According to the 2000 Neon service manual (codes also listed online, search
google)

P1684- "The battery has been disconnected within the last 50 starts." No
real significance. Dealer could have disconnected the battery when there
were in there, sometimes it goes on by itself. Don't worry about it.

P071 - My manual doesn't show this code as existing. Did you get it right?
Here's some possible similar codes that will light up the check engine
light:

P0117: ECT Sensor voltage to low (engine coolant tempereature sensor input
below minimum accepted value.
P0171: Lean air / fuel mxture has been indicated by an abnormally rich
correction factor.


P0711 lists as "Trans Temp sensor voltage too low". but shouldn't illuminate
the MIL lamp. I don't know if this even applies given the 3 speed in the
Neon.

I remember thinking it was neat decrypting a blinking light to tell me what
ailed my '89 Reliant, and '96 Neon, but I was blown away when it listed the
codes on the odo in the '00. I was expecting it to blink the light, not just
tell me the code. The first time I was successful I wasn't able to write
down the codes, I was laughing too hard.
