C1143 on a Nissan vehicle refers to a fault in the Steering Angle Sensor Circuit. This diagnostic trouble code is triggered when the ABS control module detects an abnormal or no signal from the steering angle sensor, which is crucial for stability and traction control systems.

The steering angle sensor monitors the position and rotation of the steering wheel and relays this data to the vehicle’s onboard computer to help determine the intended direction of travel. If the circuit is faulty due to wiring issues, sensor failure, or poor connections, it can lead to warning lights on the dashboard, such as the ABS or VDC (Vehicle Dynamic Control) indicators.
