What is C071D?

The Diagnostic Trouble Code (DTC) C071D indicates a problem with the vehicle dynamics control system, often related to the steering angle sensor. This code typically appears in vehicles equipped with advanced stability control systems, such as the 2015-2020 Ford Explorer and similar models across various manufacturers. When your vehicle's computer detects that the steering angle sensor is providing incorrect data, it triggers the C071D code. This can lead to a range of issues, including loss of traction control, reduced stability when cornering, and potential safety risks during adverse weather conditions. Drivers may experience altered steering response or feel a lack of control when navigating turns. Addressing this code is crucial not only for optimal vehicle performance but also for maintaining safety standards. Ignoring the C071D code can exacerbate the underlying issue, leading to further complications and expensive repairs down the line. Therefore, it's advisable to address the problem as soon as it is detected to ensure your vehicle operates safely and efficiently.

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

Symptoms

Common symptoms when C071D is present:

  • The check engine light illuminates, indicating a diagnostic trouble code has been registered.
  • Drivers may notice the vehicle feels unstable, especially during turns or sudden maneuvers, leading to a lack of confidence in steering control.
  • You may experience a decrease in fuel efficiency, potentially ranging from 5-10% as the engine works harder to compensate for stability issues.
  • In some cases, the traction control light may activate, signaling that the system is unable to maintain optimal traction due to faulty data from the steering angle sensor.
  • Unusual steering feedback can occur, such as a stiffer steering wheel or delayed response when making turns.

Possible Causes

Most common causes of C071D (ordered by frequency):

  1. The most common cause of the C071D code (approximately 60% likelihood) is a faulty steering angle sensor, which can wear out over time or become misaligned due to impacts or accidents.
  2. Another potential cause (about 25%) is damaged wiring or poor electrical connections within the vehicle's stability control module, often exacerbated by corrosion or wear.
  3. A failing or miscalibrated electronic stability control (ESC) module can also trigger this code, impacting the system's ability to accurately interpret steering input and maintain vehicle stability.
  4. Less common (around 10%), but serious causes can include issues with the vehicle's power steering system, which can lead to complete steering failure if not addressed promptly.
  5. Rarely, a software glitch in the vehicle's onboard computer can cause erroneous readings from the steering angle sensor, leading to the C071D code being triggered without any physical faults.
