Long term fuel trim

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2009 Volvo S60, 2008 Volvo S60, 2007 Volvo S60, 2006 Volvo S60, and 2005 Volvo S60. However, it is still accessible from the selected car via links, so may be relevant.

Long term fuel trim is slow adjustment of the fuel trim value that is used to adapt the fuel / air mixture during longer periods. This value takes into consideration factors such as the aging of components and component tolerances etc. The area of adjustment is between 0-2. The normal value is 1 (no adaptation).
