HINT: 

Make sure that the connector is properly connected. If it is not, securely connect it and check for DTCs again.

1. Disconnect the crankshaft position sensor connector.
2. Turn the engine switch on (IG).
3. While jiggling the ECM connector, measure the voltage according to the table below.

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   Z4-3 (VCNE) - Body ground	Engine switch on (IG)	4.5 to 5.5 V
   Z4-1 (NE+) - Body ground	Engine switch on (IG)	3.0 to 5.0 V

   HINT: 

   By jiggling the connector while performing the inspection, it is possible to confirm that the terminals are contacting with sufficient pressure.

4. Turn the engine switch off.
5. While jiggling the ECM connector, measure the resistance according to the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   Z4-2 (NE-) - Body ground	Engine switch off	Below 1 Ω

   HINT: 

   By jiggling the connector while performing the inspection, it is possible to confirm that the terminals are contacting with sufficient pressure.
