What vehicles are most commonly affected by C0E71?

The C0E71 code is frequently seen in vehicles like the 2016-2019 Ford Explorer and the 2017 Honda CR-V. Owners of these models should be particularly mindful of any stability control issues and ensure that their vehicle's systems are up to date.

How can I prevent C0E71 from happening again?

To prevent the C0E71 code from reappearing, perform regular maintenance checks on your vehicle's electrical systems and sensors. Keeping connections clean and free of corrosion, along with timely software updates, can help ensure that your vehicle's stability systems function correctly.

What is C0E71?

The C0E71 diagnostic trouble code refers to an issue often linked to the vehicle's traction control or stability system. This code commonly indicates a malfunction within the yaw rate sensor, which is responsible for monitoring the vehicle's rotational motion. When this sensor fails, it can lead to inaccurate readings, affecting the vehicle's stability control and ultimately compromising safety. Drivers may notice that the vehicle behaves unpredictably, especially during turns or slippery conditions. In vehicles such as the 2016-2019 Ford Explorer or the 2017 Honda CR-V, this error can trigger the check engine light, accompanied by potential issues like reduced traction control effectiveness. Ignoring the C0E71 code can lead to serious safety risks, particularly in adverse weather conditions. Therefore, it's crucial to address this code promptly. While it may seem like a minor issue, the implications for vehicle performance and safety are significant. Regular checks of the yaw rate sensor and associated wiring can help prevent this code from appearing, ensuring that your vehicle maintains optimal performance and safety standards.

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

Symptoms

Common symptoms when C0E71 is present:

  • The check engine light illuminates and stays lit, indicating an ongoing issue that needs addressing.
  • You may experience erratic handling or a lack of traction during acceleration or while turning, especially on wet or slippery surfaces.
  • Drivers report a noticeable decrease in fuel economy, potentially ranging from 10-15% due to the vehicle's systems not functioning optimally.
  • In some cases, the stability control light may also flash intermittently, indicating that the system is trying to compensate for the failure.
  • Unusual noises or vibrations may occur when the vehicle is in motion, particularly during sharp turns or sudden stops.

Possible Causes

Most common causes of C0E71 (ordered by frequency):

  1. The most common cause of the C0E71 code is a faulty yaw rate sensor, with a likelihood of about 70%. This sensor can fail due to physical damage or electrical issues.
  2. Another common cause could be damaged wiring or poor connections in the sensor circuit, which can lead to sporadic signals being sent to the vehicle's computer.
  3. It's also possible for software glitches in the vehicle's control module to trigger this code. Regular software updates can help prevent this issue.
  4. Less commonly, a failing ABS module might produce this code, affecting overall vehicle stability and safety.
  5. In rare cases, issues with the vehicle's power supply, such as a weak battery or poor ground connections, can lead to erroneous sensor readings.
