Question

I have a 2003 Chrysler Town & Country 3.3L with codes P0442, P0455, and P0456, what is the problem?

Answer 1

HI there,

All of these codes indicate there is a leak in the evap system. The best method for diagnosing this is to have a smoke test performed. This will locate the leak, then you can do the repair yourself to save some money.
