The sensors may not work properly if dust, dirt, snow, or even oil gathers. Grime or debris is the usual reason why the sensors fail. In some cases, the backup sensor will send an error code.
If the sensors aren’t reacting properly then place your ear to the sensor when you’re in reverse (be sure to keep your foot on the brake). You should be able to hear a buzzing sound. If there is no sound your sensor probably needs to be replaced.
Why is my car not beeping when I back up?
Sensor Not Making A Beeping Sound
To avoid this problem, you need to assess your sensors. The sensors may have accumulated dirt, making them unable to detect the nearby object. Aside from dirt, snow, dust, and engine oil can also block the sensors. Use a clean rag to wipe the sensors.

What is the difference between parking assist and parking sensors?
Park assist normally will only make a sound and/or show an image to tell the driver the distance to an object. Whereas active park assist will tap into other vehicle systems to physically park the vehicle. Normally, additional sensors are located in the sides of the bumper or in the fender.
Parking Sensors are mounted in the front and/or rear car bumper. Parking sensors detect obstacles when you’re maneuvering at slow speeds, like parking for example.
How much does it cost to fix a park assist sensor?
