It can locate position with match — true or false? (3,8,4)

'it can' is the definition.
The definition suggests a singular noun but the answer is not.

'position with match true or false?' is the wordplay.
I cannot really see how this works, but
'position' could be 'lie' (lie can mean to place or position) and 'lie' is present in the answer.
'match' could be 'test' (test match is a kind of match) and 'test' is located in the answer.
'or' is within the answer.
The remaining letters 'detect' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

'locate' acts as a link.
