For those of you looking to replace your steering angle position sensor here is how you do such a task. This write up if for a 2007 Ford Edge, however may work on other years as well. It can be used as a guild for others even if items are in different locations.
First you will need a few tools.
Screw driver with T-20 Torx bit.
18MM socket wrench with extension. At least a 5" should be good.
Small flat head screw driver or knife.
A wire hanger straightened or a small allen head wrench driver.
First and most important disconnect your battery and leave it set for 30 minutes. This way you will not have any power stored in your driver side airbag which must be removed.
Take your T-20 torx and remove the three screws from the steering column.
Here is a better view of where they are located.
Now that your 30 minute wait is over remove the driver side air bag. There are two holes, one on either side of the steering wheel. Take your allen head wrench, straightend wire hanger or other tool to insert into these holes and depress the hidden clips. You can pull slightly on that side to make sure it has popped out successfully.
WARNING. Airbags are very dangerous if handle improperly and should be faced upward when removed and sat aside. Never hold the front of the airbag toward your person while handling the airbag if at all possible.
Now with the airbag detached you will have to remove the yellow and orange connectors. Be very careful not to damage these connectors and it could be costly to replace them. Use your small flat head screw driver or knife to pop the black retaining clips up. Very little effort is needed in this action. Once up the connectors will simply pull out with little effort.
Once that is done there is a black clip next to where the airbag wire are leading to. Simple push on the tab and slide it out. Sorry forgot the picture for this step.
With all the wires disconnected remove the steering wheel by taking your 18MM socket wrench and removing the center bolt. This can be seen in above airbag wire picture. After the bolt is removed it might take a little tugging to remove the wheel. Be careful of the wires fed through the steering wheel.
Simply tuck the wires left aside. You will notice another wire harness clipped in on the bottom side under the clock spring. Unclip this and just let it hang.
Now remove the two torx screws so you can remove the clock spring.
Now for the sensor. There is one last harness plug on the back side. Unclip it and let it hang.
Time to remove the last two screws.
If you bought the sensor new from ford it should be set with the locking clip in place. Remove the clip and be very careful not to turn the inner part of the sensor. If you do turn it back the way you did and align the arrows. Insert the new sensor and put everything back in the reverse order of removal and your done.
If you have any questions, comments or concerns let me know.
