What is C0728?
The Diagnostic Trouble Code (DTC) C0728 indicates a fault within the Anti-lock Braking System (ABS), specifically related to the acceleration sensor. This code is prevalent in various makes and models, particularly the 2015-2018 Ford Explorer. The acceleration sensor is crucial for your vehicle's stability control, helping to prevent wheel lock-up during braking. When this sensor fails or sends incorrect signals, it can affect the ABS operation, leading to decreased braking performance and potential safety hazards. Car owners might notice their ABS warning light illuminating on the dashboard. Additionally, the vehicle may experience erratic braking behavior, such as the brakes engaging unexpectedly or a lack of response when applying the brakes. Ignoring this code can lead to serious brake issues, increasing the risk of accidents. Therefore, understanding and addressing DTC C0728 promptly is essential for maintaining your vehicle's safety and performance.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0728 is present:
- The ABS warning light remains illuminated on the dashboard, indicating a malfunction within the braking system.
- Drivers may experience a pulsing sensation in the brake pedal during hard braking, suggesting the ABS system is not functioning correctly.
- Fuel economy may decrease by 10-15% due to the vehicle's improper braking system affecting overall performance.
- Unexpected brake engagement may occur, leading to a sudden stop, which can be dangerous while driving.
- In some cases, the vehicle may enter 'limp mode,' limiting speed and performance until the issue is resolved.
Possible Causes
Most common causes of C0728 (ordered by frequency):
- The most common cause of DTC C0728 is a faulty acceleration sensor, which has a likelihood of approximately 60%. This sensor may malfunction due to wear and tear or exposure to moisture.
- Another cause could be damaged wiring or connectors related to the sensor, often due to corrosion or physical damage. This issue accounts for around 20% of cases.
- In some instances, a software glitch in the ABS control module may lead to this code. Keeping your vehicle's software updated can help prevent this issue.
- Less common but serious causes include a failing ABS control module, which can lead to complete brake failure if not addressed. This scenario is rare but requires immediate attention.
- A rare cause could be a manufacturing defect in the sensor, which may need a complete replacement if under warranty.
