Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

I dont show a 4.9 liter engine in this model here but do show a 4.7 and assume this is the engine you have.If it is not let me know.Below is the procedure on how to replace the crank sensor on the 4.7 liter engine in this model here.

https://www.dropbox.com/s/m798h3mmm9c1tv0/c-08-23.gif?dl=0

The Crankshaft Position (CKP) sensor is bolted to the side of the engine cylinder block above the starter motor. It is positioned into a machined hole at the side of the engine block.
1. Remove starter motor. (if you need info on this let me know as well)
2. Disconnect CKP electrical connector at sensor.

3. Remove CKP mounting bolt.
4. Carefully pry sensor from cylinder block in a rocking action with two small screwdrivers.
5. Remove sensor from vehicle.
6. Check condition of sensor O-ring.

INSTALLATION
1. Clean out machined hole in engine block.
2. Apply a small amount of engine oil to sensor O-ring.
3. Install sensor into engine block with a slight rocking action. Do not twist sensor into position as damage to O-ring may result.

CAUTION: Before tightening sensor mounting bolt, be sure sensor is completely flush to cylinder block. If sensor is not flush, damage to sensor mounting tang may result.

4. Install mounting bolt and tighten to 28 Nm (21 ft. lbs.) torque.
5. Connect electrical connector to sensor,
6. Install starter motor.
