How can I diagnose C1473 myself using GeekOBD APP?
To diagnose C1473, start by connecting your GeekOBD APP to the OBD2 port. Retrieve the diagnostic codes and check the freeze frame data for additional context. Perform a visual inspection and test the steering angle sensor's voltage output.
What vehicles are most commonly affected by C1473?
C1473 is frequently reported in vehicles like the 2014-2019 Chevrolet Silverado and other GM models equipped with electronic stability control systems.
How can I prevent C1473 from happening again?
To prevent C1473, regularly inspect your vehicle's steering system for wear, keep electrical connections clean and secure, and perform routine maintenance on suspension components.
What is C1473?
The C1473 diagnostic trouble code (DTC) indicates an issue with the steering angle sensor in your vehicle, particularly common in models like the 2014-2019 Chevrolet Silverado. This code suggests that the steering angle sensor, which measures the position of the steering wheel, is either malfunctioning or sending an incorrect signal to the vehicle's computer. When this sensor fails, it can lead to problems with the vehicle's stability control system, traction control, and can even affect the performance of the anti-lock braking system (ABS). A malfunctioning steering angle sensor may result in the 'Service Stabilitrak' warning light illuminating on the dashboard, and the vehicle may exhibit unstable handling, particularly in slippery conditions. Understanding this code is crucial because a faulty sensor can compromise vehicle safety and handling, leading to potential accidents if not addressed promptly. To ensure your vehicle operates safely, it is essential to diagnose and fix the issue represented by DTC C1473 as soon as it appears.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C1473 is present:
- Check engine light stays on, indicating a persistent issue with the steering angle sensor.
- Vehicle stability control warning light appears, often accompanied by the 'Service Stabilitrak' message.
- Steering feels unresponsive or loose, particularly during tight turns, affecting your control over the vehicle.
- Increased tire wear due to improper alignment from sensor misreadings.
- Difficulty in engaging the cruise control system, which is often linked to the steering angle sensor's readings.
Possible Causes
Most common causes of C1473 (ordered by frequency):
- The most common cause of C1473 is a faulty steering angle sensor itself, which has a likelihood of 60%. This can occur due to wear and tear or exposure to moisture.
- Another common cause (20%) is damaged wiring or connectors leading to the sensor, which can interrupt the signal sent to the vehicle's computer.
- A misalignment of the steering system can also cause this code, particularly after a collision or suspension work (15%). Regular inspections can help prevent this.
- Less common but serious causes include issues with the vehicle's electronic control unit (ECU), which may misinterpret sensor data, requiring an ECU reset or replacement.
- Rarely, a software glitch in the vehicle’s stability control system might trigger this code without a hardware issue.

Diagnostic Steps
Professional C1473 Diagnosis Process
Follow these systematic steps to accurately diagnose C1473. 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 around the steering angle sensor (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 to test the steering angle sensor and confirm its voltage output is within specifications (20-30 minutes)
Step 4: System function test - After any repairs, verify proper operation of the steering angle sensor and clear codes with the GeekOBD APP (10-15 minutes)
Step 5: Road test verification - Drive the vehicle under various conditions to confirm that the steering functions correctly and all warning lights are off (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
