Why does my low tire light come on sometimes and then go off by it’s self?
TPMS sensors have an internal battery. If the battery power is low, it can cause TPMS problems. When you have your tires changed, have them check your TPMS sensors and replace as needed. If you are worried about future problems it would be a good time to replace all of the sensors. When the battery level is low they can act up intermittently.
Ambient temperature changes will cause tire pressures to change. Tire pressures will drop about 1 psi for every 10°F drop in ambient temperature. This can cause your TPMS warning light to come on in cold temperatures, then go out as the tire warms up while driving.
Can I use TPMS sensors from one vehicle on a different vehicle?
If the TPMS sensors are not the right ones for your vehicle, then they probably wont work as the run on different frequency’s. The TPMS tool also wont read the sensors unless the proper vehicle is selected in the tool menu. If they are aftermarket sensors, the may be set up to a new vehicle with a TPMS tool if applicable.
What if I have an extra set of tires and wheels (snow tires)?
You can purchase a set of replacement sensors and have them installed in your extra set of wheel assemblies. When the extra set of wheel assemblies are mounted to the vehicle, the TPMS sensors may have to be relearned to the vehicle’s computer. Also, when the original set of wheel assemblies are reinstalled on the vehicle, the original sensors will need to be relearned to the vehicle’s computer. Some aftermarket sensors can be cloned to the original sensors eliminating the need to relearn the sensors each time the wheel assembly’s are changed.
What is a tire placard and where can I find it?
The vehicle placard is normally located on the drivers inside door jam or door. It contains information including the vehicle manufacturer’s recommended tire pressure, tire size and the maximum load you should have in your vehicle. The recommended tire pressure may also be found in the vehicle owner’s manual.
What pressure should my tires be inflated to?
Tires should be inflated to the vehicle manufacturer’s recommendation as found on the vehicle tire information door placard. Do not fill the tire to the pressure listed on the sidewall, this is the maximum allowable tire pressure for the tire.
Why does tire pressure change?
Many things can affect tire pressure. Ambient temperature changes will cause tire pressures to change. Tire pressures will drop about 1 psi for every 10°F drop in ambient temperature. Tire problems and damage such as punctures, and corroded or cracked rims can also cause tires to loose pressure. Tires can lose as much as 1.5 psi per month normally, as air escapes the tire and rim naturally.
What does it mean when my TPMS light comes on?
The TPMS light can come on in two different ways with two different meanings:
TPMS warning light comes ON and stays ON
One or more of your tires may have a low-pressure condition. Inspect all of your tires and check the air pressure. The correct air pressure for your vehicle can be found on the placard, usually located on the inside door panel.
TPMS warning light comes ON and flashes ON for one second and OFF for three seconds
This indicates a malfunction with the vehicle’s TPMS system.
Can the TPMS system be bypassed or disabled?
No it is against the law to disable a TPMS system. Under 49 U.S.C. 30122(b), “A manufacturer, distributor, dealer or motor vehicle repair business may not knowingly make inoperative any part of a device or element of design installed on or in a motor vehicle or motor vehicle equipment in compliance with an applicable motor vehicle safety standard.”

What if I change my oil before the light comes on?
Your oil life monitor will need to be reset every time you change your oil even if the light is not on yet. If it is not reset it will come on before the next oil change is due. This is a common problem because if the light is not on and the mechanic doesn’t know the vehicle has an oil life monitor it will not get reset.
