HINT: 

Use the same procedure for the intake side and exhaust side.

1. Check the resistance.
   1. Measure the resistance according to the value(s) in the table below.

      *a	Component without harness connected (Cam Timing Oil Control Solenoid Assembly)
      *b	Intake Side
      *c	Exhaust Side

      Standard Resistance

      Tester Connection	Condition	Specified Condition	Result
      D6-1 (-) - D6-2 (+)	0°C (32°F)	6.3 to 7.3 Ω	Ω
      D6-1 (-) - D6-2 (+)	20°C (68°F)	6.9 to 7.9 Ω	Ω
      D6-1 (-) - D6-2 (+)	40°C (104°F)	7.4 to 8.6 Ω	Ω
      D8-1(-) - D8-2(+)	0°C (32°F)	6.3 to 7.3 Ω	Ω
      D8-1(-) - D8-2(+)	20°C (68°F)	6.9 to 7.9 Ω	Ω
      D8-1(-) - D8-2(+)	40°C (104°F)	7.4 to 8.6 Ω	Ω

      If the result is not as specified, replace the cam timing oil control solenoid assembly.

2. Check the shaft stroke.
3. Stroke Amount Inspection
   1. Using vernier calipers, measure length (A) and (B) with the shaft of the cam timing oil control solenoid assembly set in the respective positions shown in the illustration.
      NOTE:

      Do not apply auxiliary battery voltage to the terminals of the cam timing oil control solenoid assembly.

      HINT: 

      If the shaft does not extend under its own weight, extend the shaft with your fingers.

      *a	Shaft Side Facing Down
      *b	Shaft Side Facing Up
      *c	Shaft

   2. Calculate the stroke amount based on the difference of length (A) and (B).

      Standard

      Specified Condition	Result
      4.3 mm or higher 0.169 in. or higher	mm in.

      HINT: 

      Stroke amount = length (A) - length (B)

      If the value is not as specified, replace the cam timing oil control solenoid assembly.
