4+ Hacks On How Can You Tell If a Parking Sensor Is Bad
“You know you’ve got a bad parking sensor when your car is always getting towed. The low battery light and the beeping alarm sound the same as any other. The question now is how do you know if it’s just one of those days or if there is something wrong?”
Well, we’re here to help. Here are some signs that indicate that your parking sensor might be on its last leg:
1. Hire a Professional
You know, those little things that tell you when someone is backing out of a parking spot, so you don’t rear-end them? Yeah, those are cool. They help make sure nobody gets hurt on the road. But what if one day they just stop working?
- Go to dealerships around you, but make sure they are really professional at what they do as this can cause you more damages; wait for 2-3 hours until you get attended to and pay 200 dollars or more for diagnostic, depending on environment and car model.
2. Self Diagnostic
If you are a technical person, you might want to take this approach. All you need to do is visit any stores(both online and physical) to get mini-VCI cable for about $50 or more, this depends on the features and brand.
And you can as well purchase any of the best OBD2 scanners of your choice from eBay, Amazon or any other store. The next thing to do is install compatible software spending around 3-4 hours to figure out how the device and software works.
The next thing to do is plug the machine into the OBD2 plug on the car to check the status of your parking sensors; the bad parking sensors will either be stuck or show no reading at all.
3. Use Your Smartphone
Some of the parking sensors out there emanate sounds and clicks that are too weak for the ears to detect. In this case, you can make use of your smartphone voice microphone and sound system for diagnosis.
It is worth noting that this approach can be quite complicated, but it works better if you use an app that allows you to build a chart of incoming sound. So the operating system of your phone and the application are irrelevant in this case.
To first step to using smartphones for parking sensor diagnosis is activating the app and bringing the microphone close to the parking sensor. Do this for up to 5 minutes. – If the sound recording are signals, they will be visible on the chart and there will be audible clicks coming out from the recordings. Note: This is better done in a silent environment.
4. Use Tactile Check
Assuming you are in a situation where you can’t hire a professional or make use of a smartphone to diagnose your parking sensors, the tactile check might be the best for you. However, it is better done when you have a partner.
To check your reverse parking sensors, you should put the gear lift in reverse. And to check your car front sensors, set “Drive” mode on automatic transmission or set first gear if your car uses manual transmission.
If the sensor is operational, it emits 5-10 clicks per second when an object is at close range. So if you put your finger on it, the sensor surface should vibrate. But for you to have a better feeling of the sensors signal, you should move your finger a little over it.
You need to do this for each of the parking sensors to know which one is working and the one that needs to be changed. While you are at that, your partner should be monitoring the dashboard to see how the system reacts to every touch.
5. Use a Multimeter
Using Multimeter is another reliable method of how you can tell if a parking sensor is bad, but it has a downside at the parking sensors needs to be removed from the car. And to get the best out of it, the tester must be set to electrical resistance measurement mode.
Another thing you should know about this method is that the electrical resistance value for each sensor may differ, however, it is important to watch out for short circuits or no break. For parking sensors with three-contact, the first contact is the plus, the second contact is the signal and the third contact is minus.
For a working sensor, the resistance between the plus and minus should be more than 0.5 megohms. The resistance between the minus-signal contact should be in the order of 2 – 40 kOhm depending on the sensor. – And there should be something similar between the signal contact and plus.
Frequently Asked Questions and Answers
In this section are answers to common questions on how can you tell if a parking sensor is bad and other related topics.
Are Parking Sensors Fragile?
It depends. Parking sensors are typically made of plastic, which is not as sturdy as metal. If you have a particularly bumpy driveway or live in an area with lots of loose gravel, the sensor might break more easily than other types of plastic.
You can avoid this problem by keeping your car on smooth surfaces and avoiding potholes whenever possible.
How Much Does it Cost to Replace a Parking Sensor?
It turns out that the average cost for a new parking sensor is about $50-$60. If your vehicle has one or more broken sensors, then there are some steps you can take to try and diagnose the issue yourself before calling in an auto mechanic.
Can You Reset Parking Sensors?
To start off, check the instructions manual for your specific make and model of vehicle. If your manual doesn’t cover it or is unclear on the topic, try looking online for information. You can also ask a mechanic or call up your local dealership – they should be able to answer any questions about the process of resetting parking sensors. But you can’t reset parking sensors using any tools or hacks.
Can You Fix Parking Sensors with WD40?
There are plenty of internet forums and blog posts out there attempting to answer this question, but the answer is more complicated than it may seem.
Parking sensors can be used in both residential and commercial settings. If your sensor isn’t working properly, or if it’s not detecting objects like curbs and poles, then you’ll need to find a way to fix these issues before they become too big of an inconvenience for drivers using your parking lot.
A few ways that have been tried include spraying the sensor with WD-40, lubricating them with graphite powder, tapping on them lightly with a hammer or even just blowing on them gently from time.
So, you’re in need of a parking sensor and don’t know where to turn. We’ve put together this simple guide on how you can get the job done without hiring a professional.
But, while reading our tips for troubleshooting some common problems with sensors, remember these are only meant as quick fixes — you should always have professionals handle installing your device if it is important that they work correctly from day one.
