Discuss the causes and fixes for P0325 Scion OBDII Code
-
Have P0325 code that keeps coming in on 2005 Scion xA. Checked wiring harness to knock sensor- good, Replaced knock sensor- still coding. Main issue is car not shifting into OD. Flushed transmission oil and changed filter, still coding and not going into OD. Otherwise car runs great up to third gear.
-
The knock sensor will not cause the symptoms you have describe. The car not shifting into OD sounds more like a transmission mechanical problem.
