What is C0328?

DTC C0328 indicates a problem with the traction control system, specifically a malfunction related to the brake pressure sensor circuit. This diagnostic trouble code is commonly found in vehicles like the 2010-2015 Chevrolet Silverado and GMC Sierra. When the stability control system detects an issue with the brake pressure sensor, it triggers this code. In practical terms, this means the traction control may not function properly, which can lead to reduced vehicle stability, especially in slippery conditions. Drivers may notice the traction control warning light illuminated on the dashboard. The vehicle may also exhibit erratic behavior during acceleration or braking, which can compromise safety. It is crucial to address this issue promptly, as ignoring it could lead to more severe problems, including compromised braking performance. The brake pressure sensor plays a vital role in determining the amount of force applied to the brakes and how much traction is available. If the sensor fails, the vehicle may not respond appropriately to driver inputs, leading to potential accidents. Understanding this code is essential for maintaining vehicle safety and performance.

System: C - Chassis (ABS, Steering, Suspension)

Symptoms

Common symptoms when C0328 is present:

  • The traction control light remains illuminated, indicating a malfunction in the system.
  • You may experience the vehicle losing traction during acceleration, particularly on wet or icy surfaces.
  • The braking system may feel unresponsive or inconsistent, making it difficult to stop safely.
  • There may be a noticeable decrease in fuel economy due to erratic throttle responses.
  • The check engine light may also be activated, suggesting additional diagnostic codes could be present.

Possible Causes

Most common causes of C0328 (ordered by frequency):

  1. The most common cause of C0328 is a faulty brake pressure sensor, with a likelihood of around 70%. This sensor can fail due to wear and tear or electrical issues.
  2. Another potential cause could be damaged wiring in the brake pressure sensor circuit, often resulting from exposure to moisture or road debris.
  3. A third cause might be a malfunctioning ABS module, which could prevent proper communication between the traction control system and the brake pressure sensor.
  4. Less common but serious could be a failure in the vehicle's stability control system, which may require a more extensive diagnostic process.
  5. Rarely, this code may be triggered by software issues in the vehicle’s control modules that may require programming or updates.
