ELECTRICAL SYSTEM 9-27
CKP SENSOR PEAK VOLTAGE
• Remove the front seat. (8-7)
NOTE:
Be sure that all couplers are connected properly and the battery
used is in fully-charged condition.
• Disconnect the both couplers 1.
• Connect the multi-circuit tester with peak volt adaptor as fol-
lows.
• Measure the CKP sensor peak voltage between Orange/Blue
and Green/White lead wires at the ECM coupler (Black) A.

• Shift the transmission into the neutral and turn ignition switch
“ON”.
• Crank the engine a few seconds with the starter motor by
depressing starter button and check the CKP sensor peak
voltage.
• Repeat the above test procedure a few times and measure
the highest peak voltage.
Tester knob indication: Voltage ()
CKP sensor peak voltage: 0.28 V and more
(Orange/Blue – Green/White)
* Before using the multi-circuit tester and peak volt
adaptor, be sure to refer to the appropriate instruc-
tion manual.
* Normally, use the needle pointed probe to the back-
side of the lead wire coupler to prevent the terminal
bend and terminal alignment.
