Question

How long for the P0456 code take to clear after repair on my 2011 Chrysler 200 4 Cyl? I got the engine code P0456 code after the gas cap replacement.

Answer 1

Hi there,

This code can take quite a while to go away on it's own. The car has to run the drive cycles at least twice before the code will clear on it's own. You should have the code cleared, then drive the car to see if it comes back on. It would be the quickest way to determine if the gas cap was actually the problem.
