How can I diagnose C1044 myself using GeekOBD APP?
Using the GeekOBD APP, you can perform an OBD2 scan to retrieve DTC codes and inspect freeze frame data. Look for any abnormal readings related to wheel speed and check the sensor's output.
What vehicles are most commonly affected by C1044?
DTC C1044 is frequently observed in vehicles like the 2015-2019 Chevrolet Silverado and GMC Sierra. It's important to check for any recalls related to the ABS system in these models.
How can I prevent C1044 from happening again?
Regular vehicle maintenance, including checking and cleaning electrical connections and inspecting the wheel speed sensors, can help prevent C1044 from recurring. Keeping the vehicle free from excessive dirt and moisture is also beneficial.
What is C1044?
DTC C1044 refers to a diagnostic trouble code that indicates an issue with the wheel speed sensor circuit, commonly seen in vehicles like the 2015-2019 Chevrolet Silverado and GMC Sierra. This code points to a malfunction in the right front wheel speed sensor or the associated wiring and connectors. When the vehicle’s onboard diagnostics identify a discrepancy in the wheel speed data, it triggers this code to alert the driver. The wheel speed sensor is crucial for various vehicle systems, including anti-lock braking systems (ABS) and traction control. If the sensor fails or if there is a wiring issue, you may experience symptoms like the ABS warning light illuminating on your dashboard. This can lead to decreased braking efficiency, especially in slippery conditions. In addition, it could also affect the vehicle's stability control system, making it less safe to drive. Ignoring this code can lead to more severe issues over time, including complete failure of the ABS system, which compromises your vehicle's ability to stop safely. If you see this code, it's advisable to address the issue promptly to maintain your vehicle's performance and safety.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C1044 is present:
- ABS warning light illuminates on the dashboard, indicating a potential malfunction in the braking system.
- Vehicle experiences loss of traction control, leading to skidding or slipping during acceleration or braking on wet surfaces.
- Inconsistent or erratic speedometer readings, causing confusion while driving.
- Unusual noises from the wheels, such as grinding or clicking, indicating possible sensor or wiring issues.
- Decreased braking efficiency, making it harder to stop the vehicle quickly.
Possible Causes
Most common causes of C1044 (ordered by frequency):
- The most common cause of DTC C1044 is a faulty right front wheel speed sensor, which has a likelihood of about 60%. This can happen due to wear and tear or physical damage to the sensor.
- Another cause could be damaged wiring or loose connections in the sensor circuit, which can occur with age or exposure to harsh environmental conditions. This issue is seen about 25% of the time.
- Corrosion at the sensor connector can lead to signal loss, which is less common but can happen, accounting for about 10%. Regular inspection can prevent this.
- Failing ABS control module can trigger this code, although it's a rarer cause, estimated at 5%. This requires a more in-depth diagnostic approach.
- In some cases, a malfunction in the vehicle’s computer system can falsely trigger the C1044 code, though this is quite rare.

Diagnostic Steps
Professional C1044 Diagnosis Process
Follow these systematic steps to accurately diagnose C1044. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Perform an initial visual inspection of the wheel speed sensor and wiring for any visible damage 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 context of the fault (10-15 minutes)
Step 3: Conduct component testing of the wheel speed sensor with a multimeter to check its resistance and output signal (20-30 minutes)
Step 4: After any repairs, perform a system function test to verify that the ABS and traction control systems are functioning correctly and clear the codes (10-15 minutes)
Step 5: Finally, conduct a road test to ensure the issue is resolved and that the vehicle operates safely under various conditions (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
