C1234 Scion Code - Yaw Rate Sensor Malfunction
Quick Answer
The skid control Electronic Control Unit (ECU) receives signals from the Yaw Rate and Deceleration sensor via the CAN communication system. Common causes include Faulty Yaw Rate and Deceleration Sensor, Yaw Rate and Deceleration Sensor harness is open or shorted, Yaw Rate and Deceleration 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.
