• Lift up the fuel tank. ( 4-51)
• Disconnect the CKP sensor lead wire coupler and connect the
multi circuit tester with the peak volt adaptor.
Green (+ Probe) – Blue (- Probe)
• Measure the CKP sensor peak voltage at the CKP sensor lead
wire coupler.

CKP sensor peak voltage:
If the peak voltage is lower than the standard range, check each
coupler at both ends of the circuit or replace the CKP sensor
and inspect it again.
CKP SENSOR RESISTANCE
• Measure the resistance between the lead wires and ground. If
the resistance is not specified value, the CKP sensor must be
replaced.
