I just had a look at at data sheet for that transistor, it has an internal diode across the collector/emitter so that reading for collector/emitter sounds like it could be normal, check again on diode check.. you should see about 0.6v one way and infinity when the leads are reversed.

If you get anywhere near zero reading on any transistor on any two of its three pins its fried!!

If in doubt replace i always say.. As i said before multimeter reading can't always be trusted!
