What this part does

The Lane Departure Warning Sensor is typically mounted behind the rearview mirror, looking out through the windshield. It actively monitors road lines and physical boundaries to calculate the vehicle's position within the lane. It sends data to the driver assistance module to trigger alerts or steering corrections if the car begins to drift. If this sensor fails, the lane departure warning and lane keep assist systems will disable, usually triggering an immediate warning message on the instrument cluster.

Before you order

• This Lane Departure Warning Sensor requires professional calibration using Mazda diagnostic software after installation. It will not function as a plug-and-play unit.
• Verify that the mounting bracket on your windshield is perfectly intact and not bent. The camera requires highly precise physical alignment to operate safely.
• Ensure the section of the windshield directly in front of the camera lens is free of cracks, deep pitting, or aftermarket tint, as visual obstructions will cause calibration to fail.
