HINT: 

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

1. Disconnect the VVT sensor (for intake camshaft) connector.
2. Turn the ignition switch to ON.
3. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   C16-3 (VC) - Body ground	Ignition Switch ON	4.5 to 5.5 V
   C17-3 (VC) - Body ground	Ignition Switch ON	4.5 to 5.5 V
   C16-1 (VVR+) - Body ground	Ignition Switch ON	3.0 to 5.0 V
   C17-1 (VVL+) - Body ground	Ignition Switch ON	3.0 to 5.0 V

4. Turn the ignition switch off and wait for at least 30 seconds.
5. Measure the resistance according to the value(s) in the table below.

   Standard Resistance

   Tester Connection	Condition	Specified Condition
   C16-3 (VC) - C16-1 (VVR+)	Ignition switch off	1.425 to 1.575 kΩ
   C17-3 (VC) - C17-1 (VVL+)	Ignition switch off	1.425 to 1.575 kΩ
   C16-2 (VVR-) - Body ground	Always	Below 1 Ω
   C17-2 (VVL-) - Body ground	Always	Below 1 Ω
