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

Diagnosis Procedure
1.INSPECTION START
Confirm the malfunctioning system (power valve 1 or power valve 2).
2.CHECK VACUUM EXISTENCE-I
With CONSULT
- Stop engine and disconnect vacuum hose connected to power valve
actuator 1.
- Start engine and let it idle.
- Perform "VIAS S/V-1" in "ACTIVE TEST" mode with CONSULT.
- Turn VIAS control solenoid valve 1 "ON" and "OFF", and check
vacuum existence under the following conditions.

Without CONSULT
- Stop engine and disconnect vacuum hose connected to power valve
actuator 1.
- Disconnect VIAS control solenoid valve 1 harness connector.
- Start engine.
- When revving engine up to 5,000 rpm quickly.
- Check vacuum existence under the following conditions.

3.CHECK VACUUM TANK
- Stop engine and disconnect vacuum hose connected to intake
manifold collector.
- Start engine and let it idle.
- Check vacuum existence from intake manifold collector.
4.CHECK VACUUM HOSE
- Stop engine.
- Check vacuum hose for cracks, clogging, improper connection
or disconnection.
