Question

I have a 2007 Dodge Grand Caravan 3.8L with 90,000 miles. It has a p0456 code. What does it need.?

Answer 1

The P0456 code indicates a leak on the Evaporative (EVAP) system. A loose or damaged fuel cap is one of the most common causes of a leak on the EVAP system. I suggest starting by tightening the fuel cap and if necessary replacing the cap. If the problem persists, further testing will be required to find the lake. Here is a link to the cod page for more information about the code:

Answer 2

There is no specific part to replace with this code.This is an evap leak code, what should be done is a smoke test on the evap system to locate the leak and then make the repair from there.
