When replacing the CKP sensor with a new one, perform the CKP sensor learning value clearing procedure to clear the learning value stored in the PCM. If the stored learning value is not cleared, the engine performance may not function at its full capability. (See CKP SENSOR LEARNING VALUE CLEARING PROCEDURE .)
