Faulty fence — it I'd replaced (9)

Ross

I believe the answer is:

deficient

'faulty' is the definition.
(thesaurus)

'fence it i'd replaced' is the wordplay.
'replaced' indicates anagramming the letters.
'fence'+'it'+'id'='fenceitid'
'fenceitid' with letters rearranged gives 'DEFICIENT'.

(Other definitions for deficient that I've seen before include "less than complete" , "Inadequate" , "Lacking" .)

I've seen this clue in The Times.
