How can I diagnose C0368 myself using GeekOBD APP?
Using the GeekOBD APP, you can perform an OBD2 scan to retrieve the C0368 code and any additional codes, providing insight into the issue. Follow the prompts to access freeze frame data for deeper analysis.
What vehicles are most commonly affected by C0368?
C0368 is frequently seen in 2015-2018 Chevrolet Silverado models, but it can also occur in other GM vehicles from this range. Always check for any recalls or Technical Service Bulletins (TSBs) related to your vehicle.
How can I prevent C0368 from happening again?
Regular maintenance checks, ensuring proper calibration after repairs, and avoiding rough driving can help prevent the recurrence of the C0368 code.
What is C0368?
The Diagnostic Trouble Code (DTC) C0368 indicates a problem with the steering angle sensor circuit, specifically in vehicles like the 2015-2018 Chevrolet Silverado. This code often arises due to issues in the sensor's calibration or wiring, which can lead to compromised steering performance. When this DTC is triggered, it implies that the vehicle's onboard computer has detected an abnormality in the steering angle sensor's input signal. This sensor is crucial for several functions, including electronic stability control and traction control systems. If the sensor is not functioning correctly, drivers may experience a loss of these important safety features, leading to potential handling issues. Furthermore, ignoring this code can lead to more significant problems such as uneven tire wear, compromised handling during turns, or even difficulty in steering. Therefore, addressing the C0368 code promptly is essential for maintaining vehicle safety and performance.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0368 is present:
- The check engine light is illuminated, signaling a problem with the steering angle sensor.
- Drivers might notice inconsistent steering response, making it feel loose or overly sensitive during turns.
- The stability control warning light may be triggered, indicating that the vehicle's stability systems are compromised.
- You may experience difficulty in steering, particularly in tight turns or during parking maneuvers.
- In some cases, the vehicle may exhibit abnormal tire wear due to misalignment caused by the faulty sensor.
Possible Causes
Most common causes of C0368 (ordered by frequency):
- The most common cause of C0368 is a faulty steering angle sensor, which has a likelihood of about 60%. This can occur due to wear and tear or exposure to moisture.
- A second cause could be damaged wiring or connectors in the steering system, which may account for around 25% of cases. These issues can arise from physical damage or corrosion.
- Improper calibration after a repair or steering component replacement is another potential cause, with a 10% likelihood. Regular checks can prevent this problem.
- Less common causes may include a malfunctioning electronic control unit (ECU), which could lead to erroneous signals being sent to the steering angle sensor.
- A rare but possible cause is software glitches in the vehicle's onboard systems, which can usually be resolved with a firmware update.
