Purge TVS

I don't know exactly what the PURGE TVS looks like. I'm replugging in all my emissions hoses and . I also need to know what the efe tvs and the air management valve looked like. Any pics/info would be greatly appreciated.

Eddie.

TVS on the left is a general picture. They pretty much all look alike.

On the right is the A.I.R. control valve.

Yes the TVS is near thermostat and its blue "have seen green too"
And dont confuse the A.I.R. control/mgmt valve with the Canister Control Valve they are pretty similar both, the TVS goes with 2 tubes to the Canister Control Valve. //Sorry for my bad English =)

The TVS's are on the intake manifold. And, yes, there are two control valves, the A.I.R. valve, and the canister purge control valve.

Look on the FAQ forum for a thread about vacuum diagrams. It shows the routing and relative locations of the various parts. The diagram originally was under the hood of your car, but are often destroyed for one reason or another.
