DIAGNOSIS PROCEDURE

Step Check Yes No
1 CHECK HARNESS BETWEEN CRANKSHAFT POSITION SENSOR AND ECM CONNECTOR. 
  1. Turn the ignition switch to OFF.
  2. Disconnect the connector from crankshaft position sensor.
  3. Measure the resistance of harness between crankshaft position sensor connector and engine ground.

    Connector & terminal 

    (E10) No. 1 - Engine ground: 

Is the resistance more than 100kΩ? Repair the harness and connector.
NOTE: In this case, repair the following item:
  • Open circuit of harness between crankshaft position sensor and ECM connector
  • Poor contact in ECM connector
  • Poor contact of coupling connector
Go to step 2. 
2 CHECK HARNESS BETWEEN CRANKSHAFT POSITION SENSOR AND ECM CONNECTOR. 
Measure the resistance of harness between crankshaft position sensor connector and engine ground.
Connector & terminal 
(E10) No. 1 - Engine ground: 
Is the resistance less than 10 Ω? Repair the ground short circuit of harness between crankshaft position sensor and ECM connector.
NOTE: The harness between both connectors are shielded. Repair the ground short circuit of harness with shield.
Go to step 3. 
3 CHECK HARNESS BETWEEN CRANKSHAFT POSITION SENSOR AND ECM CONNECTOR. 
Measure the resistance of harness between crankshaft position sensor connector and engine ground.
Connector & terminal 
(E10) No. 2 - Engine ground: 
Is the resistance less than 5 Ω? Go to step 4.  Repair the harness and connector.
NOTE: In this case, repair the following item:
  • Open circuit of harness between crankshaft position sensor and ECM connector
  • Poor contact in ECM connector
  • Poor contact of coupling connector
4 CHECK CONDITION OF CRANKSHAFT POSITION SENSOR.  Is the crankshaft position sensor installation bolt tightened securely? Go to step 5.  Tighten the crankshaft position sensor installation bolt securely.
5 CHECK CRANKSHAFT POSITION SENSOR. 
  1. Remove the crankshaft position sensor.
  2. Measure the resistance between connector terminals of crankshaft position sensor.

    Terminals No. 1 - No. 2: 

Is the resistance between 1 and 4 kΩ? Repair the poor contact of crankshaft position sensor connector. Replace the crankshaft position sensor. < Ref. to CRANKSHAFT POSITION SENSOR . >
