    NO >>

    Replace EVT control solenoid valve. Refer to Exploded View.

  2. CHECK EVT CONTROL SOLENOID VALVE-2

    1. Remove EVT control solenoid valve. Refer to Exploded View.

    2. Provide battery voltage between EVT control solenoid valve terminals 1 and 2, and then interrupt it. Check that the plunger moves as shown in the figure.

      CAUTION:

      Do not apply battery voltage continuously for 5 seconds or more. Doing so may result in damage to the coil in EVT control solenoid valve.
