9-28 ELECTRICAL SYSTEM
If the peak voltage is lower than the standard range, check the
peak voltage at the CKP sensor lead wire coupler.
• Remove the front seat. (8-7)
• Lift and support the fuel tank. (5-3)
• Disconnect the CKP sensor lead wire coupler and connect the
multi-circuit tester with the peak volt adaptor.
Black wire (+ Probe) – Green wire (- Probe)
• Measure the CKP sensor peak voltage at the CKP sensor
lead wire coupler.
Tester knob indication: Voltage ()
CKP sensor peak voltage: 0.28 V and more
(Green – Black)
If the peak voltage is lower than the standard range, check each
coupler connection or replace the CKP sensor and inspect it
again.
If the peak voltage is within the specification, check the continu-
ity between the CKP sensor coupler and ECM coupler.
CKP SENSOR RESISTANCE
• Measure the resistance between the lead wires and ground. If
the resistance is not as specified, the CKP sensor must be
replaced.

Tester knob indication: Resistance (Ω)
CKP sensor resistance: 142 – 194 Ω (Green – Black)
