P1684 means the battery was disconnected within the last 50 key starts.

I have a 2005 Chrysler 300. The engine light comes on from time to time -- sometimes it will stay on for a week or so and then go off for at most a day or two. I had the code read yesterday and the feedback was "EGR pressure flow is low." My car has about 65K miles. Is this a typical problem with this car? I was told replacing the EGR valve would fix the problem. How easy is it to replace an EGR valve on this vehicle? Once replaced, do I need to reset the computer --- if so how do I do this? If it is easy to fix, could you please provide step by step directions and show me location of the part in question that needs replaced?

P1444 Purge Flow Sensor Circuit Input Low

The evaporative emission control system checks to make sure there are no leaks in the lines that run from the gas tank to the charcoal canister and up to the engine. It also checks to make sure the gas cap is sealing correctly.
When you fill your car with gas, the vapors in the tank get forced into a canister filled with activated charcoal. Also, on a hot day as the gas heats up and vaporizes, those same vapors push into the canister where they're stored. But the charcoal can only hold so much vapor. At some point it has to be emptied. The emptying process is called "canister purge." Here's how it works.
The computer orders a canister purge by powering open a PURGE solenoid. That opens the vacuum line between the canister and the intake manifold. At the same time, it opens a VENT solenoid. That allows fresh air into the canister. So the engine is literally sucking out the gas vapors and purging the canister with fresh air. The computer has to adapt its fuel strategy to take advantage of all the extra gas vapors coming into the engine.
The computer notices the canister is empty when it detects a leaner condition (all the vapors are used up) and it resumes normal fuel delivery. Some car manufacturers then close the VENT solenoid but leave the PURGE solenoid open. That creates a vacuum throughout the entire fuel storage system. Once the correct vacuum is reached, it closed the PURGE solenoid and waits to see if the vacuum holds. If it doesn, the system passes the test. If it detects a leak, it sets a code.
In this code P1444, the computer sees a lower than expected value on the purge flow sensor. bottom line? replace the purge flow sensor.

There is a TSB for this issue: It is in "limp" mode. It is not unusual for the Sebring - Should be covered by Chrysler.
