My chrysler 1999 300m keeps shutting down while driving it shows code p1684 so I got new battery and its still cutting off could it be my sensors are bad

Some times the lights will go out after the car is started and shut off about a dozen times. If not, I would take the car to an AutoZone, or other parts store that runs the codes free, if everything is ok, they may have to reset them.

no nothing to do with that

P1684 only means battery power has been lost sometime in the last 50 engine starts. If the battery has gone dead or has been disconnected, this is a normal code. Begin by testing your battery. It could be as simple as recharging or replacing the battery.

Google the question & code for your vehicle

Have to component test,no one can guess for you

Hi,
I just wanted to show you what I found on the internet regarding p1684:
"P1684 engine code

The P1684 code simply means that the battery has been disconneted within the last 50 starts."

CODE P1684 - BATTERY HAS BEEN DISCONNECTED.LOOK FOR LOOSE BATTERY CONNECTIONS. ARE BATTERY ITSELF HAS CELL PLATES SHORT INSIDE OF IT. CODE PO171 - FUEL SYSTEM LEAN. CODE PO462 - FUEL LEVEL SENSOR NUMBER 1 LOW INPUT. ALL YOUR PROBLEMS HAS TO DO WITH CODE P1684. CHECK BATTERY HAVE IT LOAD TESTED AND CHECK BATTERY CABLES FOR TIGHTNESS.TO KEEP FROM LOCKING OUT RADIO TURN IT OFF FIRST BEFORE YOU DISCONNECT NEGATIVE BATTERY CABLE.

Check,tighten & clean all battery connections & Have your battery tested.Load tested. Usually a weak, or defective battery will cause this code to come up also. While they're at it, have them test charging system. My guess is autozone will check it free or cheap, if you buy the new battery there if required. Have you noticed it turning over maybe a little slower when starting occassionally?

Code 1684 metering oil pump temperature sensor circuit malfunction.
Have you checked the alternator? It sounds like it is not charging the battery. countrycurt0
