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.

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
B
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.
