Code C1822 Mercury Description

The diagnostic trouble code C1822 for Mercury vehicles indicates an Electronic Parking Brake Sensor Electrical Failure. This code refers to a malfunction in the electronic parking brake system's sensor, which is responsible for detecting the position and status of the parking brake. The electronic parking brake system is a modern feature that replaces the traditional handbrake lever with a button or switch. When this sensor fails, it can lead to issues with engaging or disengaging the parking brake, affecting the vehicle's ability to secure itself when parked.
