Code C1103 Description

The C1103 code refers to an issue with the front right sensor 1 in the vehicle's braking system. This sensor is responsible for monitoring the speed of the front right wheel and sending this information to the vehicle's electronic control unit (ECU). When this sensor detects an issue or malfunctions, it can affect the vehicle's overall performance, particularly in terms of braking efficiency and stability. This code indicates a potential problem with the sensor's signal or circuit, which can lead to inaccurate speed readings and impact the vehicle's ABS (anti-lock braking system) and traction control systems.
