How to Fix P0442 Engine Code in 3 Minutes [2 DIY Methods / Only $4.67]

[@nondainc]

Hi, I'm Steve, nonda's lead mechanic engineer. Feel free to leave your comments here if you have any mechanic questions, I will be glad to help you out!

[@murat7006]

Hey Steve, I have the same error code with a 2017 bmw 430xi gran coupe. I have a deleted resornator and muffler. Would that also cause an issue ?

[@mobobb3555]

Hi Steve My friend has a 2005 Ford Explorer with a 4.0 Liter V - 6 motor installed in it. Code read out says P0302 and P0442. Her mechanic is telling me that he believes that the problem is that the number two cylinder intake valve is stuck open for some reason. He says that his next step is to remove the valve cover to examine / ascertain the problem - cause for repair. What do you think about this situation ?

[@JG-ef2cn]

Is this a serious pcm engine code or can I still drive my car?? Thanks

[@cornfusedatbest6693]

@@JG-ef2cn IMO, no, Unless the smell of gas and the check engine light bothers you. Most of the time it's the seal on the gas cap. If you live in a state where emissions are an issue, your not going to get your registration updated, therefore, clean everything first like Steve said and go from there. Hope this helps you out. We're all in this together. Good luck.

Muchas gracias por este excelente trabajo me sirvió de mucho.😂

[@morebeer7673]

Don't throw money at the problem, because there are a dozen components that can trigger this code. Before you piss your money away on anything new that isn't broken, try cleaning the gas cap as described. If that doesn'ty work bring it to a shop and have them properly diagnose the exact cause so you only have to pay for that one thing.

[@dennismcconville462]

What if you don’t have a gas cap? It’s just a flap.

Gas cap is majority culprit. The canister will get damage if you submerge it underwater

[@kitjasabsgabs1830]

Not saying this video is BS but after 30 years of doing this ive had many reasons why evap is throwing lights. From filling with gas while running, topping off, faulty componets, gas cap seal etc.

[@ReisePiece]

Can it happen from the car sitting for a year?

[@LandonsBuildz]

@@ReisePieceanything can happen when the car sits. Seals rot out, plastic degrades and many other things can go wrong. Gas also goes bad wich could cause running issues

I replaced gas cap 3 times and l bought a new purge valve and when I went to install it l noticed one tube goes to carborator and one hose goes down to engine exhaust where l found hose melted ou of shape now l did not know this till l started to look for a solution . Now l will by a new tubing for purge valve and reconnect and see what happens, will let you know know! Also check purge valve and tubing!!

I have a 03 mustang gt and I'm assuming it's my exhaust leak from the old stock headers. Could this be a reason for the code?

[@OFFICIALEMG_]

Yeah I have a 07 mustang and have same code. Changed gas cap still throwing code but I looked at my headers and both headers & cats look so rusted and just worn out. Wondering if that could be the culprit. Car is in very nice condition engine looks good it’s literally just them headers and cats that look bad and I get an exhaust rattle too here and there. Sometimes it happens sometimes it doesn’t
