What is C0A62?
The diagnostic trouble code (DTC) C0A62 indicates a problem with the vehicle's adaptive cruise control system, specifically related to the front radar sensor malfunctioning or losing communication with the vehicle's onboard computer. This code is commonly found in 2015-2021 Ford and Lincoln models, including the Ford F-150, Ford Explorer, and Lincoln MKZ. When this code is triggered, it means that the system responsible for maintaining a set speed and distance from the vehicle ahead is unable to function properly. This could lead to diminished safety features, as the adaptive cruise control relies on accurate readings from the radar sensor to adjust speed accordingly. In real-world scenarios, drivers might notice that their adaptive cruise control is not engaging, or they may see warning lights on their dashboard indicating a problem. Ignoring this code can result in reduced driving comfort and potential safety risks, making it crucial for vehicle owners to address it promptly to ensure their adaptive systems operate effectively.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0A62 is present:
- The adaptive cruise control feature fails to activate, leaving drivers without this convenience and safety feature.
- Dashboard warning lights illuminate, specifically the adaptive cruise control indicator, indicating an issue that requires attention.
- Drivers may notice erratic cruise control behavior, such as sudden disengagement or failure to maintain set speed.
- The vehicle may experience a decrease in overall fuel efficiency due to manual acceleration adjustments.
- In some cases, the system may throw additional codes related to other components, complicating diagnostics.
Possible Causes
Most common causes of C0A62 (ordered by frequency):
- The most common cause of the C0A62 code is a faulty front radar sensor, which is often responsible for detecting vehicles and obstacles ahead. This has a likelihood of about 60%.
- Another potential cause could be damaged wiring or connectors related to the radar sensor. Issues such as frayed wires or corrosion can disrupt communication, with a likelihood of about 20%.
- Improper calibration of the radar sensor following a collision or service can cause this code to trigger. Regular checks post-repair can help prevent this.
- Less common causes may include software glitches within the vehicle's computer system, which could necessitate a software update.
- Rarely, environmental factors such as heavy rain, fog, or snow may temporarily affect sensor performance, leading to a false C0A62 code.
