Note. The sensor sends information about the pressure in the brake master cylinder to the ECU.
Removing
Place the car on a lift.
Install a pressurizer on the brake pedal to prevent leakage of brake fluid.
Attention! Take measures to collect the brake fluid to prevent damage to parts and bodywork in the area of the elements.
Remove the air pipe and expansion tank.
It is necessary to pre-fill the new sensor with brake fluid using a syringe to avoid the slightest infiltration of air into the system. Note: When filling is complete, the brake fluid should form a dome at the sensor inlet.
Using a rag, remove the pressure sensor and replace it with a new one immediately.
