Question about 1994 Ford Crown Victoria
At first I had a 172 code on O2 sensor, so I changed it. I was losing power going uphill and it runs/idles bad until it gets warmed up and then it runs better.

Paul what is VPWR not familiar with that term. I will leave a tip tomorrow after I have had a chance to check what you told me.
Vehicle power supply to one of the transmission solenoids. I researched this code through ny shop computer and it is very vague. I have never experienced this code in all my years repairing cars. You may need a breakout box to find this problem as the ECM on these older vehicles are like dinosaurs. Hope this helps

122 is
TP low (possibly grounded or open circuit) - TPS
that suggested it's not really the sensor itself is bad, but a wiring problem!
gotta trace and make sure the ground circuit and or wiring to that sensor is not broken
as for the other 3 digit code, no idea as well. reset the ecu/ecm and read the flashes again

Hello
When the service engine
soon light (Also called the check engine light) is turned on this is
to alert you to the fact that Powertrain Control Module (computer)
has detected a failure somewhere in the systems it controls you may
not feel any difference in the way the engine runs, this can be the
transmission or the engine or emission system, there are fault codes
set in the modules memory for these faults. What needs to happen now
is to have the powertrain control module scanned with a special tool
called an OBD2 electronic engine control scanner or a OBD2 code
reader. Once the code(s) are read then you must perform the
diagnostics for each code and make the appropriate repairs based on
the findings of the diagnosis that was performed, this is called
doing "Pinpoint" testing.
