Common Questions
What does C05CE mean and how does it affect my car?
C05CE indicates a malfunction in the Adaptive Cruise Control system, which could compromise your driving safety if not addressed. It affects how your vehicle maintains speed and distance from other vehicles, potentially leading to erratic behavior during highway driving.
What are the most common causes of C05CE and how much does it cost to fix?
The most common causes of C05CE include faulty sensors and wiring issues. Repair costs can range from $150 for simple wiring repairs to $800 for complete sensor replacements.
Can I drive my car with C05CE or should I stop immediately?
While you can drive your vehicle, it’s not advisable. The malfunctioning cruise control can pose safety risks. It is recommended to have it diagnosed and repaired as soon as possible.
How can I diagnose C05CE myself using GeekOBD APP?
With the GeekOBD APP, you can perform an OBD2 scan, view live data from the ACC system, and check for additional trouble codes that may provide more context for the C05CE code.
What vehicles are most commonly affected by C05CE?
C05CE is commonly found in 2016-2020 Ford Explorers and other vehicles equipped with advanced cruise control systems. Checking for manufacturer recalls or technical service bulletins (TSBs) can provide additional insights.
How can I prevent C05CE from happening again?
Regular maintenance, including sensor cleaning and software updates, can help prevent C05CE from recurring. Ensuring that wiring is protected from wear and tear will also extend the life of your ACC system.
What is C05CE?
The diagnostic trouble code (DTC) C05CE is associated with the vehicle's advanced driver-assistance systems (ADAS), particularly relating to issues with the Adaptive Cruise Control (ACC) or other similar features. When this code is triggered, it indicates a malfunction in the communication between the vehicle's control modules, which can lead to the ACC system not functioning correctly. For example, in 2016-2020 Ford Explorers, this code might relate to sensor faults or wiring issues that affect how the vehicle interprets speed and distance, potentially leading to dangerous situations during highway driving. It’s important to note that while the engine may still run normally, the failure of such systems can compromise overall safety. In practical terms, this means that drivers may notice that their cruise control doesn’t engage, or it may disengage unexpectedly. If left unaddressed, it could lead to more significant repairs down the line, making it crucial to diagnose and resolve the issue promptly.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C05CE is present:
- Check engine light remains illuminated, indicating a fault in the ACC system and requiring immediate attention.
- Adaptive Cruise Control fails to engage, leading to potential safety risks during highway driving.
- Intermittent disengagement of cruise control while driving, which can be alarming and may require manual speed control.
- Noticeable decrease in fuel efficiency due to improper speed management when cruise control is malfunctioning.
- Warning messages on the dashboard related to the ACC or braking systems, suggesting further diagnostics are needed.
Possible Causes
Most common causes of C05CE (ordered by frequency):
- Faulty radar or camera sensors are the most common cause, contributing to about 60% of C05CE cases; these sensors may be misaligned or damaged.
- Wiring issues in the ACC system can also trigger this code, often due to wear from exposure to the elements or improper installation.
- Software glitches in the vehicle's control module can lead to false readings, and regular updates can help prevent this issue.
- Less common, but serious causes include malfunctions in the main control module which could require complete replacement.
- Rarely, environmental factors like heavy rain or fog can obstruct sensors, causing temporary faults that trigger the C05CE.
