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. • Lift and support the fuel tank. (5-3) Green • 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 Black lead wire coupler. Tester knob indication: Voltage () CKP sensor peak voltage: 0.5 V and more (Green – Black) CKP sensor If the peak voltage is lower than the standard range, check each coupler coupler connection or replace the CKP sensor and inspect it GG again. BB CKP sensor Peak volt adaptor CKP SENSOR RESISTANCE E • Measure the resistance between the lead wires and ground. If L the resistance is not as specified, the CKP sensor must be CKP sensor replaced.
