Crankshaft Sensor Inspection
Remove the right frame cover (see Frame Cover Removal
in the Frame chapter).
Disconnect the crankshaft sensor lead connector [A].
Set the hand tester to the × 10 Ω range and connect (+)
lead to the yellow lead and (–) lead to the black lead in
Special Tool - Hand Tester: 57001-1394
Crankshaft Sensor Resistance:
Standard: 376 ∼ 564 Ω
If there is more resistance than the specified value, the
coil has an open lead and must be replaced. Much less
than this resistance means the coil is shorted, and must
Using the highest resistance range of the tester, measure
the resistance between the crankshaft sensor leads and
Any tester reading less than infinity (∞) indicates a short,
necessitating replacement of the crankshaft sensor as-
Crankshaft Sensor Peak Voltage Inspection
Be sure the battery is fully charged.
Using the peak voltage adapter [A] is a more reliable
way to determine the condition of the crankshaft sen-
sor than crankshaft sensor internal resistance measure-
Disconnect the crankshaft sensor lead connector (see
Crankshaft Sensor Removal).
Set the hand tester [B] to the × DC 10 V range, and con-
nect it peak voltage adapter.
Connect the black lead of the peak voltage adapter to
black lead and red lead to yellow lead in the crankshaft
Turn the ignition switch to ON and the engine stop switch
to run position.
Pushing the starter button, turn the engine 4 ∼ 5 sec-
onds with the transmission gear in neutral to measure the
crankshaft sensor peak voltage.
Repeat the measurement 5 times or more.
Crankshaft Sensor Peak Voltage
2.0 V or more

Peak Voltage Adapter: 57001-1415
If the tester reading is not the specified one, check the
crankshaft sensor (see Crankshaft Sensor Inspection).
