3. Connect the test harness (2 pins)
1
to
the crank position sensor
2
, and then
measure the crank position sensor out-
put peak voltage.
CAUTION:
Check that the wiring harness does not
interfere with the flywheel magnet.
NOTE:
• If measuring the sensor output peak volt-
age under the
“ cranking ” and “ unloaded ”
conditions, disconnect the coupler
a
.
• If measuring the sensor output peak volt-
age under the
“ cranking ” and “ loaded ” con-
ditions, remove the clip from the engine
stop lanyard switch to prevent the engine
from starting.
• Check the crank position sensor air gap
and the condition of the projection on the
flywheel magnet if below specification.
4. Measure the crank position sensor resis-
tance.
NOTE:
Disconnect the test harness coupler
a
but
leave the harness connected to the crank
position sensor.
Checking the crank position sensor
air gap
1. Remove the wiring harness guide bolts
and lift up the wiring harness guide.
NOTE:
To completely remove the wiring harness
guide when checking the air gap, see Chap-
ter 4,
“ Reducing the fuel pressure ” and Chap-
ter 5, “ Removing the wiring harness. ”
2. Turn the flywheel magnet clockwise to
align the projection
a
on the flywheel
magnet with the crank position sensor
projection
b
.
3. Measure the crank position sensor air
gap
c
. Adjust if out of specification.
4. Loosen the crank position sensor screws
1
and adjust the crank position sensor
air gap.
