Camshaft Sensor Depth, Check
The signal from the camshaft sensor must
exceed 0.5 volt in order to start the engine. If the
signal is low, check the depth setting of the
sensor following this procedure.
1. Remove the plug from the flywheel housing
and install the appropriate flywheel turning
tool, 9996956 (MP7) or 88800014 (MP8 and
MP10).
2. Check for proper camshaft position sensor
clearance using the sensor depth gauge,
88800031, to determine if shims are
required for sensor depth.

Figure 48 — Using Gauge at Camshaft Sensor Location
a. Rotate the engine until a tooth of the
camshaft toothed wheel is aligned with
the sensor bore.
b. Insert the depth gauge into the sensor
bore until the outer part of the gauge is
fully seated against the timing gear
cover.
c. Loosen the thumb screw of the gauge
and push the inner part of the gauge in
until it contacts a tooth of the toothed
wheel.
d. Tighten the thumb screw to secure the
inner part of the gauge.
e. Carefully remove the gauge from the
camshaft sensor bore and observe the
location of steps between the inner and
outer portions of the gauge (Figure 49):
앫 Both steps below the surface of
the gauge = no shims required.
앫 One step below the surface of the
gauge = one shim required.
앫 Both steps above the surface of
the gauge = two shims required.

3. Install the camshaft position sensor with the
appropriate shim(s) and new O-ring. Secure
the sensor with a bolt and plug in the
harness connector.
