Park / Neutral Position (PNP) Function

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.

The gear-shift position sensor has a park / neutral position (PNP) function to prevent the engine being started with a gear selected.

This function prevents the engine being started unless the P or N positions are selected. This prevents the car from lurching forwards when started.
