    You don’t.

    They’re a consumable item. When the batteries die you replace the entire set unless one sensor has clearly failed years before the rest.

    Manufacturers own (OEM) TPMS sensors can still be expensive, but not as bad as they once were. Off-brand alternatives sold by most tyre shops work pretty much as well but tend not to last anywhere near as long as OEM models.

    Your sensors are now at least 7 years old and will be 8 this year. That’s right on the average for lifespan of OEM sensors.

    The TPMS sensors in the tires have batteries in them that go bad so all 4 sensors may need replacing. That's around $300to $400. I'd put a piece of black electrical tape over the yellow warning light and buy a tire gauge to check the tire pressures once a month before spending that on replacing the tire sensors. A good tire gauge is Ten bucks.
