Volvo: Volvo S 70 boost sensor, volvo s 70, wastegate actuator

Question
Hi

Please can you assist with the routing of the three pipes on the boost sensor. The three pipes on the sensor are marked R C W. Does it stand for Return ( to ambient ) Compcover ( Turbo ) & Wastegate ( Actuator on Turbo )

Regards

Answer
Gean,
The only info that I have said the yellow marked hose to the waste gate and the center to the bypass, and that tells me the one that is left goes to the air filter tube. Reading the replacement of the valve only states to remove hose and relace carefully on the same (like) connectors. Some cars have a sticker under the hood showing the vacuum routings. Look under side of hood.
