The reason someone's taken them off is most likely that they broke when they had to remove them for some reason

(usually replacing wheel bearings).

New ones can be quite pricey.

It's not really a big deal to put new ones in, but you have to be really careful handling the sensors because they're quite fragile.

Google for

'mr2 abs sensor'

-- one of the first hits is a thorough guide for replacing them.

As far as I can see the parts are the same for the NA and Turbo cars

-- the part numbers do seem to match.

Just make sure you still do have the cable ends

+ connectors in the engine bay.
