 Master Cylinder Pressure Sensor (C1246,C1281,C1364)

DESCRIPTION The regulator pressure sensor and wheel cylinder pressure sensor are built into the brake actuator. They measure their respective pressures and send signals to the skid control ECU (brake booster with master cylinder assembly). DTC C1281 will be cleared when the regulator pressure sensor
