Getting codes P0452 saying the switch is “low”
P2400 Evap circuit open
P2403 evap Open
P2402 Evap leak detection pump high

any thoughts ? Possible fixes

 

What car, what year, what mileage, what symptoms? We do not know your car.

 

06 Chrysler Crossfire convertible limited
118,000 miles ..
symptoms .. just it killing my gas mileage and gas smell here n there

 

The first thing I would do is inspect all of the EVAP system hoses and fuel hoses under the car.

 

I had a gas smell in my 2006 base roadster. The end of my fuel pump where the electrical connectors are was weeping gas, no drips just damp.
Here's the post I did when I replaced mine. If you go through the pictures, you'll see one that shows the location of all of the components, including the Evap Cannister.

Hopefully this will be helpful.

 

I do not think the evap canisters are any longer available.
