Question

On my 2002 Jeep Liberty 3.7L, where is this valve located? I have the code P0455

Answer 1

Hi there

This code is for a large evap emissions leak. This doesn't point to a specific valve, but could be simply a loose gas cap. If it's any valve it could be the vent control valve mounted on the charcoal canister. Here is some more info on the code and possible causes.
