I have the older Actron ScanTool style that uses different "cards" and it is a self contained hand held. I have the OBD-II card that plugs into the unit and then I can read OBD-II codes, as well as some of the sensor output. However, as I mentioned, it does not display ALL of the sensor outputs, which is the weak point. It does display key info like:

RPM
Short term fuel trim
Long term fuel trim
Oxygen sensor (both banks) voltage and %
ECT tempeature
ACT temperature
And several other ones that I cannot recall off the top of my head, like duty cycles for EGR, etc.

It also does inform if all of the readiness monitors have been completed, and if not, it displays which ones have not been completed at that time.
