What is C0C70?
DTC C0C70 is a diagnostic trouble code that indicates a problem with the vehicle's yaw rate sensor, often found in models like the 2015-2019 Ford Fusion and Ford Escape. The yaw rate sensor measures the vehicle's rotation around its vertical axis, which is crucial for stability control systems. When this sensor malfunctions, it can lead to issues with traction control, electronic stability control, and even anti-lock braking systems. A malfunctioning sensor can cause the system to provide inaccurate data, potentially leading to unsafe driving conditions. Car owners might notice that their traction control light remains illuminated or that the vehicle feels unstable during turns. Ignoring this code can result in decreased vehicle safety, as the systems that rely on accurate sensor data may not function as intended. It's essential to address this issue promptly to ensure the vehicle operates safely and effectively.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0C70 is present:
- The traction control light stays on constantly, indicating a potential issue with the stability system.
- The car experiences unexpected movements, such as slipping or swaying during turns, leading to a lack of confidence when driving.
- Fuel economy may decrease by 10-20%, as the vehicle's stability systems may cause the engine to work harder to maintain traction.
- The ABS warning light may also illuminate, suggesting that the anti-lock braking system is affected.
- Unusual noises or vibrations may be felt while driving, especially during cornering maneuvers.
Possible Causes
Most common causes of C0C70 (ordered by frequency):
- The most common cause of the C0C70 code is a faulty yaw rate sensor, which has a likelihood of about 70%. This sensor can fail due to wear and tear or exposure to moisture.
- Another potential cause is damaged wiring or connectors related to the yaw rate sensor, which can lead to intermittent signals and trigger the code.
- A third cause could be a malfunction in the vehicle's stability control module, which may misinterpret sensor data. Regular inspections of the stability control system can help prevent this.
- Less common but serious causes include software glitches in the vehicle's control systems that may require a software update from the manufacturer.
- A rare cause could be a severe impact or accident that dislodges the sensor or its wiring, which would necessitate a thorough inspection following any collision.
