If excessive black smoke is discharged by CPF system and Engine control system malfunction. CPF would be damaged by excessive black smoke.
If MIL (Malfunction Indicator Lamp) is blinked and poor acceleration is occurred simultaneously, There is a fatal damage in the CPF system.
First of all, Check DTC related with CPF system.
Inspect physical damage of the CPF visually, after checking intake/exhaust system leakage, EGTS (Exhaust Gas Temperature Sensor) malfunction, DPS (Differential Pressure Sensor) malfunction related with CPF.
IG KEY 'ON', ENGINE 'OFF'
Connect GDS(scantool) to Data Link Connector (DLC).
Monitor engine system DTCs related with CPF.
P0299 : Turbo/Super charger underboost condition
P0472 : Exhaust differential pressure sensor circuit malfunction - High input
P0473 : Exhaust gas differential pressure sensor high
P1405 : CPF - Permanent regeneration
P1406 : Exhaust gas temperature not plausible between calculated and simulated
P1407 : Plausibility of temperature calculated and simulated upstream of particulate filter
P2002 : Particulate Trap Efficiency below threshold
P2033 : Exhaust gas temperature sensor circuit high (Bank1 / Sensor2)
P2032 : Exhaust gas temperature sensor circuit low (Bank1 / Sensor2)
