where is the steering angle position sensor located on a 2013 ford fusion 2.5

on the rack and pinion assy.

Is it easy to reach and replace?

not in the best spot but yes replaceable.

I looked and there is no sensor on the rack

If its not located on top of rack.( were the steering shaft goes ) then its behind the steering wheel I believe as part of the clock spring.

I'm having the same problem. Mine is a 2010 Ford fusion sel 3.0. Electric power steering. Its not behind the wheel. I can't find where it could be on the rack and pinion

Where steering wheel angle located on ford fusions 2010
