Under extreme driving conditions, such as a driving profile of mainly short distance \(stop and go\) driving high crankcase pressure can lead to the above described DTC codes. By changing the crankcase pressure valve to a lower operating pressure this condition can be improved and eliminate the mentioned possible DTC codes. Along with the crankcase pressure being lowered, a new ECM software level is required to compensate for new crankcase pressure.
