What vehicles are most commonly affected by C035A?
The C035A code is frequently reported in vehicles like the 2015-2018 Chevrolet Silverado and GMC Sierra, as well as other GM models. It's wise to check for any recalls or technical service bulletins related to this code.
How can I prevent C035A from happening again?
Regular maintenance checks, especially after suspension work, can help prevent C035A. Ensure that the steering angle sensor is properly calibrated and that electrical connections are secure.
What is C035A?
The diagnostic trouble code (DTC) C035A refers to a malfunction in the steering angle sensor circuit. This sensor plays a crucial role in determining the steering wheel's position and angle, which is vital for various vehicle systems, including stability control and advanced driver-assistance systems (ADAS). When the C035A code is triggered, it usually indicates that the signal from the steering angle sensor is out of range or absent. This can lead to issues such as erratic steering behavior, compromised vehicle handling, and could potentially disable certain safety features. If you experience this code, it’s essential to address it promptly to avoid further complications such as increased wear on the vehicle's steering components or a complete failure of the steering system. Common vehicles affected by this code include the 2015-2018 Chevrolet Silverado and GMC Sierra, among others. Ignoring this code could not only affect your vehicle's performance but also your safety on the road. In summary, C035A indicates a serious issue that requires immediate attention, and understanding its implications can help you make informed decisions about repairs.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C035A is present:
- Check engine light illuminates and remains on, indicating a malfunction that needs immediate attention.
- Steering feels loose or unresponsive, which can lead to difficulty in controlling the vehicle, especially during turns.
- Vehicle's stability control system may become disabled, potentially compromising safety during adverse driving conditions.
- Increased steering effort, especially when turning, which can lead to fatigue during long drives.
- Unusual noises from the steering column, indicating possible mechanical issues with the steering system.
Possible Causes
Most common causes of C035A (ordered by frequency):
- Faulty steering angle sensor: This is the most common cause, with a likelihood of about 60%. The sensor may fail due to wear and tear or electrical issues.
- Wiring issues: Damaged or corroded wires can disrupt the signal transmission from the sensor, accounting for around 25% of cases. Inspecting the wiring harness is crucial.
- Improper calibration: A misaligned steering angle sensor can trigger the code, especially after suspension repairs. Regular checks can prevent this.
- Loose or damaged connectors: These can lead to intermittent signal loss, making up about 10% of cases. Ensuring a secure connection can mitigate this issue.
- Software issues: Rarely, the vehicle's software may need updating to fix underlying bugs that affect sensor readings.

Diagnostic Steps
Professional C035A Diagnosis Process
Follow these systematic steps to accurately diagnose C035A. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Perform an initial visual inspection
Step 1: Perform an initial visual inspection. Look for obvious signs of damage such as frayed wires, loose connectors, or corrosion around the steering angle sensor (5-10 minutes).
Step 2: Step 2: Use a diagnostic tool like the GeekOBD APP to scan for trouble codes
Step 2: Use a diagnostic tool like the GeekOBD APP to scan for trouble codes. This will provide detailed information about the C035A code and any other related codes that may be present (10-15 minutes).
Step 3: Step 3: Conduct component testing
Step 3: Conduct component testing. Use a multimeter to check the voltage output of the steering angle sensor and ensure it falls within the specified range (20-30 minutes).
Step 4: Step 4: Perform a system function test
Step 4: Perform a system function test. After repairs are made, clear the codes and verify that the steering angle sensor functions correctly during a short test drive (10-15 minutes).
Step 5: Step 5: Execute a road test
Step 5: Execute a road test. Drive the vehicle under various conditions to ensure that the repair was successful and that the C035A 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
