Toyota calls it the "vacuum transmitting valve". It may be some sort of a check valve or one-way valve.

Part 23283 in the diagram (Mid-upper-center of the diagram)

Part no.: 90925-01091 - VALVE, VACUUM TRANSMITTING, NO.3

VACUUM PIPING[ (925- )2E ] TOYOTA COROLLA [AE1#,EE1] (ASIA and MIDDLE EAST)





Function and testing:

[dr. d]

still can't see, where it connects to...

efi na lang!

heh heh.

[oj88]

It's part of the emissions system. Here's another diagram, not from a 2E but it serves the same function.

It's the part indicated as "VTV" for Vacuum Transmitting Valve.

[dr. d]

i'll just file it under "one-way valve".

[oj88]

i'll just file it under "one-way valve".

Generally speaking, yes. Technically, no. It should flow unrestricted in one direction and slightly restricted in the other. How slightly restricted is dependent on the intended use. The engine vacuum varies widely during operation and certain pneumatic devices controlled by vacuum needs just the right amount to work properly.



Somebody can probably explain it more eloquently:

In one direction the VTV's are supposed to restrict, but NOT prevent flow. In the other direction, it should allow unrestricted air flow. If the flow one way is stopped, then the emissions system the VTV is associated with won't work properly.

Many thanks mga sir. VTV pala yon. Di ko pa masyado maintindihan pero sa emission systems pala yon, di naman pala input to engine or anywhere. Kaya siguro umaandar naman kahit putol. Palitan ko na lang if may mahanap na pamalit.
Salamat po ulit.

Good move. Make sure it’s the same specs. They all look the same but I think they are color coded. Make sure you install the correct one.

Oo nga sir. Thanks.
