ELECTRICAL SYSTEM 9-25
CKP SENSOR PEAK VOLTAGE
NOTE:
Be sure that all couplers are connected properly and the battery
used is in fully-charged condition.
• Remove the right frame cover. (
8-4)
• Disconnect the CKP sensor coupler
1
and connect the multi
circuit tester with the peak volt adaptor as follows.
G terminal (
+
Probe) – B terminal (
-
Probe)
09900-25008: Multi circuit tester set
NOTE:
Before using the multi circuit tester and peak volt adaptor, be
sure to refer to the appropriate instruction manual.
• Measure the CKP sensor peak voltage at the CKP sensor
lead wire coupler.
• Shift the transmission into neutral, turn the ignition switch ON
and grasp the clutch lever.
• Press the starter button and allow the engine to crank for a
few seconds, and then measure the CKP sensor peak volt-
age.
• Repeat the above test procedure a several times and mea-
sure the highest peak voltage.
Tester knob indication: Voltage (
)
CKP sensor peak voltage: 1.5 V or more (Green – Black)
If the peak voltage is within the specification, check the continu-
ity between the CKP sensor coupler and ECM coupler.
CKP SENSOR RESISTANCE
• Disconnect the CKP sensor coupler
1
. (
above)
• Measure the resistance between the lead wires and ground. If
the resistance is not within the standard range, replace the
CKP sensor with a new one.
09900-25008: Multi circuit tester set
Tester knob indication: Resistance (
)
CKP sensor resistance: 150 – 230
(Black – Green)
(Blue – Ground)
Normally, use the needle-pointed probe to the back-
side of the lead wire coupler to prevent the terminal
bend and terminal alignment.
