Default How to Clean PTC on a Volvo 850

What is the procedure to remove, clean and re-install the PTC? PTC is part of the PCV system?

Take out the intake hose i.e. the one from air filter box to the turbo inlet after disconnecting the electrical connector and 2 tubings from the PTC. Now once its out, carefully remove the PTC from the hose specially taking care of the rubber gromet that holds the PTC onto the intake hose and give it a nice flush with carb cleaner or brake cleaner. You might fint the narrow hole for one of the vaccum line blocked or abstructed. The installation process is just the reverse order of removal but I actually added 2 cable ties to hold the PTC on to the hose because the gromet was not in perfect condition and have also used some black sealent between gromet and hose.

Is it necessary to remove the intake hose? The PTC is clearly visible/accessible. from top.
