How can I prevent C087F from happening again?

Regular maintenance, including checking the steering components and ensuring electrical connections remain intact, can help prevent C087F. Additionally, keeping your vehicle’s software updated can reduce the risk of software-related issues.

What is C087F?

The diagnostic trouble code (DTC) C087F indicates a problem with the vehicle’s steering angle sensor, specifically related to the yaw rate sensor in various models, particularly in Chevrolet vehicles like the 2016-2020 Silverado. This code is typically triggered when the steering angle sensor fails to communicate accurately with the vehicle’s electronic stability control (ESC) system, impacting the overall handling and safety features of your car. In practical terms, a C087F code can lead to issues such as the traction control system disabling itself, which could compromise vehicle stability during driving, especially in slippery conditions. The steering angle sensor plays a crucial role in detecting the angle at which the steering wheel is turned, and if it malfunctions, it can affect advanced driver assistance systems (ADAS). Ignoring this code can lead to significant safety concerns, making it essential for vehicle owners to address it promptly to ensure optimal vehicle performance and safety.

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

Symptoms

Common symptoms when C087F is present:

  • The check engine light illuminates and stays on, indicating a persistent issue that requires attention from a technician.
  • The traction control light may flash or remain illuminated, signaling that the vehicle's traction control system is compromised.
  • Drivers may experience unusual handling or steering response, such as the vehicle feeling unstable during turns or acceleration.
  • Inconsistent steering performance may occur, where the steering wheel feels loose or unresponsive during driving.
  • The electronic stability control system may deactivate, leaving the vehicle vulnerable during adverse driving conditions.

Possible Causes

Most common causes of C087F (ordered by frequency):

  1. The most common cause of C087F is a faulty steering angle sensor, which has a likelihood of around 60%. This sensor can be damaged due to wear, moisture, or electrical issues.
  2. A second common cause includes wiring problems related to the steering angle sensor. Damaged connectors or frayed wires can interrupt communication, accounting for approximately 25% of cases.
  3. Thirdly, software issues within the vehicle’s ESC module could trigger this code, often resolved through software updates or recalibrations.
  4. A less common but serious cause could be a malfunctioning ESC module itself, which may require replacement and can lead to major repair costs.
  5. Rare causes may include issues with the vehicle’s battery or electrical system, which can create erratic sensor readings and trigger codes like C087F.
