Mike56 Posted August 24, 2023 Report Share Posted August 24, 2023 I have been getting the P0456 code after erasing it a few times. It has been running rough upon acceleration. I cleaned the fuel inlet area, Filled a few tanks with high octane fuel and used a few cans of Sea Foam. Still chugging upon acceleration. My next course is the canister purge valve. I've seen on this group that the purge valve is location near the rear axle, however not true. It looks like it's under the air filter box. Any suggestions on a fix? 2020 Ford Edge SEL 2.0 Turbo Quote Link to comment Share on other sites More sharing options...
lildisco Posted August 26, 2023 Report Share Posted August 26, 2023 I thought that purge valve is under the hood on the drivers side of the engine. Is there a canister purge valve in a different location? Our 2016 2.0L purge valve was on the driver's side of the engine. Was ~$150 part.

When I replaced my evap purge valve on my 2.7L the service manager mentioned that the code is most often resolved with the replacement of this valve, but a very limited number have needed to replace the canister vent vale near the rear axle. The P0456 points to the evap purge valve typically mounted close to or on top of the engine, as is the case with my 2.7L, but could also be the canister vent valve or poor sealing gas cap. How's the coolant level - losing any coolant? Maybe @Haz can help with more info. Edited August 26, 2023 by 1004ron Quote Link to comment Share on other sites More sharing options...
