Common Questions
What does C1051 mean and how does it affect my car?
C1051 indicates a problem with the wheel speed sensor, which is essential for the ABS to function correctly. If this sensor is malfunctioning, you may notice the ABS light on your dashboard, and your vehicle might not stop as effectively, especially in wet or slippery conditions.
What are the most common causes of C1051 and how much does it cost to fix?
The most common cause of C1051 is a faulty wheel speed sensor, with repair costs typically ranging from $150 to $300 for replacement. Other causes can include damaged wiring or a malfunctioning ABS module, which can cost up to $800 to replace.
Can I drive my car with C1051 or should I stop immediately?
It is not advisable to drive your vehicle with a C1051 code present. The malfunction of the wheel speed sensor can lead to a failure of the ABS system, which is critical for safe braking performance. It's best to have it inspected and repaired as soon as possible.
How can I diagnose C1051 myself using GeekOBD APP?
Start by connecting the GeekOBD APP to your vehicle's OBD2 port. This will allow you to read the error codes. Look specifically for C1051 and any related codes that might provide more context. Use the app's capabilities to check freeze frame data, which shows the conditions when the code was triggered.
What vehicles are most commonly affected by C1051?
Commonly affected vehicles include the 2013-2018 Honda Accord, 2016-2020 Ford Fusion, and various models from Toyota and Nissan. It's advisable to check for any recalls or Technical Service Bulletins (TSBs) related to the ABS system for your specific make and model.
How can I prevent C1051 from happening again?
Regular maintenance is key to preventing C1051. Ensure that you have your braking system checked regularly, keep an eye on the condition of the wheel speed sensors, and clean any debris that might accumulate around them. Additionally, consider using high-quality parts during repairs to ensure longevity.
What is C1051?
The diagnostic trouble code (DTC) C1051 indicates a malfunction related to the wheel speed sensor. Typically found in vehicles such as the 2013-2018 Honda Accord and 2016-2020 Ford Fusion, this code is triggered when the ABS (Anti-lock Braking System) control module detects an issue with the signal from the wheel speed sensor. The wheel speed sensor is crucial for monitoring the speed of each wheel, allowing the ABS to function properly by preventing wheel lock-up during braking. A malfunction can lead to poor braking performance, affecting vehicle safety. This code often comes with symptoms like the ABS warning light illuminating on the dashboard, and in some cases, the vehicle may experience unexpected braking behavior. If left unaddressed, this could result in decreased vehicle control, especially in slippery conditions, increasing the risk of accidents. Therefore, understanding the implications of this code is vital for any car owner concerned about their vehicle's safety and performance.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C1051 is present:
- The ABS warning light stays illuminated, indicating a potential issue with the braking system.
- You may experience a loss of ABS function, leading to longer stopping distances in emergency braking situations.
- The vehicle might exhibit unusual braking behavior, such as pulsing or grabbing of brakes, especially on slippery surfaces.
- The traction control system may become disabled, impacting vehicle stability in adverse conditions.
- In some instances, the speedometer may display erratic readings, affecting overall driving experience.
Possible Causes
Most common causes of C1051 (ordered by frequency):
- The most common cause of C1051 is a faulty wheel speed sensor, which has a likelihood of about 60%. This can occur due to wear, damage, or corrosion.
- Another frequent cause is damaged wiring or connectors leading to the wheel speed sensor, which can disrupt the signal and is often overlooked during regular maintenance.
- A third cause could be a malfunctioning ABS control module, which may require specialized diagnostic equipment to confirm.
- Less common but serious is a brake system failure, where components such as the brake rotor or caliper may be involved.
- A rare cause could be the presence of foreign objects or debris obstructing the sensor's function, which is often identifiable during visual inspections.

Diagnostic Steps
Professional C1051 Diagnosis Process
Follow these systematic steps to accurately diagnose C1051. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Conduct an initial visual inspection of the wheel speed sensors and associated wiring for signs of damage, wear, or corrosion (5-10 minutes)
Step 2: Use the GeekOBD APP to perform an OBD2 scan and retrieve all codes, including freeze frame data, to understand the fault context (10-15 minutes)
Step 3: Test the suspected wheel speed sensor using a multimeter to check for proper voltage and resistance levels (20-30 minutes)
Step 4: After replacing any faulty components, conduct a system function test to verify proper operation and clear the codes from the memory (10-15 minutes)
Step 5: Perform a road test under various conditions to ensure that the repairs were successful and that the ABS warning 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
