Common causes of the C064D code include a faulty steering angle sensor, wiring issues, and software glitches in the power steering control module. Repair costs can range from $100 for wiring repairs to $1000 for complete module replacements, depending on the nature of the issue.

Can I drive my car with C064D or should I stop immediately?

If you receive a C064D code, it is advisable to stop driving the vehicle as it may lead to loss of steering control. Schedule an inspection as soon as possible to prevent any safety hazards.

How can I diagnose C064D myself using GeekOBD APP?

To diagnose C064D using the GeekOBD APP, connect the app to your vehicle's OBD2 port. Perform a full scan to retrieve DTCs and check the freeze frame data for additional context. Look specifically for any abnormalities in the steering angle sensor readings.

What vehicles are most commonly affected by C064D?

While the C064D code can appear in various vehicles, it is notably prevalent in models such as the 2015-2018 Chevrolet Silverado and the 2016-2019 GMC Sierra. Always check for any recalls or technical service bulletins that may relate to your specific model.

How can I prevent C064D from happening again?

To prevent the C064D code from recurring, ensure regular maintenance of your vehicle's steering system, check for software updates from the manufacturer, and address any electrical issues immediately to prevent damage to the steering angle sensor.

What is C064D?

The C064D diagnostic trouble code (DTC) is a specific error code that indicates a problem with the vehicle's power steering control system. This code often pertains to issues with the steering angle sensor, which is critical for the vehicle's electronic stability control (ESC) and traction control systems. When the C064D code is triggered, it usually means that the power steering control module has detected an inconsistency or malfunction in the steering angle sensor readings. This can lead to various steering issues, potentially compromising vehicle handling and safety. Symptoms may include difficulty steering, warning lights on the dashboard, and an overall decrease in control while driving. Cars like the 2015-2018 Chevrolet Silverado and 2016-2019 GMC Sierra are known to experience this code more frequently. The practical implications of ignoring a C064D code can be severe, as it can lead to a loss of steering assistance, making it harder to maneuver the vehicle, especially at low speeds or during tight turns. Thus, addressing this code promptly is essential for maintaining vehicle safety and performance.

Symptoms

Common symptoms when C064D is present:

  • The steering wheel may feel stiff or unresponsive, making it difficult to turn the vehicle.
  • Dashboard warning lights, particularly the check engine light or power steering warning, may turn on.
  • Drivers may notice a sudden loss of power steering assist, especially when turning at low speeds.
  • Unusual noises may arise from the steering column, indicating potential mechanical failure.
  • Inconsistent steering responses can occur, causing a lack of control during high-speed driving.

Possible Causes

Most common causes of C064D (ordered by frequency):

  1. The most common cause of the C064D code is a faulty steering angle sensor, which is responsible for measuring the position of the steering wheel. This accounts for approximately 40% of cases.
  2. Another frequent cause is wiring issues, such as frayed wires or poor connections, which can disrupt the signal from the sensor to the power steering control module.
  3. Additionally, software glitches in the power steering control module can also trigger this code. Regular software updates can help prevent this issue.
  4. Less commonly, a malfunctioning power steering control module may be at fault, which can be diagnosed using advanced diagnostic tools.
  5. In rare instances, physical damage to the steering linkage or rack can trigger the C064D code, often requiring more extensive repairs.
