Water which enters the active carbon canister through the extended air inlet hose (arrow 1) may impede fuel tank venting and could freeze in winter
weather. If this happens, the fuel tank could collapse and the engine performance could possibly be impaired.
If this condition is found when repairing, proceed as follows:
^
Remove the left front wheel house lining and disconnect the extended air inlet hose at the coupling (arrow 2).
^
Tape over the end of the disconnected air inlet hose. Secure hose out of the way with a tie-wrap. Complete removal of the extended hose is not
necessary.
^
Reinstall wheel house lining.
Note:
A frozen active carbon canister must be replaced.
The extended inlet air hose was discontinued in 944S production from the following VIN:
94 HN 45 3032
