Go to Step 4. Go to Step 3.
3 CKP Sensor Resistance check :
1) With ignition switch OFF, disconnect CKP
sensor coupler.
2) Check resistance between “WHT” wire ter-
minal and “RED” wire terminal of CKP sen-
sor coupler.
Is the resistance 485 – 655
Ω
?
Faulty “WHT/BLU” wire or
“ORN/BLU” wire. Faulty CKP sensor.
4 CKP Sensor Visual inspection :
1) Check CKP sensor installation and teeth of
crankshaft referring to “Timing Chain Cover”
in Section 6A2.
Are they OK?
Poor C51-3-2 and/or C51-
