DIAGNOSTIC PROCEDURE

Step	Check	Yes	No
1 CHECK INSTALLATION 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. < Refer to INSTALLATION , Crankshaft Position Sensor. >
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. Terminals No. 1 - No. 2:	Is the resistance between 1 and 4 kΩ?	Go to step 3 .	Replace the crankshaft position sensor. < Refer 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 and crankshaft position sensor connector. Connector & terminal (B137) No. 17 - (E10) No. 1: (B137) No. 25 - (E10) No. 2:	Is the resistance less than 1 Ω?	Repair the poor contact of ECM and crankshaft position sensor connector.	Repair the harness and connector. NOTE: In this case, repair the following item: Open circuit in harness between ECM and crankshaft position sensor connector Poor contact of coupling connector
