How can I prevent C065C from happening again?
Regular maintenance checks on your vehicle's steering system, including sensor inspections and ensuring proper wiring integrity, can help prevent the recurrence of the C065C code.
What is C065C?
The C065C diagnostic trouble code refers to a communication issue within the vehicle’s electronic control unit (ECU) system, specifically related to the steering angle sensor. It indicates that there is a malfunction or failure in the sensor's ability to relay its position to the vehicle's stability control system. When the steering angle sensor fails, it can cause issues with vehicle handling, particularly in adverse driving conditions such as rain or snow. This code is most commonly seen in vehicles like the 2015-2018 Chevrolet Silverado, but it can also affect other models from GM and related manufacturers. Drivers may notice symptoms like the traction control light illuminating or the vehicle behaving unpredictably in turns. Ignoring this code can lead to serious handling issues, potentially resulting in decreased safety while driving. Diagnosing and addressing the C065C code promptly is crucial to maintain optimal vehicle performance and safety.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C065C is present:
- The check engine light remains illuminated, indicating a persistent issue with the steering system.
- Unusual steering response, such as the steering wheel feeling loose or overly tight during turns.
- The traction control system warning light is active, suggesting a problem with vehicle stability.
- Difficulty in maintaining straight driving, as the vehicle may drift unexpectedly.
- Increased tire wear due to improper alignment caused by sensor issues.
Possible Causes
Most common causes of C065C (ordered by frequency):
- The most common cause is a faulty steering angle sensor, which has a likelihood of about 60%. This can occur due to wear and tear or electrical issues.
- Another potential cause is damaged wiring in the steering column, which can disrupt communication between the sensor and the ECU. This can happen due to physical damage or corrosion.
- Improper installation of aftermarket steering components can lead to misalignment of the sensor, causing a code C065C to trigger.
- Less commonly, a malfunctioning ECU could be at fault, which would require more extensive diagnostic testing to confirm.
- A rare but possible cause is a software glitch in the vehicle’s firmware, which might need an update from the manufacturer.

Diagnostic Steps
Professional C065C Diagnosis Process
Follow these systematic steps to accurately diagnose C065C. 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. Check for any obvious signs of damage like frayed wires or loose connections in the steering system (5-10 minutes).
Step 2: Step 2: Use an OBD2 scanner with the GeekOBD APP to retrieve all diagnostic codes and review freeze frame data for context (10-15 minutes)
Step 2: Use an OBD2 scanner with the GeekOBD APP to retrieve all diagnostic codes and review freeze frame data for context (10-15 minutes).
Step 3: Step 3: Conduct component testing on the steering angle sensor using a multimeter to ensure it is functioning correctly (20-30 minutes)
Step 3: Conduct component testing on the steering angle sensor using a multimeter to ensure it is functioning correctly (20-30 minutes).
Step 4: Step 4: After repairs, complete a system function test to verify proper operation and clear any stored codes (10-15 minutes)
Step 4: After repairs, complete a system function test to verify proper operation and clear any stored codes (10-15 minutes).
Step 5: Step 5: Conduct a road test under various conditions to confirm the repair's effectiveness and that the C065C code does not return (15-20 minutes)
