Kia Sportage: Tire Pressure Monitoring System / TPMS Sensor Repair procedures

Kia Sportage QL (2015-2024) Service Manual / Suspension System / Tire Pressure Monitoring System / TPMS Sensor Repair procedures

Removal

1.	Remove the valve core and deflate the tire.

Remove the side of the tire bead area from the wheel using tire changing machine .

•	The tire bead should be broken approx. 90° from the valve side of the wheel. The bead breaker should not be set too deep.

•	Avoid tire/tool contact with the valve on dismount.

•	Dismount should end near the valve.

3.	Rotate the wheel clockwise.

4.	Check for deviation of the valve (air inlet portion in silver) during transportation and assemble the valve in the indented state from the original position (metal brackets).

5.	To prevent the valve from rotating and deviating the set position while the nut is being tightened, push the valve into the set position (inside the metal brackets). Tigthen to the specified torque (8 Nm) and do not reuse the nut.

6.	Push the valve into the valve hole so that the seal washer touches the rim.

7.	While holding the housing with two fingers, push in the valve in the axial direction with another finger.

8.	The housing laser marking should be visible.

9.	When the valve is fully inserted, start tightening the nut several times by hand while keeping the sensor contacting the rim.

10.	Mount the nut using a tool while maintaining the position of the valve and the sensor.

11.	Apply tire soap or lubrication to the top and bottom tire beads.

12.	To fit the bottom bead, position the sensor at the 5 o’clock position relative to the head on the tire changing machine.

13.	Place the tire on the rim so the bottom bead touches the edge of the rim after the sensor (@6 o’clock). Rotate the rim clockwise, and push down on the tire at the 3 o’clock position to fit bottom bead.

14.	After bottom bead is on tire, rotate the rim until the sensor is at the 5 o’clock position relative to the head on the tire changing machine. Push down on the tire at the 3 o’clock position and rotate the rim clockwise to fit the top bead.

15.	Inflate the tire until both beads seat.

16.	In case of TPMS sensor failure, TPMS sensor learning is needed. After replacing faulty sensor with a new unit, perform TPMS sensor learning.

Inspection

Inspection after installing TPMS sensor

1.	Seal washer must be compressed on the outer surface of rim hole.

2.	The lower part of the valve must locate in the set position (within metal bracket) of the housing.

3.	One or more points of the housing must be contacting the surface of the rim.

4.	The mounting height of the housing must not exceed the sill of the rim.

Replacement

Repair tire after using the Tire Mobility Kit (TMK)

When the TPMS warning lamp OFF

1.	Remove the TMK repaired tire, wheel and TPMS sensor. (Refer to "Tire removal")

Remove the sealant on the wheel and TPMS sensor (A) completely.

•	Clean the sealant on the housing and sensing hole of TPMS sensor with clean cloth, gauze or air inhaler.

•	To prevent the sensor and circuit board damage, do not use the pointed instrument and give a lot of impact.

3.	Install the TPMS sensor to the new tire.

4.	Check for normal operation of TPMS system.

When the TPMS warning lamp ON

1.	Remove the TMK repaired tire, wheel and TPMS sensor. (Refer to "Tire removal")

Remove the sealant on the wheel and TPMS sensor (A) completely.

•	Clean the sealant on the housing and sensing hole of TPMS sensor with clean cloth, gauze or air inhaler.

•	To prevent the sensor and circuit board damage, do not use the pointed instrument and give a lot of impact.

3.	Install the TPMS sensor to the new tire.

4.	Check the tire pressure using the electrical tire pressure gauge.

5.	Check the tire pressure of TPMS sensor using the GDS.

6.	If the difference between two checked pressures in the above is not more than 2 psi, TPMS sensor is normal. Reinstall it to new tire.

7.	If the difference between two checked pressures in the above is more than 2 psi, TPMS sensor is abnormal. Install new TPMS sensor to new tire.

8.	Check for normal operation of TPMS system.

Diagnosis procedure by using diagnostic device

The main contents of diagnostic method using diagnostic device are as follows:

1.	Connect self-diagnosis connector (16 pins) located in the lower driver side crash pad to self-diagnosis device, and then turn on the self-diagnosis device after key is ON.

2.	Select the "vehicle model" and "TPMS" on GDS vehicle selection screen, then select OK.

[Register Sensor initialization]

[Register Sensor function description]

•	Check that Write ID and Read ID are the same.

•	After successfully registering the sensor, perform "Sensor Wireless Information" to confirm that the sensor operates properly.

[Sensor Status initialization]

•	Each entry must be checked for normal operation of each sensor.

•	After replacing the tires or sensors, check for proper operation of sensor after sensor registration process.
