Tire pressure sensor
Each sensor is an integrated unit made up of the tire valve stem, a pressure sensor, and a transmitter. The unit is
attached to the inside of the wheel, around the valve stem. The sensor transmits the internal tire information to the
control unit once every 60 seconds when the vehicle speed exceeds 28 mph (45 km/h). When the TPMS control unit
receives a tire pressure signal that is less than 168 kPa (1.7 kgf/cm , 24 psi) with 16 inch wheels, or 175 kPa (1.8 kgf/cm ,
25 psi) with 17 inch wheels, the TPMS control unit then turns on the low tire pressure indicator. When that tire's
pressure is increased to more than 190 kPa (1.9 kgf/cm , 28 psi) with 16 inch wheels, or 200 kPa (2.0 kgf/cm , 29 psi)
with 17 inch wheels, and the vehicle is driven above 28 mph (45 km/h) the transmitter sends the tire pressure signal to
the control unit, and then the control unit turns the indicator off.
NOTE: Do mix the TPMS tire pressure sensors or wheels with other TPMS types. Be sure to use the correct type
sensors and wheels for this system.
Sensor are active:
• When the wheel rotates over 28 mph (45 km/h) the sensor detects the momentum, and switches the sensor to the
normal function mode.
• The LF (low frequency) signal of the TPMS initializer tool makes the sensor active even though the vehicle is stopped.
The tire pressure sensor goes into sleep mode when the acceleration sensor detects the wheel is stationary for
5 minutes or more.
Wheels
TPMS will not work unless TPMS type wheels are installed on the vehicle. There are six different type of wheels used.
The original equipment wheels have a ''TPMS'', ''TA0'', or ''TE0'' mark (A) on them and counterweights (B) are
mounted to counter balance the weight of the tire pressure sensor (C).
