Quick answer
You need a sensor that is set up for your car's year, make and model. That can be an OE-style sensor made for your car, or a programmable sensor that a tire shop or TPMS tool sets up for your car. Either way, the car has to relearn the new sensor before the light goes off.
OE-style vs programmable sensors
| Sensor type | Needs programming? | Needs a relearn? |
|---|---|---|
| OE-style, made for your car | No | Yes |
| Programmable (Schrader EZ-sensor, Autel MX-Sensor) | Yes, with a compatible tool | Yes |
| Autel MX-Sensor cloned from the old sensor | Yes (copies the old ID) | No, if it goes in the same wheel |
Schrader says its EZ-sensor ships blank and has to be programmed for your car with a compatible tool. Autel says its tools program only Autel MX-Sensors, though they can relearn other sensors that are already programmed. Autel also says a cloned MX-Sensor that copies the old sensor's ID and goes in the same position needs no relearn.
Three things to match
- Your car's protocol and frequency. Sensors talk on 315 MHz or 433 MHz, depending on the car. Don't guess from the brand. Look up your year, make and model. The Schrader EZ-sensor 33500 and Autel MX-Sensor cover both frequencies, and the programming tool sets the right one.
- The valve stem. Sensors come with a rubber snap-in stem or an aluminum clamp-in stem (metal, held by a nut). Match what's on your wheels now. Autel's MX-Sensor lets the stem be swapped between rubber and metal.
- A tool that works with the sensor. Schrader publishes a list of tools that can program the EZ-sensor. Autel tools program Autel sensors. A tire shop will have one.
Who installs it
The sensor is mounted inside the tire on the back of the valve stem, so the tire has to come off the wheel to replace it. For most people that's a tire shop job. Continental Tire puts a shop replacement at about $50 to $150 per sensor. Buying the sensor yourself and bringing it in can work, but call ahead, because some shops only install parts they sell.
Before you buy four sensors: make sure a sensor is actually the problem. A light that stays on solid usually means low pressure, not a bad sensor. See TPMS light on but tires look fine.

Questions people ask
Which TPMS sensor do I need?
One that is set up for your car's year, make and model. You can buy an OE-style sensor made for your car, or a programmable sensor like the Schrader EZ-sensor or Autel MX-Sensor that a shop or tool programs for your car. Either way, the car has to relearn the new sensor.
Are all TPMS sensors the same?
No. They differ by radio frequency (315 or 433 MHz), the protocol your car expects, and the valve stem (rubber snap-in or aluminum clamp-in). Programmable sensors cover many cars, but only after they are programmed for yours.
Do I need a 315 or 433 MHz sensor?
It depends on your car, so look it up by year, make and model instead of guessing. Programmable sensors like the Schrader EZ-sensor 33500 and Autel MX-Sensor cover both frequencies, and the programming tool picks the right one.
How much does it cost to replace a TPMS sensor?
Continental Tire puts a shop replacement at about $50 to $150 per sensor. The sensor sits inside the tire, so the tire has to come off the wheel to swap it.
