Range Selection: Notes

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

The PCM receives the range selector position by monitoring 2 independent voltage signals from the Transmission Range (TR) sensor. The TR  voltages are then compared to an allowed voltage range for each gear.
