Code C200B Mercury Description

The C200B code for Mercury vehicles specifically refers to an issue with the Steering Shaft Torque Sensor 1. This sensor is a crucial component of the vehicle's power steering system, responsible for detecting the amount of torque applied to the steering wheel by the driver. The sensor sends this information to the vehicle's electronic control unit (ECU), which then adjusts the power steering assistance accordingly to provide a smoother and more responsive steering experience.
