Regularly inspect the ABS system during maintenance, ensure connectors are clean and secure, and avoid driving over rough terrain that could damage the sensors.
What is C0287?
The diagnostic trouble code (DTC) C0287 indicates an issue with the ABS (Anti-lock Braking System) sensor, specifically relating to the wheel speed sensor circuit. This code typically appears when the vehicle's onboard diagnostic system detects an abnormal reading from the wheel speed sensors, which are crucial for the correct functioning of the ABS. When the ABS system detects that the wheel speed sensor signal is out of range or inconsistent, it triggers the C0287 code. This can lead to several issues including the potential failure of the ABS system, which is designed to prevent wheel lockup during braking, promoting vehicle stability and control. If this issue is not addressed, drivers may experience reduced braking efficiency, increased stopping distances, and the possibility of the ABS warning light illuminating on the dashboard. It’s important to note that vehicles equipped with advanced safety systems may also be affected, leading to further complications in safety features like traction control. Therefore, understanding the implications of this code is crucial for maintaining vehicle safety and performance.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0287 is present:
- The ABS warning light illuminates on the dashboard, indicating a malfunction within the braking system.
- The brakes may feel less responsive than usual, causing concern during emergency stops or sudden braking.
- You might notice that the traction control warning light is also activated, suggesting that the ABS system is compromised.
- In some cases, the vehicle may experience unintended wheel locking or skidding during braking, especially on slippery surfaces.
- You may also see a decrease in fuel efficiency, as the vehicle's systems struggle to compensate for the faulty ABS sensor.
Possible Causes
Most common causes of C0287 (ordered by frequency):
- The most common cause is a faulty wheel speed sensor, which is responsible for sending speed data to the ABS module. This occurs in about 70% of cases.
- Another possible cause is damaged wiring or connectors within the ABS system, leading to signal disruptions.
- A malfunctioning ABS control module can also trigger this code, though this is less common. Regular maintenance checks can help prevent such issues.
- In rare cases, contamination or physical damage to the sensor due to road debris can occur, affecting performance.
- Additionally, issues with the vehicle’s power supply or ground connections may lead to intermittent faults in the ABS system.
