What vehicles are most commonly affected by C079E?
The C079E code is frequently seen in 2015-2018 Ford F-150 models, but it can also occur in other vehicles with similar electronic stability control systems.
How can I prevent C079E from happening again?
Regular maintenance checks on your vehicle's electronic systems, ensuring wiring integrity, and keeping software updated can help prevent the C079E code from recurring.
What is C079E?
The DTC C079E code refers to a specific fault within the vehicle's electronic control systems, particularly related to the steering angle sensor or the stability control module. This code is often triggered when the system detects a malfunction in the communication between the steering angle sensor and the electronic stability control (ESC) module. For vehicle owners, this means that the vehicle may experience issues with stability control, potentially impacting handling and safety. The C079E code is predominantly found in various models, including the 2015-2018 Ford F-150, and can lead to the 'Check Engine' or 'Stability Control' warning lights illuminating on the dashboard. Ignoring this code can result in compromised vehicle handling, particularly in adverse driving conditions, which might escalate the risk of accidents. Therefore, addressing the C079E code promptly is crucial to ensure the vehicle’s safety systems function correctly, as well as to maintain optimal vehicle performance in both normal and challenging driving scenarios.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C079E is present:
- The Check Engine light stays on constantly, indicating an issue that requires immediate diagnostic attention.
- Drivers may notice the vehicle's steering feels unresponsive or unusually heavy, especially during turns.
- The vehicle's stability control system may activate unexpectedly, causing the traction control light to illuminate.
- There might be a noticeable decrease in fuel economy, suggesting that the vehicle's systems are not operating efficiently.
- In some cases, the steering wheel may be misaligned, causing the vehicle to drift to one side while driving.
Possible Causes
Most common causes of C079E (ordered by frequency):
- The most common cause of the C079E code is a faulty steering angle sensor, which has a likelihood of about 60%. This sensor plays a crucial role in communicating the steering position to the ESC module.
- A malfunction in the wiring or connectors related to the steering angle sensor can also trigger this code, with a likelihood of around 30%. Damaged wiring can prevent proper sensor function.
- In some cases, a software glitch in the ESC module can lead to the C079E code. Regular software updates can help prevent this issue.
- Less common but serious causes include a failing ESC module, which could lead to complete loss of stability control.
- A rare cause is an issue with the vehicle's power supply, such as a weak battery, affecting the performance of electronic systems.
