TIRE PRESSURE LIGHT RESET

2009 Kia Spectra • 4 cylinder FWD Automatic • 20,000 miles

My granddaughter has a KIA 2009 Spectra she has new tires and the valve stems do not leak. The TPMS light will not go out. I know one of the monitor devices my be bad but. My question is. How do I rest the TPMS on the onboard computer so the TPMS light will go out?

RESET PROCEDURES
NOTE: If tire pressure sensor is replaced, it will need to be initiated. See TIRE PRESSURE SENSOR INITIATION.

TIRE PRESSURE MONITOR WARNING INDICATORS
When the low tire pressure warning light comes on, check the air pressure of all tires and adjust to the specified cold pressure listed on vehicle certification label (found on driver's door or door pillar). If tire is damaged, repair as necessary. Ensure the warning light goes off (this may take up to 4 minutes if the tire is not rapidly re-inflated).
If the warning light stays on, recheck tire pressure. If tire pressure is okay, turn wheel a quarter turn and wait another 4 minutes (the sensor may be in an RF null). If the warning light is still on or if the TPMS warning indicator is lit, there is a malfunction in the TPM system. See appropriate manufacturer service information.
TIRE PRESSURE SENSOR INITIATION
NOTE: In the following procedure, a TPMS exciter scan tool must be used.

NOTE: If tire pressure sensor is replaced, it will need to be initiated.

NOTE: Do not perform this procedure if vehicle is parked on a metal floor, roof, or on an alignment rack or lift. The metal will transfer the RF signals, which can cause the learn procedure to fail and set Diagnostic Trouble Codes (DTCs).

Change the state of the TPMS sensor, using the TPMS exciter, to "Normal Fixed Base mode".
NOTE: TPMS sensor arrive to the dealership in the storage auto mode.

Read each tire pressure sensor ID in the following order: front left, front right, rear left, then rear right.
Connect TPMS exciter to Data Link Connector (DLC) located under left side of instrument panel. Register the 4 sensor IDs to receiver. See Fig. 2 and Fig. 3.
Disconnect TPMS exciter from diagnostic link. Cycle ignition and wait 15 minutes.
Check to see that the TPMS system recognize each tire.
Use the TPMS exciter to verify all 4 tire IDs have been registered.

This did not help! Thanks anyways. Your standard book answer did not tell me how to reset the system for the light to go out. Thanks for the effort.

Could be a problem with a tire pressure sensor and underinflated tire.

The TPMS sensors, located in each wheel well, measure the tire pressure and temperature and transmit the data to the TPMS receiver. The tire pressure sensor operates in 4 modes: configuration mode, normal fixed base mode, storage auto mode, and alert mode. In configuration mode, the sensor will measure pressure and temperature every 20 seconds, and transmit every 3 minutes 20 seconds. In normal fixed base mode, the sensor will transmits and measures as in the configuration mode until the TPMS sensor receive a command to switch into another mode. In storage mode, the sensor enters a low current consumption state where no measurements are made in order to conserve battery power. The sensor will not transmit unless requested to do so by the initiate command. In alert mode, the sensor will measure and transmit every 4 seconds. The TPMS sensor will enter this mode when the temperature is more than 230 degrees and the tire pressure change 3 psi from the last transmission
