CRANKSHAFT POSITION SENSOR TEST—8.0L
V-10 ENGINE
The crankshaft position sensor is located on the
right-lower side of the cylinder block, forward of the
right engine mount, just above the oil pan rail (Fig.
5).

To perform a complete test of this sensor and its
circuitry, refer to the DRB scan tool. Also refer to the
appropriate Powertrain Diagnostics Procedures man
ual. To test the sensor only, refer to the following:
(1) Raise and support the vehicle.
(2) Disconnect the sensor pigtail harness from the
main engine wiring harness connector.
(3) Place an ohmmeter across terminals B and C
(Fig. 3). Ohmmeter should b e set to lK-to-lOK
scale for this test. The meter reading should be
open (no resistance). Replace sensor if a low resis
tance is Indicated.

INSPECTION
Remove the distributor cap and wipe it clean with
a dry lint free cloth. Visually Inspect the cap for
cracks, carbon paths, broken towers, or damaged ro
tor button (Figs. 6 and 7). Also check for white depos
its on the Inside (caused by condensation entering
the cap through cracks). Replace any cap that dis
plays charred or eroded terminals. The inside flat
surface of a terminal end (faces toward rotor) will in
dicate some evidence of erosion from normal opera
tion. Examine the terminal ends for evidence of
mechanical interference with the rotor tip.
