Malfunction Threshold
The ratio of the current EGR flow to the normal EGR flow is 15 % or less for at least 3.0 seconds.
The ratio is derive from the actual and estimated MAP values that are each difference between before and after the EGR valve was opened.
The estimation MAP difference value is applied in the table.
