Air Management System

AIR Induction Valve:

AIR INDUCTION VALVE/REED VALVE

1. Remove AIR induction valve.
2. Blow into inlet side of valve. Little or no air should pass through the valve.
3. Apply vacuum to the control port of the induction valve. Check that the diaphragm holds vacuum without leaking.
4. With vacuum still applied, blow into inlet side of valve. Air should flow freely through valve.
5. Still applying vacuum, blow into exhaust side of induction valve. No air should pass through valve from exhaust side to inlet side.
6. Replace if defective.

Vacuum Switching Valve:

VACUUM SWITCHING VALVE

1. Remove VSV.
2. Connect vacuum pump to port B.
3. Block port A with finger tip and apply vacuum to port B. No vacuum should be felt at port A, and port B should be vented to the atmosphere (does not hold vacuum).
4. Energize solenoid by applying 12 volts DC.
5. Block port A with finger tip and apply vacuum to port B. You should feel vacuum at port A and valve should hold vacuum until port A is opened.
6. Replace if defective.

NOTE: When re-installing VSV, be sure port B is connected to device and port A is connected to vacuum source. If connected improperly, a vacuum leak will result.

Vacuum Delay Valve:

VACUUM DELAY VALVE

1. Remove valve.
2. Check that air flows freely through valve from B to A, and is restricted when flowing from A to B.
