C1271 Scion Code - Low Output Signal of Front Right Speed Sensor
Quick Answer
The speed sensor detects the wheel speed and sends the appropriate signals to the Skid Control ECU (Brake Actuator Assembly). Common causes include Faulty Front Speed Sensor Right, Front Speed Sensor Right Rotor (Front Axle Hub Sub-Assembly Right), Front Speed Sensor Right harness is open or shorted. 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.
