What is C0475?
The Diagnostic Trouble Code (DTC) C0475 refers to a malfunction in the steering angle sensor circuit. This code is often triggered in vehicles like the 2010-2018 Chevrolet Silverado and GMC Sierra when there is an issue with the communication between the steering angle sensor and the vehicle's Engine Control Module (ECM). The steering angle sensor is crucial for systems like electronic stability control and traction control, as it provides the ECM with information about the steering wheel's position. If this sensor fails or the circuit is disrupted, it can lead to a variety of issues, including diminished handling performance and activated warning lights on the dashboard. In some cases, drivers might experience difficulty in steering or notice the vehicle behaving unpredictably during maneuvers. Addressing a C0475 code promptly is essential to ensure the safety and reliability of your vehicle, as ignoring it could potentially lead to further complications within the vehicle's steering and stability systems. Regular checks and maintenance of the steering system can help prevent this code from appearing, ensuring a smooth driving experience.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0475 is present:
- The 'Check Engine' light is illuminated on the dashboard, indicating a need for further diagnostics.
- Unusual steering behavior, such as the steering wheel feeling loose or unresponsive, especially when turning.
- The electronic stability control system may become disabled, causing the vehicle to handle poorly in slippery conditions.
- A noticeable decrease in fuel economy due to the ECM’s inability to optimize performance without accurate steering data.
- Increased wear on tires due to improper alignment or steering issues.
Possible Causes
Most common causes of C0475 (ordered by frequency):
- A faulty steering angle sensor is the most common cause, with a likelihood of about 60%. This can happen due to wear and tear or exposure to moisture.
- Wiring issues such as frayed wires or loose connections account for approximately 25% of cases, often resulting from physical damage or corrosion.
- Software glitches in the ECM or steering system contribute to about 10% of occurrences. Regular software updates can help prevent this.
- Less common causes include a malfunctioning ABS module, which can interfere with the steering angle data, and these issues may require specialized diagnostic tools.
- Rarely, a complete failure of the power steering system can trigger a C0475 code, which necessitates immediate attention.

Diagnostic Steps
Professional C0475 Diagnosis Process
Follow these systematic steps to accurately diagnose C0475. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Conduct an initial visual inspection for any obvious signs of damage to the wiring or connector of the steering angle sensor (5-10 minutes)
Step 2: Use the GeekOBD APP to perform an OBD2 scan for all fault codes and retrieve freeze frame data to analyze the context of the fault (10-15 minutes)
Step 3: Test the steering angle sensor with a multimeter to verify its output voltage and ensure it is within the manufacturer's specifications (20-30 minutes)
Step 4: Conduct a system function test post-repair to confirm that the steering and stability systems are operating correctly and clear any codes (10-15 minutes)
Step 5: Perform a road test under various conditions to ensure that all systems are functioning as expected and the C0475 code 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
