SUBJECT VEHICLE: 2009 Kia Rio.
SENSOR IN TIRE? No (sensors are located in each wheel well).
RESET PROCEDURE? Yes (whenever a new sensor has been installed).
SPECIAL TOOLS NEEDED? Yes (TPMS exciter scan tool).
The tire pressure monitoring system (TPMS) for the 2009 Kia Rio consists of the following components: a TPMS receiver, four radio frequency tire pressure monitor sensors, a low tire pressure warning indicator and a TPMS warning indicator.
The TPMS sensors are located in each wheel well. They measure both tire pressure and temperature and transmit data to the TPMS receiver.
Sensors operate in four modes: configuration, normal fixed base, storage auto and alert.
In configuration mode, the sensor will measure pressure every 20 seconds and will transmit every three minutes and 20 seconds.
In normal fixed base mode, the sensor measures and transmits in the configuration mode until the TPMS sensor receives a command to switch into another mode.
In storage mode, the sensor enters into a low power consumption state where no measurements are made. The sensor will not transmit unless asked to.
In alert mode, the sensor will measure and transmit every four seconds. The sensor will enter this mode when the temperature is more than 230 degrees and the tire pressure changes 3 psi from the last transmission.
The TPMS receiver decides which warning indicator to illuminate from the radio frequency data sent to it by the sensors. When tire pressure falls beneath a certain threshold, the low pressure indicator on the instrument cluster will illuminate.
If the TPMS detects a fault with the receiver or sensor, the TPMS warning indicator also will be illuminated. If the fault is considered critical, the light will stay on throughout the whole ignition cycle.
