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. (4-27) Step 2 2 1) Crank the engine a few seconds with the starter motor, and V measure the CKP sensor peak voltage at the coupler. 2) Repeat the above test procedure a few times and measure E the highest peak voltage.
