Hi

996 C2 MY99

I have a loose resonance tube control solenoid, and I don´t know where the two vacuum tubes are connected. One is straight, and the other one has a 180º bent on it.

The solenoid is the one which is NOT the gadget which is fixed to the resonance tube, but rather near the throttle body

Pls help!

Thanks guys

Kare

The nipple that comes out straight from the solenoid goes to the vacuum reserve tank under the intake on the left side. To test this connection, there should be a vacuum when the engine is running. The other tube coming out of the right angled nipple goes directly to the butterfly valve on the back intake tube. You can test this connection by apply suction to the tube and you will hear the butterfly move.

This solenoid is attached to a clip above and behind the alternator.
