I'd had a P0456 code, and sometimes a P055 code on my 2013 Jeep JK
Wrangler for an embarrassingly long time... like several months, on and off. For a while, I just ignored it.
I had inspected all the evap hoses, smoke tested it, replaced
the gas cap, and more. It ran ok.
Then I realized I needed to pass emissions, like uhh, now.
Here's what I did. I replaced the vapor leak detection pump.
It is a small part located on the rear underneath the vehicle. It's really
easy to change. It took me about 15 minutes total, and all I needed was a
flathead screwdriver.
For a few days after clearing the code, I
drove my Jeep about 100 miles on the freeway and surface streets to make sure
the check engine light didn't come back on, like it did every other time I
thought I'd fixed something.
It stayed off (yay!), so I went to the emissions testing
facility, and passed!
While every vehicle is different, this is what worked for
me. It may not fix your P0456 code, but the part was pretty cheap and very
simple to change. It's worth a try if you're not sure exactually what's causing
your Jeep to tell you that you have an evap leak.
Check out my video that shows
you how to swap it out!
Here's a link to the part I used:
