What is C0F47?
The DTC code C0F47 is primarily associated with the vehicle's Advanced Driver Assistance Systems (ADAS), particularly in vehicles like the 2016-2020 Ford Explorer. This code indicates that the system has detected a malfunction related to the Adaptive Cruise Control functionality or other safety features. When this code is triggered, it usually means that the vehicle's computer has identified a fault within the sensors or the wiring that connects those sensors to the control module. This malfunction can lead to the Adaptive Cruise Control system not functioning correctly, resulting in decreased driving safety and increased risk of an accident. Additionally, you may notice that related features, such as lane-keeping assist or automatic emergency braking, may also be compromised. If left unaddressed, the underlying issues could worsen over time, leading to more extensive repairs. It's crucial for car owners to understand that this code is not just a simple annoyance; it represents a genuine safety concern that should be diagnosed and resolved promptly.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0F47 is present:
- The check engine light illuminates, and it remains on, indicating a persistent issue with the vehicle's systems.
- You may experience a lack of response from the Adaptive Cruise Control system, meaning it may not engage or disengage as expected while driving.
- Drivers might notice unusual behavior in other ADAS features, such as erratic lane-keeping assistance or failure of automatic braking, which can compromise safety.
- Inconsistent warnings or alerts on the dashboard related to cruise control or safety features, causing confusion or concern.
- A noticeable decrease in fuel efficiency, potentially by 10-15%, due to the malfunctioning system causing the engine to work harder.
Possible Causes
Most common causes of C0F47 (ordered by frequency):
- The most common cause of C0F47 is a faulty or misaligned sensor, which can occur in about 60% of cases. This can happen due to dirt, damage, or improper installation during servicing.
- Another frequent cause is wiring issues, such as frayed wires or poor connections, which can impair the signals sent to the control module.
- In some cases, software glitches within the vehicle's control module may cause this code to trigger. Regular software updates can help prevent such issues.
- Less commonly, mechanical failures in the cruise control actuator can lead to this code, though it is a serious concern that requires immediate attention.
- A rare cause could be environmental factors affecting the sensors, such as extreme weather conditions or debris on the road.
