Kia Optima Hybrid: Tire Pressure Monitoring System / TPMS Sensor Repair procedures

Removal
Tire Removal
1.
Deflate tire & remove balance weights.
   
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.

Sensor Removal
   
Handle the sensor with care.
1.
Remove the valve nut.

   
The valve nut should not be re-used.
2.
Discard the valve assembly.
Installation
Sensor Fit
   
Handle the sensor with care.
Avoid lubricant contact if possible.
1.
Assemble valve to sensor and turn valve 3 times with the square part of the screw in the slot.

   
The fit should not be tight i.e. it should still be possible to easily adjust valve angle.
Ensure that the wheel to be fitted is designed for sensor mount. There should normally be a mark to indicate this.
Ensure that the valve hole and mating face of the wheel are clean.
2.
Mount assembly to wheel.
   
Ensure sensor feet are against the wheel throughout the remainder of the assembly process.
3.
Tighten washer and nut by hand until the valve thread meets the nut built-in calibrated stop.
   
Ensure that the grommet remains in contact with the wheel.

4.
Using a torque wrench, tighten the nut to 2.95±0.37 lb-ft (0±0.5 Nm) It is normal to feel a break as the 1.7 lb-ft (2.3Nm) calibrated stop in the nut snaps and the torque falls.

   
Increase torque smoothly in order to achieve a clean break of the stop.
Do not exceed allowed torque.
Do not use electric or pneumatic tools.
Tire Fit
   
Only use wheels designed to accommodate the TPMS sensor.
1.
Lubricate the tire bead not the rim. Excessive lubrication should not be applied.
2.
Start tire mounting approx. 5.9 in(15 cm) from valve.
3.
Move the mounting tool away from the valve.
   
Avoid tire / tool contact with the valve.
4.
Finish with mounting tool near to valve.
5.
Carry out inflation / pressure correction and then fit valve cap.
