Common Questions
What does C0017 mean and how does it affect my car?
C0017 signals an issue with the left front wheel speed sensor. This can affect your vehicle’s braking and stability control, posing a safety risk. Addressing it promptly ensures optimal vehicle performance.
What are the most common causes of C0017 and how much does it cost to fix?
Common causes include a faulty wheel speed sensor (60% likelihood) and wiring issues. Repair costs can range from $100 to $300 for sensor replacement, with wiring repairs costing between $50 and $150.
Can I drive my car with C0017 or should I stop immediately?
It’s advisable to avoid driving the vehicle until the issue is resolved. Driving with a C0017 code may compromise braking performance, especially in wet or icy conditions.
How can I diagnose C0017 myself using GeekOBD APP?
Using the GeekOBD APP, perform an OBD2 scan to retrieve codes. Analyze freeze frame data for context, and check the left front wheel speed sensor's readings for abnormalities.
What vehicles are most commonly affected by C0017?
Commonly affected vehicles include the 2010-2015 Chevrolet Silverado and GMC Sierra. Checking for any recalls or TSBs related to wheel speed sensors is advisable.
How can I prevent C0017 from happening again?
Regularly inspect brake components and wiring for wear or damage. Keeping the vehicle clean from road debris and moisture can also help prolong sensor lifespan.
What is C0017?
The Diagnostic Trouble Code (DTC) C0017 indicates a wheel speed sensor issue, specifically related to the left front wheel speed sensor circuit. This code is most commonly found in vehicles like the Chevrolet Silverado (2010-2015) and GMC Sierra models. When the vehicle's onboard diagnostic system detects that the signal from the left front wheel speed sensor is either out of range or not functioning, it triggers the C0017 code. The wheel speed sensors are vital for the Anti-lock Braking System (ABS) and Electronic Stability Control (ESC), as they provide real-time data about each wheel's speed to help maintain traction and control. If this code appears, it may lead to issues such as the ABS light illuminating on the dashboard, potential loss of traction control, and compromised braking performance. Ignoring this issue can lead to reduced vehicle safety, especially during adverse weather conditions where traction is crucial. It’s important to address this code promptly, as it could indicate a failing sensor or wiring issues that could escalate into more significant problems if left unattended.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0017 is present:
- Check engine light stays on constantly, indicating a persistent issue that requires attention.
- ABS warning light illuminates on the dashboard, signaling potential problems with the braking system.
- Engine hesitates or feels unstable during acceleration, as the vehicle's computer struggles to manage traction control effectively.
- Increased stopping distance due to compromised ABS functionality, which can lead to unsafe driving conditions.
- Unusual noises from the brake system, such as grinding or clicking, which may indicate wear or failure in the braking components.
Possible Causes
Most common causes of C0017 (ordered by frequency):
- Faulty wheel speed sensor - A common cause accounting for about 60% of C0017 cases is a malfunctioning sensor that fails to send accurate readings.
- Wiring issues - Damaged or corroded wiring can lead to intermittent signals, often due to exposure to road conditions or age.
- Connector problems - Loose or corroded connectors at the sensor can disrupt communication, leading to erratic sensor performance.
- ABS control module failure - Though less common, this can occur and may require replacement of the entire module.
- Faulty brake control system - Rarely, a problem with the overall brake control system can manifest as a C0017 code.

Diagnostic Steps
Professional C0017 Diagnosis Process
Follow these systematic steps to accurately diagnose C0017. 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 (5-10 minutes)
Step 2: OBD2 scan with GeekOBD APP - Retrieve all codes and freeze frame data to understand the fault context (10-15 minutes)
Step 3: Component testing - Use a multimeter or specific diagnostic tools to test the left front wheel speed sensor and its circuit (20-30 minutes)
Step 4: System function test - Verify proper operation after repairs and clear codes using the GeekOBD APP (10-15 minutes)
Step 5: Road test verification - Drive the vehicle under various conditions to confirm repair success and ensure the ABS functions properly (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
