Review on Dorman 911-410 Vapor Canister Purge Valve - Ideal for Select Models by David Bar

. My 2018 Chrsyler Pacifica MPV had a check engine light on. When I read the codes with my OBD reader it showed P-0456 which is a minor emissions leak. The most common cause is a loose gas cap (which this model doesn't have), and the second most likely cause is a bad vent valve. I decided that for $28 I would try to replace it myself before taking the van to the shop. The part is under the engine cover so you will need to remove two star screws to remove it and then disconnect two hoses and an electrical wire from the valve itself. The new one connected with no problems. I had to drive for a few days before the computer checked that the leak was gone and the check engine light went out. This part was a simple cheap repair.
