5) If OK, then check the continuity between each terminal and
ground.
 CKP sensor continuity: ∞ Ω (Infinity)
 09900-25008: Multi-circuit tester set
 Tester knob indication: Resistance (Ω)
Are the resistance and continuity OK?
YES Go to step 2.
NO Replace the CKP sensor with a new one.
6) After repairing the trouble, clear the DTC using SDS tool.

Step 2
1) Crank the engine a few seconds with the starter motor, and
measure the CKP sensor peak voltage at the coupler.
2) Repeat the above test procedure a few times and measure
the highest peak voltage.
 CKP sensor peak voltage: 2.0 V and more
