CEL couple of sensors

[muthiahmerchant]

Took it to a mechanic for a CEL diagnosis, not sure if they do anything more than hooking up the scan tool anyways, he came back with replace knock sensor, camshaft sensor and crankshaft sensor. I replace the camshaft and knocksensor by myself and reset the CEL, Now no more CEL. Should i replace the crankshaft sensor as well or return it. its about $90.

I'd probably wait a couple days to make sure the code doesn't come back.
