6) 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.
7) 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: 1.5 V and more
! 09900-25008: Multi-circuit tester set
& Tester knob indication: Voltage (')
.
Is the voltage OK?
• G/W or G/BI wire open or shorted to ground.
• Loose or poor contacts on the CKP sensor cou-
pler or ECM coupler (terminal D or U).
• If wire and connection are OK, intermittent trou-
YES ble or faulty ECM.
• Recheck each terminal and wire harness for
open circuit and poor connection.
• Replace the ECM with a known good one, and
inspect it again.
• Inspect that metal particles or foreign material
stuck on the CKP sensor and rotor tip.
NO • If there are no metal particles and foreign mate-
rial, then replace the CKP sensor with a new
one.
3) After repairing the trouble, clear the DTC using SDS tool.
