what does it mean if my Toyota Camry XV70 (2018-2024) has a C1201 code?

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, socket set, torque wrench
• Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Address Brake Fluid Level

• Open the hood and locate the brake fluid reservoir.
• Check the fluid level; if low, refill with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
• Close the reservoir cap securely.

3. Replace Brake Pressure Sensor (if necessary)

• Disconnect the battery to prevent electrical shorts.
• Locate the brake pressure sensor; it is typically mounted on the master cylinder or brake line.
• Remove the electrical connector from the sensor.
• Unscrew the sensor using the appropriate socket.
• Install the new brake pressure sensor and tighten to the manufacturer’s specifications (usually around 10 Nm).
• Reconnect the electrical connector.

4. Inspect and Repair Wiring (if necessary)

• Trace the wiring from the brake pressure sensor and actuator.
• Repair or replace any damaged wires or connectors found during inspection.
• Ensure all connections are secure and free of corrosion.

5. Clear Error Codes

• Reconnect the battery and use the OBD-II scanner to clear the C1201 code.
• Verify that the code does not reappear after performing repairs.
