Rawze Dpf help

[scott]

Well, got couple dpf sensor codes. Even got the dreaded stop engine but it didn't flash. Turbo only builds 20 psi. Turbo replaced in July 2015 but not actuator. Presently, I sitting in shop lot and it letting me do parked regen. Probably gonna have actuator checked, to be safe.
Been doing regen for hour and half. First code was dpf temp sensor #3 Second code dpf preasure sensor #1. Drove it 35 mike to shop. As got within 12 mile it asked for parked regen.
Looking for guidance. Can't afford to have this truck down long. Dpf was replaced 2013 like 357,000 miles ago. First time it ever done this. What do I have checked etc. Isx 871. If helps I been in way south texas last week. Had to idle for a.c. it did blow some smoke on a slight hill before everything went crazy
