Your Tesla parking sensors may stop working due to certain reasons, so you need to know the procedure on how to fix them.

To fix your Tesla parking sensor, you must first figure out why the sensor stopped working. For example, your Tesla’s sensor may stop working due to a worn-out system, damaged wiring, or obstruction from dirt. Next, try cleaning the sensors, changing the wiring system, or replacing the sensors.

In this article, I’ll explain why your Tesla parking sensors may stop working and how to fix them. You’ll also get to know how to reset your parking sensors when necessary.

How Do I Fix a Tesla Parking Sensor?

The procedures to fix your Tesla parking sensor are simple as long as you know why it needs fixing. 

Before you attempt to work on your Tesla, you must first determine the reason for its malfunction. 

Here is a list of some common reasons why your parking sensors may become faulty:

• Built-up dirt on the sensors. 
• Damaged wiring in the sensors
• Worn out sensors

#1. Build Up of Dirt on the Sensors

The parking sensors on your Tesla can get dirty. When you don’t properly clean the sensors from time to time, the dirt can build up and compromise their operating performance.

You’ll need some materials to clean off the dirt on your parking sensors properly. 

Below is a table showing the materials you’ll need and their respective uses:

Materials	Uses
WD-40 spray	To remove tough dirt and debris
Microfibers	To rinse off the dirt on the sensors
Container and car shampoo	To prepare a water solution for cleaning the sensors

Here are steps on how to clean your Tesla’s parking sensor properly:

• The first step is to mix up a water solution for your parking sensor. Pour some car shampoo and warm water into a container and let it rest for a few seconds.
• The next step is submerging the microfiber into the solution and carefully rinsing off the dirt from the sensors. 
• If the dirt doesn’t come off easily, spray the WD-40 on the sensor’s surface and wait for a few minutes.
• Get a cotton swab and submerge it into isopropyl alcohol. Then, insert the cotton swab into the sensors and gently clean off all the dirt.
• Clean off the alcohol around the sensors with a damp microfiber.

#2. Damaged Wiring in the Sensors

If the parking sensors still don’t work even after the cleaning process, then the problem is probably from the wiring.

The parking sensors’ wiring system helps them send and receive signals. If the wiring is damaged, your parking sensors will stop working.

Here are steps on how to test if the wiring of your parking sensors is damaged or not:

• First, disconnect the negative terminal of the sensor’s battery.
• After you disconnect the battery’s negative terminal, test the continuity of the wires with a multimeter. You can find the wire harness near the front or rear bumper.
• If you discover no continuity, then there is a problem with the wiring. You’ll need a professional to get the system back into shape.
• If the multimeter detects continuity, connect the negative terminal back to the battery and test the sensor. If the sensor still doesn’t work, then it needs replacement.

#3. Worn-Out Sensors

The parking sensors on your Tesla get worn out over time and may stop working due to this. If your parking sensors wear out, you need to replace them.

#4. How to Replace Your Tesla’s Parking Sensors?

Here is a table showing the materials you’ll need to replace the sensors on your Tesla and their uses:

Materials/Tools	Uses
Power drill	To drill out holes in the sensor unit
Tapping screws	To secure the sensors
Screwdriver	Insert the screws into the holes

Here are steps on how to replace your Tesla’s parking sensor:

• The first step is disconnecting the parking sensor’s unit from the wire harness and ground wires. Next, you can find the sensor unit on the side or rear bumper.
• Drill out holes in the sensor unit with your power drill. Ensure to use bits that are smaller than the sensors.
• Insert the new sensors into the holes and secure them with the tapping screws. Once the sensors are properly in place, you can reconnect the ground wire and wire harness.

How Do You Reset Parking Sensors on Your Tesla?

It is necessary to be aware of how to reset your parking sensors. For example, your Tesla’s parking sensors may temporarily stop working when the park assist gets blocked.

Here are some reasons why your Tesla may block your park assist:

• The park assist may get blocked when you drive your Tesla through severe weather conditions such as snow, fog, and heavy rainfall
• The park assist may get blocked when you drive at high speed when moving out of your parking space.
• Your Tesla’s park assist may get blocked when the sensors get obstructed by dirt and debris while offroading.
• Your Tesla’s park assist may get blocked when you damage the parking sensors. 
• Trailer hitches or tow trailers may cause your park assist in getting blocked.

Here are steps on how to reset the parking sensors on your Tesla vehicle:

• The first step is to turn on your Tesla
• For about ten seconds, click on the park assist button on your vehicle repeatedly
• After ten seconds, switch off the ignition on your car
