Kia Picanto: Exhaust Emission Control System / GPF (Gasoline Particulate Filter)
Description and operation
The
Gasoline Particulate Filter (GPF) system prevents Particulate Matter
(PM) from being discharged to the atmosphere and consists of a filter
assembly, two Exhaust Gas Temperature Sensors (EGTS).The filter is
integrated in the catalytic converter assembly and has honeycomb cell
structure which can filter the PM in the exhaust gas. While the exhaust
gas passes the GPF, This gathered PM in GPF is called "soot".

Repair procedures
This
procedures is to forcibly regenerate the GPF with scan tool when the
GPF doesn't have been regenerated during driving. For example, if the
vehicle has repeated "Low speed driving" or "Short distance driving",
the GPF regeneration procedure cannot be proceeded because "Regeneration
Mode" doesn't made.
•
| If performing the GPF service regeneration mode indoors, fire or burn injuries may occur by high temperature exhaust gas. Therefore the GPF service regeneration mode must be performed in a outdoor safe zone. |
|
Forcibly Regeneration Condition
–
| Engine coolant temperature : about 70°C |
–
| P-range (A/T) or Neutral (M/T) |
–
| Electrical fully load ON (A/C ON if equipped, Blower ON with maximum speed, Head Lamp ON, Wiper ON, Other Lamps ON, etc.). |
1. | Turn ignition switch OFF. |
2. | Connect a KDS to Data Link Connector (DLC). |
3. | Turn ignition switch ON. |
4. | Select "Vehicle, Model year, Engine, System". |
5. | Start engine at idle and P-range (A/T) or neutral (M/T). |
6. | Apply
electrical fully load to the vehicle (A/C ON, Blower ON with maximum
speed, Head Lamp ON, Wiper ON, and Other Lamps ON, etc.). |
7. | Select "Vehicle S/W Management". |
8. | Select "GPF Service Regeneration".


 |
1. | Turn ignition switch OFF and disconnect the battery negative (-) terminal. |
2. | Remove the exhaust gas temperature sensor (EGTS) #1, #2.
(Refer to Engine Control / Fuel System - "Exhaust Gas Temperature Sensor (EGTS)")
|
3. | Remove the GPF (C) after removing the installation nuts.
GPF installation nut :
39.2 - 58.8 N·m (4.0 - 6.0 kgf·m, 28.9 - 43.4 lb·ft) |
 |
4. | Install in the reverse order of removal. When installing, replace with new gaskets. |
|
•
| After replacing the GPF assembly, MUST perform the "Component Change Routine" procedure. |
|
1. | Turn ignition switch OFF. |
2. | Connect a KDS to Data Link Connector (DLC). |
3. | Turn ignition switch ON. |
4. | Select "Vehicle, Model year, Engine, System". |
5. | Start engine at idle and P-range (A/T) or neutral (M/T). |
6. | Apply
electrical fully load to the vehicle (A/C ON, Blower ON with maximum
speed, Head Lamp ON, Wiper ON, and Other Lamps ON, etc.). |
7. | Select "Vehicle S/W Management". |
8. | Select "Resetting Adaptive Values after GPF replacement".
