What is C0195?
The diagnostic trouble code (DTC) C0195 indicates a fault in the brake pressure sensor circuit, specifically in models like the 2010-2015 Chevrolet Equinox and GMC Terrain. This code signifies that the vehicle's electronic stability control (ESC) system has detected an abnormal signal from the brake pressure sensor, which could lead to compromised braking performance. The brake pressure sensor is vital for monitoring the hydraulic pressure in the braking system and providing accurate data to the vehicle's onboard computer. When this code is triggered, it means that the sensor is either malfunctioning or there is an issue with the wiring or connections. This can result in the activation of the brake warning light on the dashboard, and in some cases, the stability control system may disable itself as a safety precaution. Understanding this code is crucial because it impacts the vehicle's braking efficiency and overall safety. Drivers experiencing this code should not ignore the warning, as it can lead to serious consequences if the braking system fails while driving. Addressing C0195 promptly ensures that the vehicle remains safe and reliable on the road.
System: C - Chassis (ABS, Steering, Suspension)
Symptoms
Common symptoms when C0195 is present:
- The brake warning light illuminates on the dashboard, signaling a potential issue with the braking system.
- Drivers may notice a decrease in braking effectiveness, leading to longer stopping distances, which can be dangerous.
- Unusual noises, like grinding or squeaking, may occur when applying the brakes, indicating potential mechanical issues.
- The vehicle may experience stability control malfunctions, causing it to handle poorly in slippery conditions.
- In some cases, the anti-lock braking system (ABS) light may also activate, indicating further issues with the braking system.
Possible Causes
Most common causes of C0195 (ordered by frequency):
- The most common cause of C0195 is a faulty brake pressure sensor, which has a likelihood of about 60%. This sensor can fail due to wear and tear over time.
- A second common cause is damaged wiring or poor connections in the brake pressure sensor circuit, affecting the sensor's ability to communicate with the vehicle's computer.
- Third, low brake fluid levels or contaminated brake fluid can lead to sensor malfunctions. Regularly checking and maintaining brake fluid can help prevent this issue.
- Less common but serious causes include internal brake system failures that could lead to hydraulic leaks, compromising braking performance.
- A rare cause might be software glitches in the vehicle's ECU, which can sometimes lead to erroneous fault codes appearing.
