  1. Connect the intake actuator connector.
  2. Turn the ignition switch ON.
  3. Check the voltage between terminal 5 and 6.

* It will feedback the current position of the actuator to controls.

* It will feedback the current position of the actuator to controls.

  1. If the intake actuator does not operate well, substitute with a known-good intake actuator and check for proper operation.
  2. Replace the intake actuator if it is proved that there is a problem with it.

Replacement
