What is C0164?

DTC C0164 is a diagnostic trouble code that indicates a malfunction in the brake system, specifically related to the brake pressure sensor or its circuit. This code is most frequently encountered in vehicles such as the 2013-2017 Chevrolet Silverado and GMC Sierra, where it can lead to significant braking issues if not addressed promptly. The brake pressure sensor is crucial for monitoring the hydraulic pressure in the brake system, ensuring that the brakes function effectively. If the sensor fails or if there’s an issue within the circuit, it can result in erratic brake performance. Symptoms may include a warning light on the dashboard, reduced braking efficiency, or even a complete loss of braking function in extreme cases. Ignoring this code can lead to unsafe driving conditions, making it essential for car owners to address the issue quickly. Proper diagnosis often requires specialized tools like the GeekOBD APP, which can provide real-time data and assist in pinpointing the exact cause of the malfunction. In summary, if your vehicle is displaying DTC C0164, thorough investigation and timely repair are critical to ensure safety on the road.

Symptoms

Common symptoms when C0164 is present:

  • The check engine light or ABS warning light stays illuminated, indicating a problem with the braking system.
  • Braking performance is noticeably reduced, leading to longer stopping distances and a spongy brake pedal feel.
  • The brake system may engage erratically, causing the vehicle to lurch or hesitate when applying the brakes.
  • Unusual noises such as grinding or squealing may be present when braking, signaling potential brake component wear.
  • In severe cases, you may experience complete brake failure, making immediate repairs essential.

Possible Causes

Most common causes of C0164 (ordered by frequency):

  1. The most common cause of DTC C0164 is a faulty brake pressure sensor, which has a likelihood of about 60%. This can occur due to wear and tear or exposure to moisture.
  2. A short or open circuit in the wiring that connects the brake pressure sensor can also trigger this code, accounting for 25% of cases. Inspecting and repairing damaged wires is crucial.
  3. Corrosion at the sensor connector is another potential cause, which can be prevented by regularly checking and cleaning connections to avoid moisture buildup, representing around 10% of cases.
  4. Less common but serious causes include internal brake system failures, such as a failing master cylinder, which can lead to catastrophic brake failure and should be diagnosed immediately.
  5. A rare cause might be software issues in the vehicle’s ABS module, which can misinterpret sensor readings, though this is less frequently encountered.
