The most common cause of C1105 is a faulty wheel speed sensor, which can cost between $150 to $300 to replace. Other causes include damaged wiring or a malfunctioning ABS control module, with repair costs ranging from $100 to $1,200 depending on the issue.
Can I drive my car with C1105 or should I stop immediately?
While you can drive your car with C1105, it is not recommended. The ABS may not function properly, which can be dangerous in slippery conditions. It’s best to have the issue diagnosed and repaired as soon as possible.
How can I diagnose C1105 myself using GeekOBD APP?
You can use the GeekOBD APP to scan for DTCs and retrieve freeze frame data. This will help you understand when the code was triggered and under what conditions. Follow the diagnostic steps to further investigate the wheel speed sensor and related components.
What vehicles are most commonly affected by C1105?
C1105 is commonly found in vehicles like the 2010-2015 Honda Accord, 2006-2010 Toyota Camry, and 2015-2018 Ford F-150. These vehicles have been reported to experience issues with the ABS wheel speed sensors.
How can I prevent C1105 from happening again?
Regular maintenance is key to preventing C1105. Ensure your vehicle’s brake system is checked during routine services. Avoid driving through deep water and get any signs of electrical issues inspected early to prevent sensor damage.
What is C1105?
The Diagnostic Trouble Code (DTC) C1105 indicates a malfunction related to the ABS (Anti-lock Braking System) wheel speed sensor. This sensor plays a crucial role in monitoring the speed of each wheel to ensure optimal braking performance, especially during emergency braking situations. When the C1105 code is triggered, it often points to issues such as a faulty wheel speed sensor, wiring problems, or issues with the ABS control module. This can lead to the ABS warning light illuminating on the dashboard, and in some cases, the ABS system may become disabled. In practical terms, if this code appears, drivers may experience reduced braking efficiency, particularly under slippery road conditions. It’s important to address this issue promptly to maintain vehicle safety and performance. Common vehicles affected by this code include the 2010-2015 Honda Accord, 2006-2010 Toyota Camry, and 2015-2018 Ford F-150.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C1105 is present:
- The ABS warning light illuminates, indicating a problem with the braking system.
- The brakes may feel less responsive, especially during hard stops or slippery conditions.
- Inconsistent braking performance, such as the vehicle skidding or losing traction unexpectedly.
- The traction control system may also be disabled, leading to further handling issues.
- You may hear unusual noises from the ABS module when applying the brakes.
Possible Causes
Most common causes of C1105 (ordered by frequency):
- The most common cause is a faulty wheel speed sensor, which has a likelihood of about 60%. This can occur due to wear and tear, exposure to moisture, or physical damage.
- Another cause could be damaged wiring or connectors leading to the ABS sensor. Corrosion or frayed wires can disrupt the signal sent to the ABS control module.
- A malfunctioning ABS control module may also trigger C1105. This is less common but can happen due to internal failures or software issues, often requiring module replacement.
- Less common causes include issues with the brake system itself, such as air in the brake lines or low brake fluid levels, which can affect overall braking performance.
- Rarely, a faulty engine control unit (ECU) can misinterpret signals from the ABS system, leading to false codes and requiring extensive diagnostics.

Diagnostic Steps
Professional C1105 Diagnosis Process
Follow these systematic steps to accurately diagnose C1105. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Initial visual inspection - Check for obvious signs like damaged wiring, loose connections, or corrosion on the ABS sensor and wiring harness (5-10 minutes)
Step 2: OBD2 scan with GeekOBD APP - Retrieve all codes and freeze frame data to understand the fault context
Step 3: Component testing - Use a multimeter to measure resistance and voltage at the wheel speed sensor connectors, ensuring they meet manufacturer specifications (20-30 minutes)
Step 4: System function test - After any repairs, verify the proper operation of the ABS system by conducting a function test and clearing the codes using the GeekOBD APP (10-15 minutes)
Step 5: Road test verification - Drive the vehicle under various conditions to confirm the repair success and ensure the ABS light does not reappear (15-20 minutes)
Important Notes
- Always verify the repair with GeekOBD APP after completing diagnostic steps
- Clear codes and test drive to ensure the problem is resolved
- Address underlying causes to prevent code recurrence
