It is not advisable to drive your car with the C055D code, as it can lead to compromised steering control and increased risk of accidents.
How can I diagnose C055D myself using GeekOBD APP?
Using the GeekOBD APP, you can scan for trouble codes, view live data from the steering angle sensor, and analyze any inconsistencies in its operation.
What vehicles are most commonly affected by C055D?
DTC C055D is commonly found in GM vehicles, particularly the 2014-2019 Chevrolet Silverado and GMC Sierra, among others.
How can I prevent C055D from happening again?
Regular maintenance of your vehicle's electrical systems and keeping the steering system clean can help prevent issues with the steering angle sensor.
What is C055D?
DTC C055D is a diagnostic trouble code that indicates a malfunction within the steering angle sensor circuit, particularly in GM vehicles such as the Chevrolet Silverado (2014-2019) and GMC Sierra (2014-2019). The steering angle sensor is crucial for stability control and anti-lock braking systems. When this code appears, it often means that the vehicle's computer has detected an issue with the sensor's ability to accurately measure the steering wheel's angle. This can lead to compromised vehicle handling and stability, making it unsafe to drive. Drivers might notice issues like the steering wheel not returning to the center position or an illuminated warning light on the dashboard. Ignoring this code could lead to further complications, including reduced effectiveness of safety features and potential accidents. For a car owner, understanding DTC C055D is vital as it not only impacts how your vehicle drives but also your overall safety on the road. Addressing this issue promptly can prevent more extensive repairs down the line.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C055D is present:
- The check engine light or stability control light is illuminated, indicating a potential issue with the steering system.
- Steering feels unresponsive or overly loose, making it difficult to control the vehicle during turns.
- The vehicle may exhibit erratic behavior during acceleration or deceleration, particularly on slippery surfaces.
- The steering wheel may remain off-center after making turns, leading to an uncomfortable driving experience.
- Difficulty in engaging the traction control system, which may fail to activate when needed.
Possible Causes
Most common causes of C055D (ordered by frequency):
- The most common cause of DTC C055D is a faulty steering angle sensor, which occurs in about 60% of cases. This sensor can fail due to wear and tear or electrical issues.
- Another frequent cause is damaged wiring or connectors in the sensor circuit, which can lead to intermittent faults that trigger the code.
- Corrosion or dirt buildup on the sensor can also cause inaccurate readings, so keeping the area clean can help prevent issues.
- Less commonly, software glitches in the vehicle's ECU may lead to this code being triggered, which may require a software update to resolve.
- In rare cases, issues with the vehicle's power steering pump causing inconsistent pressure can affect sensor performance, leading to DTC C055D.

Diagnostic Steps
Professional C055D Diagnosis Process
Follow these systematic steps to accurately diagnose C055D. Each step builds on the previous one to ensure accurate diagnosis.
Step 1: Step 1: Initial visual inspection - Check the wiring and connectors related to the steering angle sensor for any signs of damage, corrosion, or loose connections (5-10 minutes)
Step 1: Initial visual inspection - Check the wiring and connectors related to the steering angle sensor for any signs of damage, corrosion, or loose connections (5-10 minutes).
Step 2: Step 2: OBD2 scan with GeekOBD APP - Use the GeekOBD APP to retrieve all fault codes and freeze frame data to gather context on the fault (10-15 minutes)
Step 2: OBD2 scan with GeekOBD APP - Use the GeekOBD APP to retrieve all fault codes and freeze frame data to gather context on the fault (10-15 minutes).
Step 3: Step 3: Component testing - Test the steering angle sensor using a multimeter to ensure it is functioning within specifications (20-30 minutes)
Step 3: Component testing - Test the steering angle sensor using a multimeter to ensure it is functioning within specifications (20-30 minutes).
Step 4: Step 4: System function test - After repairs, verify that the steering angle sensor is operational by conducting a function test and clearing the codes (10-15 minutes)
Step 4: System function test - After repairs, verify that the steering angle sensor is operational by conducting a function test and clearing the codes (10-15 minutes).
Step 5: Step 5: Road test verification - Take the vehicle for a drive to ensure that the steering response is normal and that no warning lights are illuminated (15-20 minutes)
