Where is the Toyota pre-collision sensor?
The Toyota pre-collision sensor is typically located behind the front grille or bumper of the vehicle, near the center of the front end. This sensor is a key component of Toyota's pre-collision safety system, which is designed to detect potential collisions and automatically apply the brakes to help avoid or mitigate the impact.
Understanding the Toyota Pre-Collision Sensor
The Toyota pre-collision sensor is a radar-based system that uses a forward-facing camera and radar unit to continuously monitor the road ahead. The sensor is able to detect the presence of vehicles, pedestrians, and other obstacles in the vehicle's path, and can trigger the pre-collision safety system if it determines that a collision is imminent.
When the pre-collision sensor detects a potential collision, it can take several actions to help avoid or reduce the impact:
- Provide a visual and audible warning to the driver to alert them of the impending collision
- Automatically apply the brakes to slow the vehicle and reduce the force of the impact
- Tighten the seatbelts to help secure the occupants in their seats
- Activate other safety systems, such as the airbags, to further protect the occupants
The pre-collision sensor is an important part of Toyota's comprehensive safety suite, which also includes features like lane departure warning, adaptive cruise control, and blind spot monitoring.
Locating the Pre-Collision Sensor
The exact location of the Toyota pre-collision sensor can vary depending on the specific model and year of the vehicle. However, in most cases, the sensor is located behind the front grille or bumper, near the center of the front end of the vehicle. This placement allows the sensor to have a clear view of the road ahead and effectively detect potential obstacles.
It's important to note that the pre-collision sensor is a delicate component and should be handled with care. If the sensor is damaged or obstructed, it may not function properly, which could compromise the effectiveness of the pre-collision safety system. Regular maintenance and inspection of the sensor is recommended to ensure it is working correctly.
Where is the pre-collision sensor located in a Toyota RAV4?
The RAV4's pre-collision sensor system uses two main components: a radar sensor, typically located behind the front Toyota emblem on the grille, and a front camera located behind the windshield near the rearview mirror. Both must be clean and free of obstructions, like dirt, snow, or stickers, for the system to function correctly.

Radar sensor
- Location: Behind the front grille, often concealed by the Toyota emblem.
- Function: Uses millimeter-wave radar to detect large objects like other vehicles.
- Maintenance: Keep the area around the emblem clean by wiping it with a soft cloth. Do not attach any stickers or accessories to this area.

Front camera
- Location: On the windshield, near the top and behind the rearview mirror.
- Function: Detects pedestrians, bicycles, and lane markings.
- Maintenance: Keep the area of the windshield in front of the camera clear of condensation, ice, or other obstructions. Use the defroster if needed.

Troubleshooting
- If you see a pre-collision system warning, first check both the radar sensor area and the front camera area of the windshield for any dirt or obstructions.
- Clean both areas with a soft cloth.
- If the warning persists, have the system inspected by a dealer, as it could indicate a more serious issue.
Where is the pre-collision sensor located?
The pre-collision assist sensor is typically located in one of two places: a radar sensor behind the front bumper/grille and a camera near the rearview mirror on the windshield. The radar sensor is often in the center of the lower grille, behind a fascia cover. The system relies on both sensors, so it's important to keep both the front grille area and the windshield area in front of the camera clean.

Why did my pre-collision light come on my Toyota?
This is letting you know that your Pre-Collision System (PCS) is currently disabled. This could be from something blocking the cameras behind your rear view mirror (in that big black box against the windshield) or a damaged or covered radar sensor (behind the Toyota badge on the front grille).
