Common Questions

What does C0367 mean and how does it affect my car?

C0367 means there's an issue with the steering angle sensor. This sensor is vital for your vehicle's stability and traction systems. If this code is triggered, it can lead to poor handling, especially in slippery conditions, and may even cause warning lights to illuminate. It’s crucial to address this issue to maintain safe driving conditions.

What are the most common causes of C0367 and how much does it cost to fix?

Common causes include a faulty steering angle sensor, damaged wiring, or ECU issues. Repair costs can vary, typically ranging from $100 to $300 depending on whether you need a simple wiring fix or a full sensor replacement.

Can I drive my car with C0367 or should I stop immediately?

It's advised to stop driving your vehicle if you see the C0367 code. Continued driving can lead to unpredictable handling and may compromise your safety. It’s best to have it diagnosed and repaired promptly.

How can I diagnose C0367 myself using GeekOBD APP?

To diagnose C0367, connect the GeekOBD APP to your vehicle’s OBD2 port. Use the app to read the code and view freeze frame data for the conditions under which the error occurred. This information can guide your investigation into the specific sensor or wiring issues.

What vehicles are most commonly affected by C0367?

C0367 is frequently seen in 2015-2018 Chevrolet Silverado and GMC Sierra models. Other vehicles may experience this code, but these models are particularly prone to steering angle sensor issues according to user reports and service bulletins.

How can I prevent C0367 from happening again?

Regular maintenance checks, including inspections of the steering components and wiring harnesses, can help catch potential issues early. Keeping the vehicle clean and protecting electrical connections from moisture can also prevent corrosion.

What is C0367?

Diagnostic Trouble Code (DTC) C0367 refers to an issue with the steering angle sensor signal, particularly in models like the 2015-2018 Chevrolet Silverado and GMC Sierra. This code indicates that the steering angle sensor is either malfunctioning or sending an incorrect signal to the vehicle's control module. The steering angle sensor plays a crucial role in ensuring the stability control system and traction control system function correctly. When this code is triggered, it can lead to a variety of performance issues, such as difficulty in steering, unpredictable handling, and the potential for the traction control system to disengage. In real-world terms, if you notice the check engine light illuminated along with the code C0367, it’s an indicator that your vehicle may not respond as expected during turns or slippery conditions, putting your safety at risk. Ignoring this code can lead to further complications, including complete steering system failure, which can be dangerous while driving. It's essential to address this code promptly by diagnosing the underlying causes and taking appropriate action to correct the issue.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C0367 is present:

  • The check engine light stays on constantly, indicating an ongoing issue with the vehicle's electronic systems.
  • You may feel the steering wheel is unresponsive or stiff during turns, affecting maneuverability.
  • Drivers often report a significant decrease in vehicle stability, especially on slippery roads or during sudden direction changes.
  • Traction control and stability control warning lights may illuminate, indicating that these safety systems are compromised.
  • In some cases, the vehicle may enter limp mode, limiting engine power and speed for safety.

Possible Causes

Most common causes of C0367 (ordered by frequency):

  1. The most common cause of C0367 is a faulty steering angle sensor, which has a likelihood of around 60%, often due to wear and tear or electrical failure.
  2. A loose or damaged wiring harness that connects the sensor to the control module can also trigger this code, accounting for about 25% of cases, usually due to environmental exposure.
  3. Corrosion at the connector terminals is another possible cause, which can be prevented by regular inspections and ensuring that the electrical components are protected from moisture.
  4. Less commonly, a malfunctioning Electronic Control Unit (ECU) can result in this error, though this is less frequent and requires more in-depth diagnostics.
  5. Finally, a rare but possible cause could be a software glitch within the vehicle's system, which might require a software update or reprogramming.
