You need a scan to find out what is causing the indicator lights to come on. There are numerous sensors and electrical components within the system that can trigger the indicator lights to come on.

Of course. The CEL shows when an error has been detected and it could be anything from engine stalling to misfiring or even go to " limp mode ". The PSM indicator light could be due to the fault as indicated by the CEL.
