Code C1955 Description

The C1955 code indicates a problem with the steering angle sensor circuit, specifically that it is open. The steering angle sensor is a crucial component of the vehicle's stability control system, as it provides information on the steering wheel position and angle to the vehicle's computer. This information is used to determine the vehicle's direction and stability, aiding in functions such as traction control and electronic stability control. When the steering angle sensor circuit is open, it means that there is a break or disconnection in the circuit, preventing the sensor from sending accurate data to the vehicle's computer. This can result in a loss of stability control, potentially leading to unsafe driving conditions.
