P1682 code

This morning I got to work and my check gauges light was on in zj. The battery gauge was zero!! But she was running like a champ. Leaving work it did not come back on and there was no issue nor when I stopped at the store. Was just wondering if the -8 temperature outside could have tripped the check gauges light?

 

When was the last time the alternator was replaced?
The next time it acts up, if you can stop and put a multimeter on the battery and check the voltage. It should be about 13.8-14.3 volts.
Then try tapping on the alternator case and see if the voltage comes back up.
From reading online it likely needs an alternator.

 

Swing by the local Advance/Autozone for free battery+alternator test. Make a better decision after getting some analysis. Cold temps can give you a sign/clue about your battery condition and have an affect on batteries especially ones with a few years.

 

Bad battery!! Had the guy at Napa test it. Jus had it tested this fall and it was fine...However its cold as shit round here these days. Thank ya for your input here guys.
