1) Turn the ignition switch OFF.
2) Disconnect the ECM coupler. Refer to “ECM Removal
and Installation in Section 1C (Page 1C-1)”.
3) Insert the needle pointed probes to the lead wire coupler.
4) Check there is continuity between the W wire “A” and
ECM terminal “27”. Also, there is no continuity among
the W wire “A” and ECM terminals.
Special tool
(A): 09900–25008 (Multi-circuit tester set)
(B): 09900–25009 (Needle pointed probe set)

Is the resistance OK?
Replace the ECM with a
new one. Refer to “ECM
Removal and
Installation in Section
1C (Page 1C-1)”.
• Inspect that metal
particles or foreign
material stuck on the
CKP sensor and rotor
tip.
• If there are no metal
particles and foreign
material, then replace
the CKP sensor with
a new one. Refer to
