications, as the functionality of the entire braking system can be compromised, resulting in potential safety hazards. Thus, addressing a C0807 code promptly is advisable for maintaining a safe driving experience.

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

Symptoms

Common symptoms when C0807 is present:

  • The ABS warning light remains illuminated, indicating a potential issue with the anti-lock braking system.
  • Unexpected changes in braking performance, such as longer stopping distances or unresponsive brakes during emergency situations.
  • Inconsistent traction control engagement, causing the system to activate at inappropriate times, especially in slippery conditions.
  • Potential decrease in fuel economy, as the vehicle may struggle to maintain optimal performance due to the sensor malfunction.

Possible Causes

Most common causes of C0807 (ordered by frequency):

  1. {'cause': 'Faulty wheel speed sensor (60% likelihood) - This is the most common reason for the C0807 code, where the sensor itself fails due to wear or damage.', 'details': 'Wheel speed sensors can wear out over time due to exposure to road debris, moisture, or extreme temperatures.'}
  2. {'cause': 'Wiring issues (25% likelihood) - Damaged, corroded, or disconnected wiring harnesses can interrupt the signal to the onboard computer.', 'technicalExplanation': 'Electrical shorts or open circuits in the wiring can prevent the signal from reaching the ABS module, triggering the DTC C0807.'}
  3. {'cause': 'Faulty ABS module (10% likelihood) - Although less common, a malfunctioning ABS control module can misinterpret signals from the wheel speed sensors.', 'preventionTips': 'Regular inspection of the ABS module and ensuring proper maintenance can help avoid this issue.'}
  4. {'cause': 'Poor connections (3% likelihood) - Loose or corroded electrical connections at the sensor or ABS module can lead to intermittent faults.', 'seriousCause': 'If left unresolved, this could lead to complete ABS failure.'}
  5. {'cause': 'Mechanical issues (2% likelihood) - Issues such as wheel bearing failure or brake rotor problems can also affect the performance of the wheel speed sensor.', 'rareCause': 'Although rare, this could lead to significant braking issues and should be inspected immediately.'}
