C1440 Toyota Code - Steering Angle Sensor Unusual Bank Angle Detected
Quick Answer
If the Skid Control ECU (Brake Actuator Assembly) determines that the vehicle is being driven at a steep bank angle, the Skid Control ECU (Brake Actuator Assembly) stores Diagnostic Trouble Code (DTC) C1440 while VSC operation is temporarily disabled. Common causes include Faulty Yaw Rate and Acceleration Sensor (Airbag Sensor Assembly), Yaw Rate and Acceleration Sensor harness is open or shorted, Yaw Rate and Acceleration Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
