Park / Neutral Position (PNP) Function

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 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.
