Brake Fluid Pressure Sensor
WARNING: This page is about a different car, the 2013 Acura MDX, 2012 Acura MDX, 2011 Acura MDX, and 2010 Acura MDX. However, it is still accessible from the selected car via links, so may be relevant.
The brake fluid pressure sensors are installed in the right and left sides of the brake line 4-way joint. The brake fluid pressure is converted to a signal (voltage value) and is output to the ACC unit. The ACC unit is always monitoring the ACC brake operation and the brake pressure controlled by the signals sent from the brake fluid pressure sensors.
