P1684 code

Post by mickeytopher » Thu Jun 05, 2014 10:00 am

My wife's 02 SOHC has a constant P1684 code. The battery is not even a year old, and the connections are pretty good. Any one have an idea what might be going on?

From what I recall, it's one that you either have to "wait out the 50 starts" or it's just always there. I had it intermittently on my current car and my first Neon it was always on.

Check the battery cable to the PDC. That code can be set by an intermittent bad/loose connection. Other than that, make sure that the battery connections are clean and tight.

If it still doesn't clear, it isn't an issue, it will not affect the way the engine runs. Some cars just never get rid of it.

It is the equivalent of error code 12 on the OBD I cars. Every 1980's car I owned always had 12 pop up when the codes were ran. If you had 12 and 55, you knew things were usually good, as far as the PCM was concerned.


I always get P1684, P1686 - from having a SKIM pcm in a non SKIM car, and P1289 - from that SKIM PCM being an R/T pcm in a non R/T car.

Some cars have the battery code perpetually, some cars don't have it at all. My R/T does'nt have it coming up at all. It can't hurt to double check all the positive and ground connections.
