How does a TPMS work to let you know your tire pressure is low?
How does a TPMS work to let you know your tire pressure is low?
Direct TPMS uses a sensor mounted in the wheel to measure air pressure in each tire. If a tire’s pressure is low, it will roll at a different wheel speed than the other tires. This information is detected by your car’s computer system, which triggers the dashboard indicator light.
Why is my tire pressure low in one tire?
Low pressure could result from a leak or simply from the tendency of a tire to lose about a pound of air pressure every month, as well as a pound for every 10-degree drop in temperature. Once the tires are properly inflated, the light may go off after you’ve driven a few miles.
Can a tire pressure sensor be used without a TPMS?
I have the TPMS and even with the OBDII adapter, I cannot see tire pressure, only with the DIC. Without the DIC, all you would see on the dash is the TPMS light come on warning you that one or more tires have 25% lower air pressure than what is recommended.
Is it normal to have a low tire pressure reading?
This is normal if you understand how they work. This is normal if you understand tire pressure is dynamic. So did a little reading on TPMS vs external gauge pressure readings and consensus seems to be do not use the TPMS for setting tire pressures, rather use a handheld gauge for that and just use the TPMS for flat monitoring.
When did tire pressure monitoring system come out?
If your vehicle is not equipped with the system and TPMS sensors in the tires, you will not be able to monitor tire pressure via the DIC. I believe the TPMS system was introduced in 2006 on our platforms.
Why does my TPMS light never go out?
Drove the car for a week after verifying air pressure was good on all 4 tires before taking to Discount Tire to get the sensors read because the TPMS light never went out. See my response to Ddaddy for more about that.

What can I do about persistent TPMS warnings?
Persistent TPMS warnings can often be cured by setting the tire pressures properly and then resetting the TPMS somewhere in the menu on the driver’s display, or perhaps with a scan tool.
