- Most tire shops and repair shops recommend servicing the TPMS after changing or installing new tires or wheels by replacing the valve core, retaining nut, seal and cap on the valve stem, then testing the system to make sure it’s operating correctly.
Subsequently, How do you know which tire sensor is bad? 
What happens if you don’t replace TPMS sensors? For any motorists that swap their tires out for changing seasons, it’s crucial that the TPMS sensors are reactivated and recalibrated each time. If this is not done, the vehicle’s TPMS will not perform properly and may cause the TPMS light to turn on.
Yet, Can I drive with TPMS light on? It’s not safe to drive around with your TPMS light illuminated. Without a tire inspection, there’s no way of knowing how quickly air is leaving your tire, or for how long it has been over or underinflated. The best course of action is to use a tire pressure gauge to check the current inflation level of each tire.
How do you fix a TPMS sensor without replacing it? 
Can you drive with a bad tire sensor?
No, driving with the TPMS Light on is not safe. It means one of your tires is underinflated or overinflated. You can find the proper tire pressure for your car in your owner’s manual, or on a sticker located on the door, trunk, or fuel door.

Are tire sensors expensive?
TPMS Replacement Costs and What to Expect In the event TPMS sensors need to be replaced, the cost can range from approximately $50-$100 each depending on vehicle type.
Why TPMS light on but tires are fine?
If you notice the tire pressure light come on, it’s probable that one or more of your tires has low air pressure. You should not rely solely on the reading from the vehicle’s tire pressure monitoring system though; there are numerous factors that can cause the sensors to go off even if your tires are in good shape.
How long do tire pressure sensors last?
The lithium ion batteries inside TPMS sensors may last anywhere from five to 10 years. Five to six years is a more typical lifespan for older TPMS sensors. TPMS sensors don’t broadcast a continuous signal but only broadcast when the vehicle is in motion. Even then, the signal is intermittent to conserve battery life.
