      *a Component without harness connected
      (Cam Timing Oil Control Solenoid Assembly LH)
      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance

        Tester Connection Condition Specified Condition
        D13-1 - D13-2 0 °C (32 °F) 6.3 to 7.3 Ω
        D13-1 - D13-2 20 °C (68 °F) 6.9 to 7.9 Ω
        D13-1 - D13-2 40 °C (104 °F) 7.4 to 8.6 Ω

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

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

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

        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

        4.3 mm (0.169 in.) or more

        HINT: 

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

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