Common Questions

What does C071C mean and how does it affect my car?

The C071C code indicates an issue with your vehicle's yaw rate sensor, which is critical for maintaining traction and stability. If this sensor is malfunctioning, you may notice that your car handles poorly, especially in adverse conditions like rain or snow. Long-term neglect of this issue can lead to more serious handling problems and increase the risk of accidents.

What are the most common causes of C071C and how much does it cost to fix?

Common causes of the C071C code include a faulty yaw rate sensor, wiring issues, or improper calibration following maintenance. Repair costs can vary depending on the specific issue, with sensor replacement typically ranging from $150 to $300, while wiring repairs might be around $100 to $200.

Can I drive my car with C071C or should I stop immediately?

While it may be possible to drive your vehicle with the C071C code, it is not advisable. The malfunction can lead to compromised stability and increased risk of losing control, particularly in adverse weather conditions. It’s best to address this issue as soon as possible.

How can I diagnose C071C myself using GeekOBD APP?

To diagnose the C071C code using the GeekOBD APP, connect the device to your car's OBD2 port, and use the app to scan for trouble codes. Review the freeze frame data to see when the code was triggered, and check for any other related codes that might provide additional context.

What vehicles are most commonly affected by C071C?

The C071C code is most commonly found in vehicles like the 2015-2019 Ford Explorer and other models from Ford, Lincoln, and some Mazda vehicles. It's important to check for any manufacturer recalls or technical service bulletins related to this issue.

How can I prevent C071C from happening again?

Preventing the C071C code from reoccurring involves regular maintenance, including checking the yaw rate sensor during routine inspections. Ensuring that any suspension work is done correctly and recalibrating the sensor after tire changes can also help.

What is C071C?

The DTC code C071C is primarily associated with the vehicle's traction control system. This code indicates that there is an issue with the yaw rate sensor, which is crucial for stability control. When this sensor fails or becomes misaligned, your vehicle may struggle to maintain traction, especially during slippery conditions. This can lead to poor handling and increased stopping distances, posing a significant safety risk. The yaw rate sensor measures the vehicle's rotation around its vertical axis, helping the stability control system determine how much correction is necessary to keep the vehicle on its intended path. If you see this code, it may be accompanied by other warnings, such as the traction control or stability control lights illuminating on your dashboard. Ignoring this code can lead to further complications, including potential damage to other vehicle systems or components. It's essential to address it promptly to ensure your car remains safe and reliable on the road.

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

Symptoms

Common symptoms when C071C is present:

  • The traction control light on the dashboard illuminates, indicating a malfunction in the system.
  • You may experience poor handling or instability while driving, especially during turns or on slippery roads.
  • The vehicle may feel like it is sliding or skidding even when driving on dry pavement.
  • The stability control light may also activate, further indicating issues with vehicle dynamics.
  • In some cases, the vehicle may enter 'limp mode,' reducing engine power to prevent further damage.

Possible Causes

Most common causes of C071C (ordered by frequency):

  1. The most common cause of a C071C code is a malfunctioning yaw rate sensor, which occurs in approximately 60% of cases. This can be due to electrical failure or physical damage.
  2. Another frequent culprit is faulty wiring or poor connections to the yaw rate sensor, which can lead to inaccurate readings.
  3. In some instances, calibration issues after tire changes or suspension work can trigger the code, highlighting the importance of proper alignment.
  4. Less common causes can include issues with the ABS module, which may affect the stability control system.
  5. A rare cause could be software glitches in the vehicle's control systems, which may require reprogramming or updates.
