EDIT for future reference.

Had a P0113 code which is IAT intake air temperature code. this has to do with your MAF sensor. I changed it and the code was still there. turns out that one of the wires in the harness was broken. got it welded and now the check engine light is gone.

in conclusion If you have a P0113, remove the tape and check to see if the wires are cut. If that doesnt work swap out your MAF sensor with another fellow 6th gen and see if you still get the CEL. If no code, then theres your problem!

NOTE: removing the MAF sensor is as easy as filling your gas tank. You need to use a tool that looks kind of like an allen key which you can get from your local autozone. Forgot what to tools called lol. DONT use a vicegrip because you might strip it. Its basically 2 bolts, pull it out and swap the new MAF sensor in.

 

English please..?




I don't know man... Is it not running?

I'd call another dealership.

EXACTLY. im just looking at it like uhhh wtf?!?!?!

 

Your on 6thgen right?

PM Winterfaust. He's a service manager.

Or I can... Let me know.

 

Do those even have anything to do with the trans.

iat is part of the maf
nats , isnt that theft

misfire could be because of the maf or coil pak

 

i tried to register for 6th gen org but they never approve my account!!! iono whats sup but yeah can you pm him for me? and also where does he work?

i have NO idea but basically the guys at advantage nissan told me to kick rocks, you have too many codes/mods get lost, heres a number you can call and hopefully they can help.

 

Well Ive heard of a bad maf(which the iat is part of) to throw mis fire code. Try to clean or replace it. That might solve 3 codes. Still looking up the nats and possble solutions.I came up with this for the u1000 code.
the u1000 is a can communication problem. All of the computers in your vehicle are networked together and communicate with each other on the can line. If one or more computers is not communicating you will get a can code (u1000 or u1001) There is a bulletin for this issue to clean ground connections.

 

thanks man!! they referred me to vinny ten but i know that guy is going to charge me an arm and a leg to fix all my problems... but do any of these codes have any thing to do with my transmission?

 

I Pm'd him...

I'll post when I hear something.

 

The p0726 has something to do with the trans. According to the fsm a possible cause is

Harness or connectors
(The ECM to the TCM circuit is open or shorted.)

All could go back or be related to the u1000 ground theory.


p1726 code

DTC P1726 ELECTRIC THROTTLE CONTROL SYSTEM PFP:23710
Description UCS005IU

What mods and what have you done latley?

 

well the check engine lights have been there SINCE i installed the headers like last spring?

but i just got back from autozone...... the only code that they pulled up was

P0113 IAT INTAKE AIR TEMP CIRCUIT.

i have a injen cai..... what should i do?

 

First you need to invest in your own OBD scanner:



Read the codes yourself and perhaps look them up.

The only codes you should get from the headers are the O2 sensor codes.

I started getting MAF codes when I started having problems with my SAFC; it turned out my CD changer in my glove box pulled on the harness somehow. Resecured the harness and the MAF codes are gone. You might want to visually inspect your MAF sensor to see if it was dirty; shouldn't be if you have a good filter.

If all else fails try clearing the codes and see if they come back.

 

I can't give you much help other than that you are not alone with your problems. I have had 3 previous Nissans and this Max has completely turned me off from any other Nissan ever again. Luckily I purchased the warranty otherwise I would have drove it in the ocean.

 

Vinny Ten is still around ? I heard he was doing time for ripping folks off ? I guess my sources was wrong.

 

well thx for the info guys. im going to try and swap out my MAF tomorrow because ive heard that many people think their transmission is going but it turns out to be the MAF. lets see what happens..... i still dont understand the 42819219 other codes i got if autozone obdii told me just that 1 MAF code.

yeah hes still around, he moved his shop to babylon Long island ny. lol he does charge a ridiculous amount of money but he knows his stuff and does things right.

 

maybe the headers [i believe u did the obx altima headers] melted one or more wires in the area?

 

..........

 

hmm that could be a possibility. i dont understand because i DID get a engine light after i did my headers but i thought all i needed was some o2 simulators? anyway i found a 6th gen MAF from a fellow member so i will be swapping them out saturday and well see what happens. thanks for all the input guys.

my battery DID go dead like uhh october i want to say? i have a optima yellow top though howd it die! lol no i dont have more than one nissan and i have 2 keys both for my car. nope didnt use a aftermarket key. i bought the autostart that nissan offered me.

i dont know if this means anything but my key losts is programing since im always using autostart. wtf is up with that?

 

Well if your key lost your programming that could have been the nats code the dealership pulled.

 

Is your car auto?

If you changed the tranny, that will **** of the CAN lines, which then **** off the eThrottle even more.

And will get the NATS mad as well. The may need to make the new tranny get along with YOUR ECU.

This is why Ihave no confidence in Nissan techs.

 

yes i am auto, you dont remember me?

 

Now I do, read my post for advice.

 

i say sell your car and get your self a balck or blue WRX with gold rims

 

I think the MAF is a good ave to go first. I think also the melted wired theory has some merit as well. I am not sure if there is any coating on them or heatshield action. On the subaru topic. I just picked up an 04 wrx two months ago and so far it is the best car I have owned. There are somethings I miss from the max like just cruising factor. But everytime I get in the WRX I just smile. If you like tuning or doing stuff with your car it is one of the most solid platforms with tons of help out there for them. Anyways, off the soap box.

 

ok i just swapped out my MAF sensor and went to autozone to clear my codes. theres no engine light!!! if the tranny is going bad/blown.... there would be an engine light right? just making sure. car doesnt feel weird any more. just gotta get new mounts and throw on the racingline MMI's now. thanks for all the help especially redls1

 

Damn, I wanted dibs on that bumper. Glad you found the problem. And yes, a bad MAF signal will also cause the tranny to do crazy things.

 

ahhhh crap. so I got the codes cleared at autozone, shut it off and started it and then drove off. I got home grabbed some food and head out to class.....guess what? check engine light again. Wtf!? does that mean that the maf that I just threw on is bad also? I mean the P0113 IS a MAF code. I'm debating whether or not to buy a new MAF sensor from the dealership for $225 right now.

 

I've also heard something about the pink wire on the maf harness touching the strut tower? can anyone elaborate? also cefiro said something about the wires melting? plz explain.

 

lock thread! problem solved! refer to first post!

 

Why not delete the first post, or PM a mod?

I think this thread is good to keep and not delete, therefore, why not PM a mod in order to keep the thread around, but have it locked? Good for future reference vs deleting the entire thing (i.e. deleting first post).

 

I'm assuming it was one of the O2 sensor wires. Same thing happened to me when I got my headers installed. Melted the wire within hours. Took it back and they fixed it.

 

O2 sensor wire will not cause an IAT code. My guess is that perhaps one of his MAF wires was the one to 'blame'.

 

hmmmm well my CEL is back again. WTF? when i got it cleared the guy said that i had some kinda MISFIRE code. im going to go check what codes i get tomorrow. lol but what can this misfire code mean? could it be something to do with my bad engine mounts?

i looked up the misfire codes and im guessing that i threw up a P0300 code and it means
http://www.obd-codes.com/trouble_cod...e-detected.php

could this be due to my headers and the need for a o2 simulator?

 

Misfire = coil/plug/injector.

 

new developments in my never ending horror story. new code is P1273. spoke to some ppl and they said I have to reprogram the ecu? info?
