How do I know which TPMS sensor I have?
To know which TPMS (Tire Pressure Monitoring System) sensor you have, you'll need to check your vehicle's make, model, and year, as well as the sensor's location and specifications. This information can help you determine the right replacement sensor for your car.
Identifying Your TPMS Sensor
Here are the steps to identify your TPMS sensor:
- Check your vehicle information: Locate your vehicle's make, model, and year. This will help you determine the specific TPMS sensor required for your car.
- Locate the TPMS sensor: The TPMS sensor is typically located inside the tire, either on the wheel rim or the tire valve stem. You may need to remove the tire to access the sensor.
- Inspect the sensor: Look for the sensor's part number, manufacturer, and any other identifying information. This will help you find the correct replacement sensor.
- Consult your owner's manual: Your vehicle's owner's manual may provide specific details about the TPMS sensor, including the part number and replacement instructions.
By following these steps, you can accurately identify the TPMS sensor in your vehicle and ensure you purchase the correct replacement part.
Understanding TPMS Sensors
TPMS sensors are designed to monitor the air pressure in each of your vehicle's tires and alert you when the pressure drops below a certain level. These sensors are an important safety feature, as underinflated tires can affect your vehicle's handling, fuel efficiency, and tire wear.
TPMS sensors come in different types, including direct and indirect systems. Direct TPMS sensors are mounted on the wheel rim or tire valve stem and measure the air pressure directly. Indirect TPMS systems use the vehicle's anti-lock braking system (ABS) sensors to estimate tire pressure based on wheel speed.
Knowing the type of TPMS sensor in your vehicle can help you choose the right replacement part and ensure your system continues to function properly.
Why is my tire pressure light still on after filling tires?
If your light stays on after you fill your tires, the system is probably having trouble detecting the correct levels. However, if you're facing a flashing tire pressure light, you might be dealing with a broken sensor, or with a dying battery.
Does my car have direct or indirect TPMS?
Direct TPMS sensors are located within the tyre, usually in the space between the tyre and the wheel trim. As indirect TPMSs use the sensor on the anti-lock braking system (ABS), this sensor is typically located near the brake rotor.
Can you replace TPMS without removing a tire?
Many newer vehicles have a tpms system attached to the valve stem. It is not possible to remove and replace a tpms valve stem without removing the tire.
How to figure out which tire pressure sensor is bad?
Measure the air pressure of each tire and record them. Then, compare the data with the one displayed in your car display panel. If the reading in one tire is different from the one displayed, it might mean that there's a problem with the TPMS sensor in that tire.
How do I know which TPMS sensor to buy?
First, compatibility with your vehicle's make and model is essential to ensure a proper fit. Accuracy and reliability of pressure readings, ease of installation, durability, and battery life are also crucial considerations. Additionally, consider whether the sensor is programmable or requires specific tools for setup.
Do I need to reset TPMS after tire change?
If you have an indirect TPMS system, your mechanic will need to manually reset the sensors after changing your tires. If you have a direct TPMS system, no additional maintenance is required to reset the system. A new TPMS system will typically last for about 10 years before the batteries run out.
Should I replace all TPMS or just one?
If one of your TPMS sensors fails and needs replacement, you can replace it individually. However, if the failure was caused by a dead sensor battery, it's likely that the other sensors are close to failing as well.

Can AutoZone check TPMS sensors?
You can get them replaced at most tire shops like Walmart, Discount Tire, Firestone, and PepBoys. Plus, Walmart and AutoZone test your sensors for free so you can figure out if they're bad or not.
Can I replace just one TPMS sensor?
If one of your TPMS sensors fails and needs replacement, you can replace it individually. However, if the failure was caused by a dead sensor battery, it's likely that the other sensors are close to failing as well.
