5) If OK, then check the continuity between each terminal and
ground.
CKP sensor continuity: ∞ Ω (Infinity)
\ 09900-25008: Multi-circuit tester set
V 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 CKP sensor
coupler and ECM coupler.
2) Repeat the above test procedure a few times and measure
the highest peak voltage.
CKP sensor peak voltage: 0.5 V and more (

.
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
• 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.
