Code C100E Mercury Description

The C100E diagnostic trouble code (DTC) specifically relates to the Brake Pedal Angle Sensor Circuit 2 in a Mercury vehicle. This code indicates that there is an issue with the sensor responsible for detecting the angle of the brake pedal. The brake pedal angle sensor plays a crucial role in the vehicle's braking system by providing input to the electronic control unit (ECU) to help determine the driver's braking intentions and apply the appropriate amount of braking force.
