Q: P2002 DTC Particulate Trap Efficiency Below Threshold

Approximately 3 months ago a cracked Charged Air Hose was replaced after a P2002 and simultaneous turbocharger related code (don't have dtc). The car was code free for three months and 7000 miles. The P2002 code returned and was cleared numerous times. The code returns within either a few trips or up to two weeks. U144F00, P261F71. P13E77B were found once as pending codes on the ECU with a scanner. Simultaneously, the P2A00 code (O2 Sensor Circuit Range/Performance) was found once as a pending code. The DPF has been removed from the vehicle, inspected, cooked in a kiln, blown clean with compressed air and reinstalled. The vehicle has since been driven 5000 miles and continues to have P2002 codes intermittently. The DPF has successfully performed at least 2 regens since the off vehicle cleaning. The differential pressure sensor has been monitored while driving with the scanner. Pre and post dpf values differ from 0 to 3 psi. What do the undefined dtc's mean and how to resolve P2002?
