Parking Sensors

What are parking sensors

One of the more challenging aspects of driving is knowing exactly where your vehicle begins and ends. This is particularly important when parking or reversing out of tight parking spots. Luckily, many vehicles are now equipped with parking assist systems. These parking sensor systems are especially useful for vehicles that are higher off the ground, since the height can make it hard to see the curb.  Parking sensors also come in handy for new drivers that aren't yet familiar with the exterior dimensions of their vehicle. 

Parking sensors (also known as proximity sensors, back-up sensors, or reverse sensors) mount in the rear bumper itself and use ultrasonic technology to "see" objects as they come closer to the vehicle. Some parking assist systems use four proximity sensors, and others use up to six or even more. They usually emit a beeping sound inside the vehicle that increases in speed as the object becomes closer. When a collision is imminent, the beeping becomes one solid, terribly ominous tone. Many vehicles also have a visual aspect of the parking assist system as well, where there are a series of lights that turn on as the obstacle gets closer. When the collision becomes imminent, these lights typically all begin flashing.

How do I know if my parking sensors need to be replaced?

Parking sensors can malfunction in a number of different ways. The most obvious sign of a faulty sensor is a failure to warn you of any impending objects. Another obvious sign is an indicator that refuses to change status - this can range from an intermittent beep (even when the car is moving forward) to a constant beep in reverse (even if there are no obstructions in its path). In some cases, the entire system may not work at all (which is how some vehicle's systems respond to one bad sensor). If you have any suspicion of a faulty sensor, the best way to pinpoint it is to use a scanner that's compatible with your make. You can also check for any ice or debris covering the sensor, or you can trace and check the electrical connectors for damage.

Can I replace the parking sensors myself?

Many parking sensors can be replaced by the novice do-it-yourselfer, but the degree of difficulty will vary depending on the model. Some models will require the removal of the rear bumper cover, other processes will be as simple as removing the sensor and punching a new one in. There are also various types of parking sensor systems, so the type of system can also elongate or shorten the process. The simplest and easiest process will entail the removal of the sensor's fittings followed by the sensor itself. Some sensors can be disconnected directly from the wiring; others are wired all the way into the vehicle, which means they'll have to be disconnected from a different point and might require the removal of other parts like the wheel well panel or lower dash trim panel. 

Need to Replace your Vehicle's Parking Sensors?

Parking sensors are commonly damaged, ironically enough, from people hitting things - the exact thing that they are used to prevent. So, if you need to replace a faulty assist sensor or sensors due to a parallel parking fiasco or from backing up into a parked car in a narrow parking garage, 1A Auto is here to help. At 1A Auto, shopping for a replacement back-up sensor for your vehicle is easy, just call our customer service toll free at 888-844-3393, or you can buy online right here at 1AAuto.com.
