Common Questions
What does C0117 mean and how does it affect my car?
C0117 indicates an issue with your vehicle's ABS wheel speed sensor circuit. This can affect your braking system, potentially leading to decreased braking efficiency. If ignored, it could compromise your safety while driving.
What are the most common causes of C0117 and how much does it cost to fix?
The most common cause of C0117 is a faulty wheel speed sensor, with repair costs typically ranging from $100 to $300. Other causes include damaged wiring and ABS module issues, which can vary in cost but should be diagnosed quickly to prevent further damage.
Can I drive my car with C0117 or should I stop immediately?
It's advised to stop driving your vehicle if you see the C0117 code, as it indicates a malfunction in your braking system. Continuing to drive can lead to potential safety hazards.
How can I diagnose C0117 myself using GeekOBD APP?
To diagnose C0117 using the GeekOBD APP, first connect the app to your vehicle's OBD2 port. Perform a scan to retrieve any trouble codes, then look for the C0117 code. You can also check the freeze frame data for additional context.
What vehicles are most commonly affected by C0117?
C0117 is commonly reported in vehicles such as the 2010-2015 Ford F-150, 2008-2013 Chevrolet Silverado, and various models from Toyota and Honda. Checking for recalls and TSBs can provide more insights into specific issues.
How can I prevent C0117 from happening again?
Regular maintenance, such as inspecting the ABS system and ensuring all connections are secure, can help prevent C0117. Additionally, cleaning the wheel speed sensors and avoiding driving on rough terrains can reduce wear.
What is C0117?
The diagnostic trouble code (DTC) C0117 indicates a problem with the ABS (Anti-lock Braking System) wheel speed sensor circuit. Specifically, this code suggests that the signal from the wheel speed sensor is either too high or too low, which can compromise the vehicle's braking performance. When the ABS system detects an inconsistency in the wheel speed sensor's data, it triggers the C0117 code to alert the driver. This issue is particularly prevalent in vehicles like the 2010-2015 Ford F-150, where wear and tear on components can lead to sensor failures. If left unaddressed, C0117 can result in the ABS warning light illuminating on your dashboard, and in some cases, it may lead to a complete failure of the ABS system, making braking less effective during emergency situations. This not only poses a risk to your safety but can also lead to more extensive repairs if not diagnosed and repaired promptly. Knowing how to recognize the symptoms, causes, and solutions associated with DTC C0117 can save you time and money in the long run.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0117 is present:
- The ABS warning light illuminates on your dashboard, indicating a malfunction in the braking system.
- You may experience decreased braking performance, particularly in emergency situations, due to malfunctioning ABS.
- The vehicle may exhibit unusual brake behavior, such as skidding or locking up during hard braking.
- You might notice a grinding or buzzing noise when you apply the brakes, signaling potential sensor issues.
- In some cases, the vehicle may enter 'limp mode,' reducing engine power to prevent further damage.
Possible Causes
Most common causes of C0117 (ordered by frequency):
- The most common cause of C0117 is a faulty wheel speed sensor, which accounts for about 60% of cases. This can happen due to exposure to dirt, moisture, or physical damage.
- Another common issue is damaged wiring or connectors in the ABS system, which can disrupt the sensor's signal and is often caused by wear and tear over time.
- A malfunctioning ABS control module can also trigger this code, though this is less common. Regular inspection can prevent this issue from arising.
- Less common causes might include a damaged tone ring, which affects the sensor's ability to function correctly; this is particularly relevant in vehicles with exposed wheel components.
- In rare cases, software issues in the ABS control unit can result in false readings, leading to a C0117 code being set.
