Consonants that may occur in the coda are /l/, /r/, and /s/. From a phonetic point of view, nasal consonants also occur. From a phonological perspective, nasal consonants only appear in the coda if the phonetically prenasalized consonants are analyzed (following do Couto & Sousa 2006) as sequences of one nasal and one other consonant. In my opinion, they are to be analyzed as monophonemic (cf. Lang 1999 and 2007).
