Supersedes Technical Service Bulletin Group 01 number 13-45 dated December 5, 2013. The MIL is on. DTCs are stored in the ECM. Under extreme driving conditions (such as short-distance, stop-and-go driving), high crankcase pressure can cause the DTCs to appear.
The condition can be improved and the DTCs eliminated when the crankcase pressure valve is changed to a lower operating pressure and the ECM software is updated to compensate for new crankcase pressure.
