Code C1173 Description

The C1173 diagnostic trouble code (DTC) indicates a Steering Angle Sensor Plausibility Error. This code is typically associated with an issue in the steering angle sensor, which is a crucial component of the vehicle's stability control system. The steering angle sensor is responsible for measuring the steering wheel's position and rate of rotation, providing important data to the vehicle's electronic stability control (ESC) system to help maintain control during sudden maneuvers or slippery road conditions.
