Hello all forum users.
My name is Radek and I write from Polish.
I'm the owner of the Chrysler Sebring 2002, engine capacity to 2.0.

I have a few issues that I want to discuss with you.

Shows me error code P1684 and P0204, the car is mounted installation of LPG.
I noticed that after erasing a fault code for some time no check engine light was on, the time when the car was a low fuel level. After refueling, once the light goes out, and sometimes lights up.
What could be causing this?

 

P0204: OBDII Code P0204 - Injector Circuit Malfunction Cylinder 4 | HelpForCars.net (Bad fuel injector circuit for cylinder #4)

P1684: P1684 Chrysler Battery Power To Module Disconnected OBDII Engine Light Trouble Code | Engine-Codes.com (nothing to worry about)

Sorry, can't help with the refueling question. They don't sell LPG fueled cars over here. Nor did they sell Sebrings with 2.0L engines over here. Maybe a European reader might chime in.

 

Thank you for answering my questions.
I am calm about the error P1684 , the rest of the answers are still looking for
