2000 Dodge Neon code P1684 and P0171
My check enginle light just came on about a hour ago. I turn the key on and off twice. And these two numbers came up on the dashboard.
P1684 and P0171 Can anybody help by telling me with the two numbers mean for I don't have the book to show what these numbers mean.. Thank you |
Can't find the first one in the 03-05 manuals, but have the other one.

i couldnt find much on the P1684 code
but id did find on the internet that this is cause by the PCM loosing power at some point. Is your car acting funny at any time like loosing electrical power, misfiring, anything? Only thing i hate about new cars. Whatever happend to the good old style engines with carbs and distributors lol.. now everything has to have a *brain* to run. |
Haha, even the carbs can be a PITA though.
|
lol agreed
|
what code P 1684 means ...
P 1684 just means that you have disconnected the battery recently ...it wont have any effect on the way the car runs .
