Hey guys been searching and working for weeks and still stumped,so it's time to post my own...here goes. My 03 max dies after starting.initially the problem started when the car stalled on my wife.when I went to retrieve the car it started and moved fine until it shifted into second,then the whole car shuts off.after restarting the trans is stuck in 5th.i turned it off and restarted then it drove in first on the trailer.got it home then it didn't even want to start( had to push into the drive way) and here I sit for two weeks now trying to fix it.i am using a friends scanner that is pro grade.its called a autel scanner. Anyways it comes up with cam position bank 1.so buy the sensor and were good rite...nope gone through three and still same code and symptom...although the longer the car sits without trying to start the longer it runs ,if I start it repeatedly it starts and dies but let it sit for a day and it'll run close to a minute.....any help would be much appreciated

 

If you didn't use an oem sensor, I would try that first.

 

Don't know if it's factory but took one out of my xterra (that does not have cam position code) and no action even used the x to test my bought and used sensors and that won't throw a code with the ones that the max says are bad......c y I'm stumped.....tested continuity from cam wires to ecu today and they were good...couldn't find the yellow wire from the clip to the ecu but it gets 5volts when cranking.....stumped for the day

 

Bump for some new ideas...changed crank position both cam positions tested continuity ,changed fuel pump.....should I pull the valve cover to c if the cam is even in there...lol����

 

Did the code stay off after replacing the sensor? I'm curious if that code was a coincidence or being thrown incorrectly.

 

No matter what I do the code pops after starting..... really need some help here guys

 

Bump

 

This could be one of those weird MAF problems. Borrow the MAF sensor from your Xterra and try it.

 

Yup tried that one also.....I have a crashed maxima so I have double parts to try there and my x has a extra complete motor in the back so double parts there as well so that's a total of 4 Mafs,4 crank position sensors,4 of each bank cam position plus 2 brand new .....and still same symptoms no matter what I try.....thanks for the guess though

 

Maybe ECU is ****ed

Man, one of these situations where datascan 2 would really pay off

 

Could also be your IVT solenoids are all blocked up they have very narrow passage way for your engine oil to move through they do not have a specific error code that points directly at them but they will trigger P0021 (bank 2 cam sensor or P0011 which is the bank 1 cam sensor) the IVT solenoids are located on the top part of the passenger side of the engine and are very easy to remove and clean out with some throttle body spray cleaner. They have just three bolts all very easy to get at. IVT = Intake Variable Timing solenoid, try cleaning them out to see if they are causing your stalling issue.

 

Thanx so much for another idea...will report after this is done

 

I wanted to try the other ecu from my crashed max but it won't run it couse the I mobilizer thing and the key not matching....I think my scanner can recode it it but it's smarter than me,I don't know how to use all the features...it's a touch screen autel it's was like $5k

 

I don't know if it makes a difference but in your sig your car is the older body style....on my jam it says 03 but it's the newer body😐

 

Mine is not a older body style at all it is a SE Titanium Edition ... but more importantly it would make no difference the engine is the same 3.5 as what you have, I was simply suggesting to you to check and clean your IVT solenoids as they can cause your cam sensor codes to go off making you think you need to replace the cam sensor when that was not the issue

 

Well just cleaned those v-tec things out and changed the maf .....no difference...it sounds as if it is running out of fuel...would a low fuel pressure issue make sense? Still throwing cam position bank 1...keep um coming guys

 

Okay, I've seen this for a couple days. Thought about it. A:Now because you say your car is an 03 its not... its a 2004 if its the uglier body style.
B: the engine control is the exact same. So what I am going to suggest to you is that its NOT the cam sensors at all.
Sadly if its not workong with a new sensor, it could be a number of things. Bad grounds all around, starter is short circuiting, fried ecu. Also your not giving the code, is ot JUST P0340/0345 or is there another "ghost" code.

 

Sorry guys ya the code is p0340 ......short circuiting starter mite cause this? Well once in a great while the starter will hesitate before starting but like VERY rarely....the grounds mite be a good one. Will add a new one and clean the existing in the am....really appreciate the ideas guys...will definitely share what the heck it is when we pin it down.

 

Can't really answer your question but can you show me the write up you used to clean the IVT sensors. Maybe even a picture of their location would suffice

 

I took them off and sprayed the holes out.....google image ivt solenoid you'll c it

 

Added 2 more grounds and no change yet about to do the starter

 

Go to the fsm linked in Ghosts comment. Download the EC portion, open it. Go to page 322 have at her. Thats for the 5.5 gen though. I dont know what page it is on the 6th gen.

 

Just changed the starter and no change again except now it hesitates before starting like every third start.like nothing just a click like a bad battery ground.....been spraying each connector with electrical cleaner as I go

 

That sounds like a bad solenoid on the starter. I would return it and just put the old one back in.

 

It asks me to select a year before the ec portion...and there is no 5.5 . Do I select 04 or 03?

 

It was the one out of my crashed max....I wonder if I should try a bran new one?

 

A good mechanic friend suggested I trailer it to the dealer and have them reprogram it so I can run the ecu out of my crashed max....is there a way I can do this ?

 

Yes, with nissan datascan II

 

Given up till I can get it reprogrammed will report with the results...thanks guys for the help
