Since 2007, all passenger cars and light trucks sold in the U.S. are required to have factory-installed TPMS. Unlike many countries, TPMS isn’t mandated in Canada, but an estimated 70 per cent of vehicles sold since 2007 are equipped with TPMS.
HOW TPMS WORKS
TPMS uses a wheel-mounted sensor or the ABS system to detect tire pressure and then send a signal to the vehicle’s computer if low tire pressure is detected That’s when the TPMS warning symbol will light upon the dashboard.
There are also two types of TPMS warning symbols. The most common low tire pressure light looks like a treaded horseshoe with an exclamation mark inside. The other TPMS symbol is the frame of a vehicle which highlights the tire with the low pressure.
