DTC C0573-2A: Brake Pressure Sensor "C" Signal Stuck In Range [11/2021 - ]: Description
WARNING: This page is about a different car, the 2025 Lexus NX 350h, 2024 Lexus NX 350h, 2023 Lexus NX 350h, and 2022 Lexus NX 350h. However, it is still accessible from the selected car via links, so may be relevant.
The accumulator pressure sensor is built into the brake booster with master cylinder assembly and detects the accumulator pressure.
If the No. 1 skid control ECU (brake booster with master cylinder assembly) detects that the accumulator pressure sensor value is below the threshold, operation of the motor relay is requested and the pump motor built into the brake booster with accumulator pump assembly operates.
