The radar sensor for Honda Sensing in the 2019 Accord is mounted behind the front bumper, centered along the lower grille area, and is not visible without removing panels. It works with the camera to enable adaptive cruise control and collision mitigation.
Understanding Honda Sensing radar hardware
Honda’s forward-looking radar operates at 77 GHz and works with a windshield-mounted camera to deliver features such as Adaptive Cruise Control (ACC), Collision Mitigation Braking System (CMBS), and Lane Keeping Assist. The radar’s placement is designed to sense traffic ahead while minimizing damage from road debris.
Where to find it on a 2019 Accord
In most 2019 Accords equipped with Honda Sensing, the radar module sits behind the front bumper cover, centered beneath the lower grille opening. It resides in a recessed housing integrated into the bumper, with the sensor facing forward. Access for servicing typically requires removing the lower fascia.
For those investigating or performing basic checks, these points summarize the sensor’s location and access considerations.
- Center-front of the vehicle, behind the lower bumper cover and grille opening.
- Mounted in a recessed housing that aligns with the bumper centerline. It is not visible from above unless the bumper cover is removed.
- Access for servicing typically requires removing the lower fascia or bumper cover according to the service manual.
These placement details help explain why you might not see the radar sensor without removing panels, and why service manuals emphasize careful alignment after any bumper work.
Exact positioning details
The radar sensor is positioned behind the front bumper’s lower grille opening, near the vehicle’s centerline. The corresponding forward camera is mounted high on the windshield near the rearview mirror, and both components feed data to the collision-avoidance system.
What to know if you’re diagnosing or replacing it
Because the radar sensor is sensitive to alignment and debris, issues with Honda Sensing features can stem from misalignment, bumper removal, or debris buildup behind the bumper. Do not tamper with the sensor housing or wiring unless you have the proper tools and procedure.
If servicing is needed, technicians will recalibrate and realign the sensor and camera using diagnostic tools to ensure safety features function correctly.
Summary
The radar sensor on a 2019 Honda Accord is located behind the front bumper in a center-mounted housing beneath the lower grille. It works with the front-facing camera to enable Honda Sensing features like Adaptive Cruise Control and Collision Mitigation Braking. Proper care and calibration are essential when servicing this area.
