Kia Sportage: Tire Pressure Monitoring System / Description and operation
TREAD Lamp
| – |
Tire Under Inflation / Leak Warning.
|
| 1. |
Turn on condition
| • |
When tire pressure is below allowed threshold
|
| • |
When rapid leak is detected by the sensor.
|
| • |
Indicates that tire needs to be re-inflated to specified pressure
/ repaired.
|
|
| 2. |
Turn off condition
| • |
Under-inflation : When tire pressure is above [warning threshold
+ hysteresis].
|
| • |
Rapid Leak : When tire pressure is above [leak warning threshold].
|
|
DTC Warning
| 1. |
Turn on condition
| • |
When the system detects a fault outside the receiver/ sensor.
|
| • |
When the system detects a receiver fault.
|
| • |
When the system detects a sensor fault.
|
|
| 2. |
Turn off condition
| • |
If the fault is considered 'critical', then the lamp stays on
throughout the current ignition cycle (even if the DTC has been
demoted). This is because it is important to bring the problem
to the driver's attention. On the following ignition cycle,
the demotion conditions will be re-checked. If the demotion
conditions occur, the lamp will be turned off. It will stay
on until DTC demotion checking is completed.
|
| • |
'Non-critical' faults are those that can occur temporarily e.g.
vehicle battery under voltage. The lamp is therefore turned
off when the DTC demotion condition occurs.
|
|
| • |
When driving in high altitude grades, it is natural for the
atmospheric pressure to decrease. Therfore, please check the
tire pressure and add more air as necessary. Additionally required
tire air pressure per km above sea level : 1.5 psi/km
|
| • |
Tire pressure can be decreased naturally due to decrease in
ambient temperature (especially in winter). In this case, fill
tires with air to the specification if warning lamp is illuminated
as this is natural phenomenon.

|
System Fault
| 1. |
General Function
| • |
The system monitors a number of inputs across time in order
to determine that a fault exists.
|
| • |
Faults are prioritized according to which has the most likely
cause.
|
| • |
Up to 15 faults can be saved.
|
| • |
Certain faults are not covered through DTC. These include:
|
| a. |
Sensor thermal shutdown (over 257°F/125°C).
|
| b. |
Stuck Ignition Line: requires observation of lamps at
Ignition ON to diagnose.

The sensor is to maintain a certain distance from the vehicle in front. However,
the smudged sensor or sensor cover with foreign substances, such as snow and rain,
adversely affects the sensing performance.
It may even temporarily cancel the AEB. Always keep the sensor clean. ...
Removal
1.
Disconnect the battery negative terminal.
2.
Remove the intake manifold stay(A).
