Step	Check	Yes	No
1 CHECK CONDITION OF CRANKSHAFT POSITION SENSOR.	Is the crankshaft position sensor installation bolt tightened securely?	Go to step 2.	Tighten the crankshaft position sensor installation bolt securely.
2 CHECK CRANKSHAFT POSITION SENSOR. Turn the ignition switch to OFF. Remove the crankshaft position sensor. Measure the resistance between terminals of crankshaft position sensor connector. Terminals No. 1 - No. 2:	Is the resistance between 1 and 4 kΩ?	Go to step 3.	Replace the crankshaft position sensor. <Ref. to CRANKSHAFT POSITION SENSOR .>
3 CHECK HARNESS BETWEEN ECM AND CRANKSHAFT POSITION SENSOR CONNECTOR. Disconnect the connector from ECM. Measure the resistance of harness between ECM connector and crankshaft position sensor connector. Connector & terminal (E158) No. 40 - (E10) No. 1: (E158) No. 27 - (E10) No. 2:	Is the resistance less than 1 Ω?	Repair the poor contact of ECM and crankshaft position sensor connector.	Repair the open circuit in the harness between the ECM connector and crankshaft position sensor connector.
