Where is the collision sensor in a Honda CRV?

The collision-sensing hardware in most Honda CR-Vs sits mainly in two places: a forward-looking radar unit tucked into the center of the front bumper and a camera mounted behind the windshield near the rear-view mirror. The exact arrangement can vary by model year and trim, but these are the core components powering Honda Sensing’s collision-related features.

How the system detects collisions

Honda Sensing monitors the road ahead using a radar sensor plus a camera to assess distance, speed, and potential obstacles. These sensors work together to trigger warnings and, if needed, braking. Some trims also include ultrasonic sensors for parking assistance, and the vehicle has dedicated crash sensors to manage airbag deployment.

Primary sensors and their locations

The main collision-related sensors are located in two areas of the vehicle.

• Forward radar sensor: Typically mounted behind the center of the front bumper or in the lower front grille area, facing forward to detect distance and relative speed to obstacles.


• Front camera: Usually positioned behind the windshield, near the top center behind the rear-view mirror, to identify lanes, pedestrians, and other hazards.


• Ultrasonic sensing (where equipped): Located in the front and rear bumper corners to assist with parking and close-quarters sensing, supporting but not replacing the primary collision systems.

Together, the radar and camera form the core of the collision warning and mitigation system (FCW/CMBS). Ultrasonic sensors add supplementary data for parking-related safety, and the vehicle’s crash sensors handle airbag deployment in the event of a collision.

Model-year variations

Exact sensor placement can shift slightly between generations and trims, but the general layout remains consistent across recent CR-V models. Some newer configurations also include Honda Sensing 360, which adds extra sensing coverage around the vehicle.

CR-V (2017–2022)

For these generations, the forward collision system relies on a radar sensor located behind the center of the front bumper or in the lower grille, paired with a camera mounted behind the windshield near the rear-view mirror.

CR-V (2023–present)

Newer CR-Vs continue to use a front radar sensor in the bumper and a windshield-mounted camera, with potential updates in sensor technology and software. Trims equipped with Honda Sensing 360 may add additional side and rear sensing elements, but the primary forward collision sensing remains the radar–camera pair.

What to do if collision sensing isn’t working

If you notice warning lights, unexpected braking, or advisory messages related to Honda Sensing, don’t drive aggressively. Have the system inspected promptly at a Honda service center. In the meantime, you can perform these basic checks before a diagnostic:

• Check for visible bumper damage or debris that could obstruct the sensors’ field of view.


• Ensure the windshield and camera area behind the rear-view mirror are clean and free of obstructions or cracks that could affect camera performance.


• Inspect related fuses or disconnects as outlined in the owner’s manual; a blown fuse can disable the system.


• Schedule a diagnostic with a qualified technician who can read fault codes from the Honda Sensing system using factory tools.

Note: A malfunctioning collision-sensing system reduces the effectiveness of warnings and automated braking. Professional inspection is essential to restore full safety functionality.

Summary

In a Honda CR-V, the collision sensor setup centers on a forward radar unit in the front bumper and a camera behind the windshield, forming the core of Honda Sensing’s collision warning and mitigation capabilities. Some models add ultrasonic sensors and optional 360-degree sensing configurations. The exact placement can vary by year and trim, so consult your owner’s manual or a dealer for model-specific details. Regular cleaning of sensor areas and prompt service of any warning lights help maintain optimal performance.

What is the problem with the collision mitigation system on a Honda CRV?

Honda CR-V collision mitigation system problems can stem from dirty sensors, misaligned cameras, a weak battery, or faulty radar units, and they often present as unexpected braking, false warnings, or a complete system failure. To troubleshoot, start by cleaning the front camera lens and radar sensor on the grille, and ensure the battery is in good condition. If the issue persists, a dealer may need to perform a sensor recalibration or a software update, as some problems are addressed by technical service bulletins (TSBs).
 
Common problems

• False activation: The system may activate the brakes or show warnings when there is no obstacle, sometimes triggered by everyday road conditions like shadows or bumps. 
• Failure to activate: In other cases, the system may fail to intervene when a collision is imminent. 
• Warning lights: You may see warning lights for the collision mitigation system, the road departure mitigation system, or other driver-assist features. 
• Inconsistent performance: The system's behavior can be spotty and unpredictable. 

What you can do

• Clean the sensors: A dirty front camera lens (behind the windshield) or radar sensor (in the front grille) is a common cause of problems. Gently clean both areas with a microfiber cloth. 
• Check the battery: A weak or failing battery can cause a host of electronic issues, including problems with the CMBS. 
• Adjust settings: Park the vehicle, turn the ignition on, and navigate to the Driver Assist System Setup menu to check or adjust the forward collision warning distance in the settings. 
• Consult the manual: Refer to your owner's manual for specific instructions on your model year. 

When to see a dealer

• If the problem continues after cleaning the sensors, take the vehicle to the dealership.
• The dealer can perform a diagnostic scan to identify specific sensor issues or misalignment.
• They may need to recalibrate the sensors or update the software, as some issues are addressed by technical service bulletins (TSBs).
