code help

[jfp3205]

Good Morning,
I just bought a ford Rotunda superstar 11 code reader and I am trying to locate any information on how what tests I can do and what the codes are. I have two codes that keep coming up and I an not sure what they are.
When I turn the key to on, I get the code 23 and when I start the truck, I get the code 50
Any help on this?
Thanks

what trans? must be auto, a '92 has no ECU to throw codes. those codes must be from the trans control unit

23 Throttle sensor out of range or throttle set too high - TPS

50 False code.

Does anyone know how to erease these codes with the super star ll rotunda scan tool? This vehicle has the eod4 and the overdrive light on the end of the control stalk
Thanks
