What is a Brake Pressure Sensor?
A Brake Pressure Sensor is an essential component found in most modern vehicles equipped with dynamic stability control. This sensor gauges the precise level of braking force applied by the driver. The measurement is utilized by the dynamic vehicle control system to address disparities between the driver’s intended braking actions and the vehicle’s actual response.
The dynamic stability system incorporates various sensors to monitor wheel speed, body roll, rotation rate, acceleration, deceleration, steering input, and traction to the road. This information enables the system to use the Anti-Lock Braking System (ABS) pump for timely adjustments to pressure on each wheel. This adaptive process aims to maintain stability and safety, especially in challenging driving conditions such as high-speed turns or emergency braking situations where the vehicle might start to fishtail.
In contemporary vehicles, the brake pressure sensor is typically integrated into the ABS pump and cannot be replaced separately.
Common Brake Pressure Sensor Failures
Brake Pressure Sensor failures are prevalent in vehicles equipped with the ATE MK60 ABS system, widely used by various manufacturers from around 2002 to 2015.
Diagnosing and Addressing a Faulty Internal Brake Pressure Sensor
To diagnose a faulty sensor, professional diagnostic equipment is required to access the vehicle’s ABS system through the diagnostic port. Checking for stored fault codes is the initial step. If a code related to ‘brake pressure sensor malfunction’ appears, attempts to clear the code should be made. If the issue persists, examining live data, specifically the ‘brake pressure’ value, can reveal anomalies. A constant maximum pressure reading, even with no pressure on the pedal, indicates a malfunctioning internal brake pressure sensor.
