Tesla Parking Sensors Not Working (This Worked For Me)

The Tesla uses sensors and cameras to operate almost all of its functions for the safety and comfort of the vehicle and passenger. One of the best features that Tesla provides is the parking sensors that help you in parking and driving through tight spaces.

When these features cause problems like parking sensors not working, it becomes very difficult and annoying to park and move your vehicle through tight spaces. The same happened to me and I even scratched my car.

So I did a lot of research to figure out what the causes are and how I can fix them.

So in this article, I’m going to tell you how you can fix the problem of Tesla parking sensors not working.

Let’s get started…

 How do parking sensors work?

Parking sensors are also known as proximity sensors or ultrasonic sensors. These are the devices that are made to help you in parking and moving your vehicle through tight places. These devices use ultrasonic technology to detect nearby objects and warm the driver through visual or audible warning signals.

These sensors are positioned on the exterior of your Tesla typically on the front and back bumper. When the driver activates the parking sensors, they emit ultrasonic waves in a cone-shaped pattern. These waves move forward until they strike an object. When the waves strike, they come back.

The parking sensors receive the reflected waves and calculate the distance between the vehicle and the object and send the signal to the main control unit and it warns the driver as the vehicle approaches near the object.

Tesla parking sensors not working – Causes And Fixes

The problem of Tesla parking sensors not working looks like a very big issue to resolve but it’s not like that. Its solutions are very easy. The causes for this problem in your Tesla could be one of these, Malfunctioning of Sensors, Malfunctioning cameras, and Software issues.

Now I am going to explain these causes and their solutions in detail. So keep reading.

01. Malfunctioning of Sensors

Sensors are the main component in your Tesla which performs many functions like parking. There could be many reasons for the malfunctioning of sensors like accumulation of dust and debris, loosen or damaged wiring, and damaged Sensors.

Solution

  1. If the sensors of the Tesla are malfunctioned then the first thing you should do is clean the sensors to remove the accumulation of dust and debris. Use a soft cloth or a microfiber cloth to clean the sensors properly.
  2. The second thing you should try is to remove the sensors and check for loose or damaged wiring. Also, check the wire harness that should be sitting in the Bonet.
  3. Remove the sensors and check the Voltage or current in the wires. If the voltage is low or there is no voltage at all. It means that you need to fix the wires or change them with new ones if needed.
  4. Also, check the wire harness that is sitting in the front Bonet. If you find any black spots on it, it means that the harness has been faulty and it needs to be replaced with new ones. If you have some technical work knowledge then you can easily replace and fix these.
  5. But when the sensor itself is faulty, you need to fix it or replace it with the new one as soon as possible. For this, you will need some professional assistance. Contact Tesla customer support service or visit the nearest dealership. The professional mechanics will diagnose your vehicle sensors and will fix them for you.
  6. Errors in the calibration of the sensors can also cause problems like that. So recalibrating the sensors can also fix the problem.

Follow these steps to recalibrate the parking sensors.

  • Ensure that your vehicle is parked in a safe and open area.
  • Make sure the vehicle is turned on.
  • Tap the “Controls” icon on the touchscreen.
  • Tap on “Parking” or “Parking Sensor.”
  • Tap on “Calibrate Sensors” or “Recalibrate.” to start the calibration.
  • Follow the on-screen instructions and complete each step as instructed.

Your sensors will be calibrated after following these steps.

02. Malfunctioning of cameras

Despite the sensors, Tesla also uses cameras while parking your vehicle. So malfunctioning cameras can also cause the problem of Tesla parking sensors. The reasons for the malfunctioning of the camera could be the accumulation of dust over the camera, loose or damaged wiring, faulty camera, or error in calibrations.

Solution

  1. The first thing you should do is clean the camera and ensure that there is no dust or debris over the camera.
  2. When the camera has been cleaned, the thing you should check and fix is the wiring. Check the wiring to if loosened from any end, and reconnect it tightly. If the wire is damaged, replace it with a new wire.
  3. If the camera itself has been damaged or has gotten faulty, you need to replace it with a new one. In this case, you need some professional assistance. Contact Tesla customer support service or visit the nearest dealership to inspect your cameras and fix them.
  4. Calibration errors in cameras can also cause this problem. Recalibrating the camera can also fix the problem.

To recalibrate the cameras follow these steps,

  • Ensure that your vehicle is parked in a safe and open area.
  • Make sure the vehicle is turned on.
  • Tap the “Controls” icon on the touchscreen.
  • Tap on “Camera” or “Camera Settings.”
  • Tap on “Calibrate Cameras” or “Enter Calibration Mode” to start the calibration.
  • Follow the on-screen instructions and complete each step as instructed.

Your camera will be calibrated after following these steps.

03. Software issues

The parking sensors may also stop working due to errors and glitches in the Tesla software. The errors and glitches can enter the Tesla due to outdated software, glitches in the software update, and connection of third-party apps or devices with the Tesla.

Solution

  1. The first thing you should do to resolve the problem is to remove or disconnect any third-party app or device connected to the Tesla.
  2. Now you should go and check if the software version is not outdated. If the update is available, update your Tesla software.

Follow these steps to update your Tesla software.

  • Show that your Tesla is connected to a stable Wi-Fi network.
  • Tap on the “controls” icon and scroll down and select “software“.
  • Tap on “software update” to check for available updates.
  • Tap on “Install now” or “Download and install“.
  • Follow the on-screen instructions to proceed with the installation.
  • After the update is installed your Tesla will automatically reboot.
  • Performing a soft reset can also fix the problem caused due to glitches and bugs in the software.

Follow these steps to perform a soft reset.

  • Ensure your Tesla is parked and brakes are engaged.
  • Hold down both of the scroll buttons on your steering wheel.
  • Wait for the touchscreen to turn black.
  • Wait for extra 30 seconds after the Tesla logo appears for the complete soft reboot.
  • If the soft reset doesn’t resolve the issue, you can go for a hard reset. You should go for the hard reset if you have tried all the other solutions for this issue.

You can also perform a hard reset by disconnecting the 12V battery and allowing the electronics to discharge.

04. Power supply issue

Parking sensors and all the other electrical devices require a stable power supply to perform well. Low voltage or insufficient power could cause this malfunctioning.

Solution

  1. Check the battery health of your Tesla. If not enough charge it or replace it with new ones if needed.
  2. Check the fuses associated with parking sensors, if any fuse has blown out, replace it with the new one. Read the owner manual to find out where the fuses are located and which fuse to check.

05. Electromagnetic interference

Electromagnetic interference can also disturb the functioning of parking sensors. This interference may arise from nearby devices or structures emitting strong electromagnetic signals.

Solution

Try parking your car away from these strong electromagnetic sources and relocate the devices away from the Tesla.

06. Connect customer support
