1. Disconnect the camshaft position sensor (for intake camshaft) connector.
2. Turn the engine switch on (IG).
3. Measure the voltage according to the value(s) in the table below.

   Standard Voltage

   Tester Connection	Condition	Specified Condition
   C51-3 (VC) - Body ground	Engine switch on (IG)	4.5 to 5.5 V
   C51-1 (VVI+) - Body ground	Engine switch on (IG)	3.0 to 5.0 V

4. Turn the engine 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
   C51-3 (VC) - C51-1 (VVI+)	Engine switch off	1.425 to 1.575 kΩ
   C51-2 (VVI-) - Body ground	Always	Below 1 Ω
