2005 Jeep Liberty CRD 79,000 miles
Error Codes:
P0299 Underboost Turbo
P1189 (This is not a code for a CRD)

My Neighbor has a fairly new scanner but it didn't have the 2.8L CRD listed under Jeep models. Still this is what he told me the codes were.

Liberty has no power for acceleration after about 20 mph.

Any suggestions would be appreciated

P1189 is the small sensor in the side of the air filter lid.

Underboost can be caused by:
Leaking intercooler hoses
Bad or dirty MAP sensor
Bad turbo control vacuum solenoids
Stuck turbo vanes
Bad turbo
