EricTheCarGuy Explains Check Engine Codes - P0455, P0456, P0442 EVAP System Leaks

Good to see Eric doing everyday repair videos.

Hello Eric!

Bro keep Eric making more videos 👍🏽

Hello- I’m getting that P0442 code. I have bought another gas cap. When I take off in my 2010 srx cadillac like it stuggling to get air. It does it only on take off. Then smoothes out. I changed purge valve, map sensor. and when I turn heat on its smells musty. I did change the air filter & cabin filter.

Excellent!

My truck does not come with a fuel cap

Hi professor Erick thanks for this helpful information but can u tell me I'm working on 11 Mercedes c300 po455 I did smoke test I didn't see no leak but I replace gas cup and check purge valve and is good what else should I do pls help me

I refilled my w204 to full tank 2 days ago and there was a huge leak of fuel from underneath the car while refueling and this continued until gauge dropped to about 3/4 of a tank , please help

P0456 code small leak checked hoses even replaced the vapor canister and the purge valve I suspect it’s the fuel tank pressure sensor because after erasing the code it comes on after 100miles then goes away after 100miles then comes back again after 100miles and stays

Eric da Man! Didn’t know u changed ships! Good for you, you’ve been one of my favorites over the years 💪🏼

It’s a fault code problem is oil pump solenoid small leak in front right

EVAP System Leak Detected
Gross Leak/No Flow
P0456

Thank you Eric, good video
Suggestion would be to have extended the video a little bit to then show the process of testing the purge valve in the engine bay which most people have access to, as not to many people have lift to be able to take out the charcoal canister. And to do a visual inspection of the rubber tubing in the engine area as most old car the rubber gets old and hard and cracks. Thank you

It's the worst code in the world

Can this P0456 be caused by allowing the car to sit for 6-8 weeks at a time between drives?

Mil gracias por ponerlo en español 🎉🎉🎉🎉🎉🎉

Claro está debajo del auto pero deberían ponerle una protección de metal para que el evaporador no sufra daños. En que depende cada evaporador es diferente depende del fabricante. Está súper bueno el video. Aunque es difícil encontrarlo en español el vídeo.

so is this why a check engine light would come on ? including an oil leak or not ?

Thanks, still confused.
