i have a p0455 on a 05 kia sedona. my scanner show tank pressure show -15 in both key on engine off and running. bad pressure switch? also when I smoke test with key on egine off i get smoke from the top of the tank, but its not the fuel pump gasket. any advice would be great

@jayvian327 Жыл бұрын

I am having issues with this p0455, I tried just about everything. Would you mind emphasizing at 7:08 your back probing the dark green wire. But you switch the test light from negative to positive and that is suppose to test the command to the purge valve? Is this correct? I was a bit confused about swapping with tester from neg to positive on that same dark green wire, without short circuiting anything. I just would like to confirm that this is ok to my understanding.

@Mdavied2023 5 ай бұрын

yes he is right. he connected the connector , key on , command the computer , which means there is 12v up to the solenoid. which means complete circuit (the 12v goes through 10A fuse to orange wire to the solenoid going out to dark green wire to the chases ground

My mom has that same exact code on a 2017 Kia soul and it has me frustrated,I already replaced fuel cap with OEM cap, purge valve (OEM) fuel tank pressure sensor OEM as well and the code keeps coming back, I'm doing a smoke test tomorrow any pointers on where to connect?I was thinking using the vent line under the hood that goes to the tank or back, should I pinch of the line at the end before the canister or should I not? I'm not a mechanic I just like to try and fix things myself.

Honey, We really like your videos, very clear and patient. I was wondering if you would be interested in taking a video of our inflatable paint booth. Free for you to use our upgraded inflatable spray tent, even indoors, the double-layer EPA-certified filter cotton and the elephant nose filter system can achieve a good filtering effect. Please reply me if you are interested. thanks

@AlchemistAugen Жыл бұрын

Visual inspection of hoses, connections, valves. I have seen a pseudo smoke text using vape smoke, interesting but I don't vape, and a handful of people spraying a soapy water mixture around pertinent areas...seeing bubbling is indicative of a leak.

I'm so confused now. I have P0300 P0455 & P0456. Seems the causes overlap one another. I've watched videos for each & just more confused. 69-yr old trying to make sure the maintenance shop doesn't rob me blind for something the car doesn't need. But your vid was good, clear except I have 3 codes.

I just got a full tune up not even a week ago.. then suddenly the check engine light is on? I bought a scanner awhile ago so I used it and got the large evap system leak code,,,, I don’t smell gas inside and only outside for like 10 seconds… I do not overfill it. I don’t even drive it much actualy. Couple times a week and not far.. but this wasn’t and issue a week ago.. so could it just be the cap???

I know that he said simple check, but at the end he leaves this video without an actual fix. It's obvious that p0455 can be any of the things that Hector mentioned, but it also shows that it can be another part of the fuel system. It could be the evap canister, it can be a hard line, it could be a soft line aka rubber hose. It also could be a simple gas cap or it could also be a bad tank. You should also check all your fuses and more possibilities.

@freedomthinker3041 4 ай бұрын

@@CUSOCOOL I know people can say it is simple and for the most it is. I say it is because I did everything an ASE shop would do and did...perhaps even more because if the problem persist that's after I did all same work a shop did. I don't like taking it to shops because when I know there is a problem still, I pay and the and the shop tells me that there isn't anything wrong or that it must have been that I didn't clear the code correctly that must have been the problem...that's an insult to my intelligence. On top of that the shop has the nerve to tell bring it back so they could charge me more if the problem persist...I say no thanks. By the way I actually found the problem and permanently fixed it something that a real professional would have and should have done in the first place. So as simple as it may seem just to do a check. I would argue checking and fixing are two different things.

Start withe basics Friend #1 check your fuel cap..make sure it sealed tight. #2 check you throttle body connection...make sure all connections are connected securely #3 clean your throttle body with throttle body cleaner #4 check the wiring to your o2 sensor(s) and/or possibly inspect & clean the sensor with the throttle body cleaner & wire brush. #5 clear check engine codes Hopefully this basic maintenance can help you with your codes. They seem to point at your throttle body, evap & 1 of your O2 sensors

Turn to Jesus people he died for your sins, Repent of what the New Testament describes as sin. Believe the gospel obey the teachings of Jesus documented in Matthew, Mark, Luke, and John. Jesus is the only way to be saved, be baptized if you have faith in Jesus then you will live life with him as your example. If you need prayer i'll pray for you. If you want to keep contact with a brother in Christ i’ll keep contact with you. The love of God is beyond our understanding. God bless.
