Nissan Maxima Service and Repair Manual: Variable induction air system

Description

Power Valves 1 and 2
The power valves 1 and 2 are installed in intake manifold collector and used to control the suction passage of the variable induction air control system. They are set in the fully closed or fully opened position by the power valve actuators 1 and 2 operated by the vacuum stored in the vacuum tank. The vacuum to power valve actuators is controlled by the VIAS control solenoid valves 1 and 2.

Component Function Check

1.CHECK OVERALL FUNCTION-I

With CONSULT

  1. Start engine and warm it up to the normal operating temperature.
  2. Perform "VIAS S/V-1" in "ACTIVE TEST" mode with CONSULT.
  3. Turn VIAS control solenoid valve 1 "ON" and "OFF", and check that power valve actuator 1 rod moves.
