Estimated Leak (Mm)

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2014 Volvo XC90, 2013 Volvo XC90, 2012 Volvo XC90, 2011 Volvo XC90, and 2010 Volvo XC90. However, it is still accessible from the selected car via links, so may be relevant.

The value shows the diameter of the leak. The Engine control module (ECM) calculates the diameter with the help of measurements made during testing.

HINT: The parameter should be used to get an understanding of how close to the diagnostic trouble code limit the system is. If the estimated size of the leak is very close to the diagnostic trouble code limit, fault tracing should probably be carried out despite the test result for the tank system showing "No leakage found", especially if the diagnostic trouble code (DTC) for leakage was initially generated.
