2012 Ram 1500 Gas Cap Loose Fix P0456 P0457 Evap Codes #checkenginelight

@HowIFixedIt
Check engine light on with PCM codes P0457 loose fuel cap & P0456 small EVAP leak. Dodge Ram pickup “gas cap” warning light came on but the gas cap is fine. Tried tightening it down (even though it didn’t need it) and the light never went off. Could there be another issue or is this a common computer error? No, you have an EVAP leak and the self-test is reading it. There is no such thing as a “common computer error” as the ECU can only do what it is programmed to do, and it is programmed to run system quality checks. But the gas cap is not the only thing capable of leaking, just the most common. The professional troubleshoot generally involves “smoking” the system (injecting smoke to detect any leaks) and can be a real pain at times. Rams are known to be rust-prone, and the Chrysler filler necks to the fuel tank are often perforated with corrosion breaches that won’t pass the self-test. Failed leak detection pump and charcoal canister was the fix. Replacing charcoal canister and leak detection pump on a Ram 1500. #howifixedit #automotiverepair #preventivemaintenance #shortfeed #shortvideos #checkenginelight #evapleak #gas #charcoalcanister #leakdetection #leakdetectionpump

Have the same code. I can smell fuel after driving as if it's leaking gas out. I will Def take a look at this. Thanks for the short and sweet video. You rock!!

Wondering if it’s the pump for me or the canister? Took off purge and blew thought it and I couldn’t do that should be good. But after using Alfa odb I see I have a small and large leak and after doing purge, the 441 code.

Could you help identify a possible issue with my gas pump? When I’m pumping gas, it keeps stopping as though the tank is full, even though it’s not. It cuts off every $1 or $2 worth of fuel. You can only image how long this takes to fill up, lol. I don’t have any warning lights or indicators on the dash showing a problem. The vehicle is a 2018 Dodge Ram.

Just replaced my fuel pump, seals are all good but check engine came on said gas cap is loose and check evap systems

Mine is misreading but the engine smells like dried gas or something and I replaced the gas cap and it’s not loose
