MasterNo; computer didn't need to be reset. Whatever happened to cause the crankshaft position sensor code to get set will probably happen again. The right thing to do if and when the light comes back on is have the sensor signal monitored by a diagnostic tool. If it drops out, you have a wiring or sensor issue.
