I have not had a CEL come on in about a year but this morning, the first real cold start up of the fall season and the CEL has appeared. I ahve to check the code or codes after lunch but any idea why the first cold start and know this.

ps, car has been hesitating a bit lately of the line.

 

1. Check codes
2. Search the org for possible solution
3. If no luck, start a thread and ask for help
4. Profit.

And please be more specific with your thread title..per the forum rules.

 

yah man, i think i see a hundred goddamn threads a week about frickin, " o", i got a cell. well, get the fsm and look it up or look at pmohr's sig, sheesh

 

When are these nooberts gonna learn to




Don't start a new thread for this junk, search!!!!!

 

WOW, thought u non noobs liked to help. anyway, got ks code of course and a p0440 evap, the only problem i have had in the past CEL wise, it used to happen once a month but know after almost a year again, that could be hard to figure out i would think on a 12 year old car right?? im in mass so no six is not a option any more, sticker needed in 2 months

 

As I hear always here , check/fix all the CEL issues other than the KS one...then reset the light and see...if it comes back,check/fix again...the last thing to fix is the KS

 

If it makes you feel any better, when i bought my maxima two and a half years ago, the next week I had the joys of a CEL pop up. I got it checked, and it's been on since. Mechanics always clear it, but it keeps coming back. My code is P0125, a phantom code that isn't anything to worry about. Unless another code comes up, then i'll never know. As for mine, she's always run great even with the CEL for over two years.

 

except you wont pass inspection with a c/e engine light on. unless the tech is cool and gives you a break, which could lose him his license.

 

Agreed. Fix your evap problem first, then go from there.

 

ya, but your assuming hes got inspection. thanks to jesse ventura, minnesota doesn't have inspections so i can run super illegally

 

ah, but you live in minnesota. dont you guys get like 2 feet or more of snow and cold as shiz winters??? ill take pa thanks!!! and he stated hes got an inspection due in 2 months. READ NOOB, READ!!!

 

You can always tell when maxride41 is pissed with someone, the huge bold red letters come out to play...lol.

 

So, you don't think that P0125 is important, and you live in a COLD place!

P0125
ECT Sensor




edit: and ... as mentioned SO many times before, the KS will not (NOT) trip the CEL

 

Dude. chill out. Lay off the caffeine.

 

dont drink coffee, noobs just annoy me!!!!

 

update, gas cap if fine and holds plenty of pressure. starting to get worried, MPG down a ton and every so often when I give the car gas off the line its hesitates for a second or 2. Whats going on.

 

I had the same error code and I live in the Mass too. I know how inspections are a pain in da ***. I had the CEL light come on when i installed a cold air intake. Went to autozone and they read the codes. Came back the Ks and EVAP. So I took my car to the dealer jus for kicks cuz i wanted to really check the car. They told me KS and the 02 sensor. They changed the sensor and reset the computer. No problems ever since.

Honestly i think if i had changed the KS then nothing would have been worng. Most people who seem to have that problem with the evap seem to have the KS problem too. Coincidence??? maybe not. Either way..there are 2 EVAPs to worry about...one top of the engine intake and another at rear of the car under near the gas tank. Prolly jus need to change the 02 sensor. Its too freakin hard to change the KS but u can buy one off ebay for 25 bucks.

Honestly if the car is hesitating upon hard throttle...its the KS and thats an even bigger pain in the *** to change. Im still tryin to change mine hehe

 

Wow your guys AutoZones check the codes still? Mine pretty much tell me to fk off when I asked last year. -_-

 

It's not that hard to change, and it really doesn't have much affect on performance. I am not hijacking this thread and turning it into a KS thread .... there are already a TON of them on here -

Also tips on changing the KS - no need to remove the UIM, just get a girl or kid with small hands. Plus ... it saves your hands from getting cut up too. heheheh

 

So other than the gas cap witch is fine and the KS witch i might change this week, i know its not hard, what else is the p0440 code possibly popping up for, most likely.

 

so how did it go from evap to o2 ??

 

cmon now.......

Da bolt on my KS is ridiculously tight!!! Tonight I am gonna buy some liquid wrench and lube the bolt and see if that helps hehe.

As far as the 02 sensor, the dealer performed the evap pressure test and said i needed to change the 02 sensor. I changed it and never had any problems afterwards.

 

Witch O2??

 

THe 02 sensor under the car near the cat converter. If u can get under the car then its pretty straightforward using the Haynes manual. I didnt do it myself cuz it was already at the dealer's at the time and i needed to have other work completed as well.

 

i just regisetered. i have a 99 maxima i recently got. i want to know why at the bottom of the page it says i cant make new threads and just post replys??? i have a question i wanna make my own thread

 

15 post rule. Helps keep spammers and scammers away. 9 or 10 more useful posts, and you can start your own thread. However, I can probably guarantee that if you use the free search, your question/topic has been covered before.

 

guess what, woke up this morning started her up, bang no CEL, why does my car play tricks on me??

 

It doesn't like you.

 

Dude, welcome to the frigging club. I lived with an on/off CEL for 8+ months. It sucked.

 

I too have an on/off CEL for O2 sensor voltage (seems to turn on when I push the car too hard lol).

 

Ok ... I'll pipe in too ...

My CEL for the past year has been an On / Off endevour. lol Oxy sensor as well. I just quit replacing them ... and oddly enough, it goes away (for a while - several weeks at a time) but then it comes back. I've told myself if I ever sell my Maxima, I'm gonna have to place an ad hit and miss (gotta make sure the CEL is off) LOL

 

yup, mines on/off every couple months, hope it stays off from now til inspection time but knowing my luck it will come on when I pull up to the shop.

 

Bite the bullet and let the dealer handle it....I had an 02 sensor problem CEL...took it to the dealer and no problems ever since...200 bucks tho. But how do u put a pricetag on piece of mind

 

Code: P0440 | Description: EVAP (Small Leak)





on again ^^ Really dont want to bite the bullet last chance inspection due at the end of the month. what to do, really dont want the stealership.
