To install: If the plastic locator cover is not attached to the replacement camshaft position sensor, attach a
synchro positioning tool, such as Ford Tool T89P-12200-A or equivalent. To do so, perform the
following: Engage the sensor housing vane into the radial slot of the tool.
1. 
Rotate the tool on the camshaft sensor housing until the tool boss engages the notch in the...

Transfer the oil pump intermediate shaft from the old camshaft position sensor housing to the
replacement sensor housing.
9. 
Install the camshaft sensor housing so that the drive gear engagement occurs when the arrow on the
locator tool is pointed approximately 7° counterclockwise (the sensor terminal connector should be
aligned with its matchmarks) from the face of the cylinder block.

Remove the sensor retaining screw and the sensor from the left-hand valve cover.
3. 
To install: Make sure the camshaft position sensor mounting surface is clean and the O-ring is positioned
correctly.
4. 
Position the sensor, then install the retaining screw and tighten it to 71-106 inch lbs. (8-12 Nm).

... then unbolt the sensor and pull it away from the engine-crankshaft damper removed for
clarity
To install:
When installing a new sensor on the 4.0L (VIN X and E), position the sensor against the crankshaft
damper. There are small rub tabs which wear off and allow the sensor to be perfectly spaced from the

Vehicle Speed Sensor(VSS) HOW TO USE THIS BOOK
Vehicle Speed Sensor(VSS) 565 

OPERATION
The Vehicle Speed Sensor (VSS) is a magnetic pick-up that sends a signal to the Powertrain Control Module
(PCM). The sensor measures the rotation of the transmission and the PCM determines the corresponding
vehicle speed.
TESTING Turn the ignition switch to the OFFposition.
1. 
Disengage the wiring harness connector from the VSS.
2. 
Using a Digital Volt-Ohmmeter (DVOM), measure the resistance (DVOM ohmmeter function)
between the sensor terminals. If the resistance is 190-250 ohms, the sensor...
