  • carssimplified... • In this video, we take a look inside a Schrader universal fit tire pressure monitor sensor (TPMS) to show you what's inside and how it works. This example failed and was replaced by someone else.

    In the future we will make a video about how to replace a TPMS sensor.

    Interesting! Thank you!

    Can you make a video explaining the clutch? As in how a manual transmission car works.
    Or can you please make a video talking about how to choose a first car?

      I'll see if I can get my hands on a demonstration clutch; I definitely want to make a video about that. Choosing a first car is a video I can definitely get done sooner, so I'll add that one to my list! Thanks for the requests!

    What's the little hole in the case to get at the battery for?

  • @kellicees5568
    @kellicees5568 6 лет назад +2

    I knew there were tire pressure sensors, but it never occurred to me that they would have to be powered by something. I guess a small battery is the best way to do that! Do they shut off when you turn the car off?

    • @CarsSimplified
      @CarsSimplified  6 лет назад +1

      Some advanced ones may go into low power mode, but if they turned completely off, they wouldn't be able to receive an on command, so they start slowly draining the battery as soon as they are manufactured.

    Open it with an exacto knife. The 2032 is not the complete number. You need the 2032 that can withstand up to 40 below and has the solder tabs on it. Then you can replace the battery and reseal it with a thin bead of silicone. then it will be good for several years again.

    What frequency sensors work? How to test the signal?

    • @CarsSimplified
      @CarsSimplified  3 года назад

      I don't recall the frequency and a quick search didn't come up with the results I wanted, but testing the signal can be done with an oscilloscope.

      @@CarsSimplified Very few people have an oscilloscope that has a 500 MHz or even 1 GHz bandwidth. So no, that's absolutely not feasible :D

    What camera did you use?

    • @CarsSimplified
      @CarsSimplified  6 лет назад +1

      For this and most of my videos lately, I have been using a Canon EOS Rebel T5i ( amzn.to/2AH5zyX - No longer in production?) with the 18 to 55mm lens (that it came with) zoomed most of the way in. I am sure there are better cameras out there for the job, but it really just takes a tripod, a good optical zoom/focus at that zoom level, and a lot of light to film shots like this and most of my spark plug design video.
      I actually filmed a video two weeks ago talking about some of my gear, which I will try to get edited soon!

      That video is out now, I think.

    a battery might be dead and still read a decent voltage, you would need to put a load on it to measure voltage under a load. If you have a battery tester it would do it otherwise you would put a resistor across the battery to put it under a load. Also, your multimeter has a battery test function which will put a load, you could have tried that on the 9V range

    Yes, "it's supposed to be 3 volts". Wow.

    Another TPMS video that does NOT explain how the sensor functions and is triggered

      let me know if you find one or some text. I'm justnow searching.
