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 ignition switch to ON.
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	Ignition switch ON	4.5 to 5.5 V
   Z4-1 (NE+) - Body ground	Ignition switch ON	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 ignition 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	Ignition 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.
