Get Professional Help For Troubleshooting Issues With Your Tesla Vehicle
Tesla cars are known for their advanced technology and modern design. But when it comes to troubleshooting, even the most tech-savvy owners can find themselves in a bind. A recent conversation on Tesla Motors Club highlighted an issue with a missing sensor or something located in the back of the central radiator box on a P90D 2016 (Facelift) Model S.
The user attached a picture of the location and the sensor wiring but was unable to locate what was missing from epc.tesla.com. Other users suggested that there might not be anything missing at all, as some models have unused connectors under the frunk tub closest to the front of the car. Another unused 2-pin connector is hidden behind the rear HVAC vent in the back of the center console, which could have been meant for a switch with an LED light to turn on/off the rear HVAC.
It was also suggested that this may have been used during testing and Tesla simply didn't redesign the wiring harness after that. The user then noticed where it looked like something was screwed in with two screws and asked for help finding it in the catalog. It was suggested to look carefully at the end of the connector and see if it is cleaner than the rest or if it looks the same, as it may never have been used. Lastly, it was recommended to check with your local Tesla Service Center for further assistance.
Troubleshooting issues with your Tesla vehicle can be difficult without professional help. If you're having trouble locating a missing sensor or other component, make sure to consult your local Tesla Service Center for assistance. They will be able to provide more information about what components should be present in your model and how to properly identify them. Additionally, they'll be able to provide advice on any necessary repairs or replacements needed for your vehicle's optimal performance.
What is the missing sensor located in the back of the central radiator box?
It might not be anything missing. It could have been used during testing and Tesla didn't redesign the wiring harness after that. It may never have been used. Check with your local Tesla Service Center for more information.
What year Model S do I have?
What are the wire counts and colors?
Looks like it's 3 wires colored black, orange, and red.
Where can I find wiring diagrams for my car?
You can find wiring diagrams for your car from the Tesla Service website. Just enter your VIN number and you'll be able to access the diagrams.
How do I check if the sensor is working?
You can use a multimeter to measure the resistance of the wires connected to the sensor. If it reads 0 ohms, then the sensor is working properly. If it reads infinite, then there may be an issue with the sensor.
What type of sensor is it?
It looks like it's a temperature sensor. It's used to measure the temperature of the air in the central radiator box.
What are some possible causes for the sensor not working?
Possible causes could include a faulty connection, a broken wire, or a damaged sensor. It's also possible that the wiring harness was never designed to include this particular sensor.
Is there any way to fix the problem without replacing the entire wiring harness?
Yes, depending on what is causing the issue. If it's just a faulty connection, you can try re-soldering or using electrical tape to secure it. If it's a broken wire, you can replace it with a new one. If it's a damaged sensor, you can replace it with a new one as well.
Is there any way to test the sensor without taking apart the wiring harness?
Yes, you can use a multimeter to measure the resistance of the wires connected to the sensor. This will tell you if it is working properly or not.
