2001 caravan ;Anyone know how to reset error P1684 apparently doubles(?) as battery disconnected during last 50 starts? Replacing sensor did nothing to help.
Thanks.

 

It's one of those nuisance informational codes that pops up for most of us. Don't waste your money, or at least any more of it chasing it down unless you have an associated issue. I've seen it several times but ignore it. Many can say the same.
