FAQ About TPMS

How often should I check my tire pressure?
A tire doesn’t have to be damaged or punctured to lose air. All tires will lose air naturally over time, so it’s recommended that you check the pressure in all your tires, including the spare, at least once per month. Road conditions, weather conditions or other circumstances may warrant checking the pressure more often. Remember to always use a quality tire gauge when checking tire pressure. And don’t forget the spare! It may not have TPMS, but if you’re checking your tire pressure, you should check your spare tire, too.
What does an underinflated tire look like?
You cannot always tell if a tire is under-inflated simply by looking at it. You cannot easily tell if a tire is under-inflated by kicking or pressing on the tire. The only way to accurately check tire pressure is by using a quality pressure gauge. A tire can lose air pressure without appearing to be under-inflated. To see how little difference there is in appearance between a properly inflated and an underinflated tire.
Why does tire pressure change?
Many factors affect tire pressure including ambient temperature changes and tire damage such as punctures. Tire pressure drops about 1 psi for every 10°F drop in ambient temperature. Additionally, tires can lose as much as 1.5 psi per month as air escapes the tire and rim naturally.
Can the battery be replaced?
Generally, the battery of the internal sensor cannot be replaced, the battery of the external sensor cannot be replaced
How do I program the sensors?

My car has TPMS,but it doesn't work.What should I do?

• Verification that your TPMS sensors and system are functioning properly
• A “relearn” of your TPMS sensors to the monitor to program correct positioning of TPMS sensors
