CHECKING THE CRANKSHAFT POSITION
SENSOR
1. Disconnect:
• Crankshaft position sensor coupler
(from the wire harness)
2. Check:
• Crankshaft position sensor resistance
Out of specification → Replace the crank-
shaft position sensor.
a. Connect the digital circuit tester (Ω) to the
crankshaft position sensor coupler as
shown.
b. Measure the crankshaft position sensor re-
sistance.

CHECKING THE STARTER MOTOR
OPERATION
1. Check:
• Starter motor operation
Does not operate → Perform the electric
starting system troubleshooting, starting with
step (4).
Refer to “TROUBLESHOOTING” on page 8-
15.
a. Connect the positive battery terminal “1”
and starter motor lead “2” with a jumper
lead “3”.
WARNING
EWA13810
• A wire that is used as a jumper lead must
have at least the same capacity of the bat-
tery lead, otherwise the jumper lead may
burn.
• This check is likely to produce sparks,
therefore, make sure no flammable gas or
fluid is in the vicinity.
b. Check the starter motor operation.
