C1514 Code - Torque Sensor Power Supply Voltage Malfunction
Quick Answer
The torque sensor converts the rotation torque input from the steering wheel into electric signals and sends them to the Power Steering ECU. Common causes include Faulty Torque Sensor (built into steering column assembly), Torque Sensor harness is open or shorted, Torque 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.
