DTC C0288 is frequently reported in vehicles like the 2010-2018 Chevrolet Equinox and the 2012-2016 GMC Terrain, among others. Check for recalls or technical service bulletins for your specific model.

How can I prevent C0288 from happening again?

Regular maintenance checks on your brake system, including inspecting the brake fluid and wiring, can help prevent issues. Also, be mindful of any warning lights and address them promptly.

What is C0288?

DTC C0288 indicates a problem with the brake pressure sensor circuit, specifically relating to its range or performance. This code is commonly found in vehicles equipped with advanced braking systems, such as anti-lock brakes (ABS) and electronic stability control (ESC). When the brake pressure sensor fails to provide accurate data, it can lead to improper brake function, which may significantly affect vehicle safety. Symptoms might include an illuminated check engine light, unusual braking behavior, or even the activation of the ABS or traction control warning lights. If you drive a vehicle like the 2010-2018 Chevrolet Equinox or the 2012-2016 GMC Terrain, you may encounter this code more frequently. Ignoring DTC C0288 can lead to reduced braking efficiency, which could result in unsafe driving conditions. Therefore, addressing this issue promptly is crucial for maintaining the overall safety and performance of your vehicle.

Symptoms

Common symptoms when C0288 is present:

  • The check engine light is illuminated, indicating a fault that needs attention.
  • The brake pedal feels unusually soft or hard, affecting driver confidence during braking.
  • The ABS warning light remains on, suggesting issues with the anti-lock braking system.
  • Increased stopping distances observed, which can be dangerous in emergency situations.
  • The vehicle may experience erratic braking behavior, leading to potential loss of control.

Possible Causes

Most common causes of C0288 (ordered by frequency):

  1. The most common cause of DTC C0288 is a faulty brake pressure sensor, occurring in about 60% of cases. This sensor may fail due to wear and tear or moisture exposure.
  2. Another frequent cause is damaged wiring or poor connections in the brake pressure sensor circuit, which can impede accurate readings.
  3. A third cause can be the ABS module malfunctioning, where the control unit may fail to interpret the sensor signals correctly. Regular system checks can help prevent this.
  4. Less commonly, a brake fluid leak may create pressure inconsistencies, contributing to this code. Ensure regular brake fluid checks to avoid this issue.
  5. A rare but possible cause includes software issues within the vehicle’s control module, which may require an update to resolve.
