Hope this helps you..
Apply a small amount of engine oil to the sensor o-ring.
A low (step down) and high (step up) area are machined into the camshaft drive gear. The sensor is positioned in the timing gear cover so that a small air gap exists between the face of sensor and the high machined area of cam gear.
Before the sensor is installed, the cam gear may have to be rotated. This is to allow the high machined area (step up) on the gear to be directly in front of the sensor mounting hole opening on the timing gear cover.
Do not install sensor with gear positioned at low area. When the engine is started, the sensor will be broken.
Using a 1/2 in. wide metal ruler, measure the distance from the cam gear to the face of the sensor mounting hole opening on the timing gear cover.
If the dimension is approximately
1–15/32 inches or less, it is OK to install sensor.
If the dimension is approximately 1–5/8 inches or more, the cam gear will have to be rotated.
Attach a socket to the vibration damper mounting bolt and rotate engine until the
1–15/32 inch dimension is attained.
Install the sensor into the timing case/cover with a slight rocking action. Do not twist the sensor into position as damage to the o-ring may result. Push the sensor all the way into the cover until the rib material on the sensor contacts the camshaft gear.
Install the mounting bolt and tighten to 10.7 N·m (95 in. lbs.) torque.
Connect sensor wiring harness to engine harness.
When the engine is started, the rib material will be sheared off the face of sensor. This will automatically set sensor air gap.
