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!
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 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.
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!!
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.
@@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
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.
I repaired P0442 replacing a seal inside gas tank (doesn't have part number). That seal is Viton material, It was elaborate in a lathe. In that way I avoided to buy a new gas tank

Ugh i need help i have this code on my 2009 chevy cobalt, i replaced the gas cap but i think its something loose because i still get “check gas cap” message from the car when i fill it sometimes and my check engine light is still on after 1 1/2 weeks of driving , birthday Nov 7 so emissions coming up, do i just need to take it to a shop im trying to avoid paying over for something that could be so simple 🙄
2016 Land Rover discovery sport. I replaced the gas cap. Getting p0442 and p0456 codes that when cleared come back on. Any ideas would truest be appreciated.

I have a 2014 Mustang and cleaned the filler intake valve and replaced the canister purge valve... Still came up again after another 100 miles... Probably the whole fuel neck filler.... Sheesh its $140 bucks fml ..
Hello, have you checked if there's a leak in the fuel vapor hose that leads from the fuel tank to the intake? kindly inspect also if you have a bad fuel cap or a loose gas cap.
Bro u have a mustang and complaining about $140 💀 I took my 2002 Toyota Camry to a repair shop to replace spark plugs and they tried to upsell me to buy other stuff and the final price was $1000+ then I just went to my uncle and his friend did it for $50

I have a P0442, P0137, P2270. I have change and the gas cap to a new one cause it lost the seal, I also change purge valve, and the oxygen sensor two but it still comes out on my Chevrolet cobalt 2010 2.2L. I changed the purge valve more than once and the sensor as well.
Hi Joseph, as you are receiving more than one error code, we suggest getting your vehicle visually checked by your local mechanic for further diagnosis. Thanks for watching!
I have this on my 2004 hyundai santa fe. How hard is it to replace the fuel neck filler with out taking it to a shop. When I pour gas in it leaks out so I'm assuming that's the reason for the code. It doesn't come on right away tho. And weirdest thing, the code stays on but all monitors are ready, the evap will go green
1996 Hyundai Elantra Same code, been searching for the issue and can’t find it chanced Canister, Vent Valve, Purge Valve, OEM everything & gas cap as well Still same issue.
Hi Carlos please check if there's a leak in the fuel vapor hose that leads from the fuel tank to the intake. We also suggest checking the condition of the fuel tank pressure sensor.
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
I have a 2006 Chevy Impala SS. I followed the steps in your video and I still have the p0442 DTC. I've also replaced the evap vent valve but code is still there. Any other tips?

must be the gas cap, i lost the cap on my superduty and engine light came on, after a month, i was using an older modal gas cap, just odered new one from the dealer today
Please help me i have engine code P044c and P044C(11) i cant find what exactly it is its something with the EGR (exhaust gas recirculation valve position sensor C - circuit is that mean the EGR valve itself or is a sensor somewhere i have Infiniti Q30 and its a Mercedes engine i clean all the valves and both egrs and the manifold it was dirt in there but after 2 - 3 months the error show again if someone have some more info from the basic in google for that i will be infinity thankful
@@nondainc im not mechanic . how dies car sense gas leak anyway if gas cap closed and if under car how does it know esp while driving aur is moving under car
Hi Leonardo, make sure that the gas cap is in proper fitment/condition. Check if there are cracks in the fuel tank/ or charcoal canister and inspect the EVAP lines for damage.
My mechanic solved it by disassembling the gas tank, he changed a viton seal that is submerged in the tank. I ordered this stamp to be prepared according to the model.
Hi guys, so I have NONDA scanner for my 2010 NISSAN MAXIMA I also got P0442 error code I got new cap from amazon cleaned my fuel cap hole, cap ext my after a few days I got engine light on again so I got another new gas cap cleaned everything and put the second new cap but again after 2-3 days I got engine light on both caps that I purchased aftermarket parts so do you guys think I have buy ORIGINAL gas cap for this error code ? OEM part is $70-$80 but aftermarket was $15-$25 I was wonder if this cap is really sensitive for engine light or should I go to next step and replace Purge Valve ? Also should I get OEM Purge Valve part for this error code since it's coming back after 2 fuel cap aftermarket replacement. PLEASE RESPOND ME :)
@@shred9395 Thanks for the hands up but after I made this comment I hit under my car to pot hole here in Queens NY and my car totaled so insurance company paid my car and I got 2021 Camry SE zero issue since I got it but now looking for infinity Q50 or Q60 :)
Hi Ruso, loose fuel tank filler cap is the most common cause that triggers this code. Malfunction is detected when evaporative control system has a leak and doesn't operate properly. You may follow the tips/suggestions provided in our uploaded video (How to fix P0442) and see if the issue will still persist.

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