I bought this car 3 months ago! It has been freaking nightmare.. The throttlebody and IAC went out! That was fixed.. I have 2 o2 sensors that are bad and neutral safety switch going out! There's a problem I'm currently having leaving scratching my head.. WTF??? I took off panel where the odometer is to make sure everything is plugged in and that's good! Here's the problem speed odometer stop working! The gas and temp and mileage still works though but if i drive the car for long period of time it will just stop but after letting the car sit for little bit it comes back on.. What in the hell??? Each time it shuts dwn the car runs horrible!! Any suggestions??

 

get a odb2 scanner and report back with the codes

when your iacv went out did you inspect the ecm? unfortunately it is common for the ecm to be damaged when the iacv goes on these cars.

maybe new vss will solve speedometer?

 

[QUOT
Only codes it's throwing for 02 sensors.. I kinda had feeling about the ECM but hoping for cheaper and easier fix.. That's not good! I bought this car for 1900 and gonna cost wat more to fix.. It has a lot of mechanical problems! List full

Sounds like VSS is bad.

 

it's not too hard to pull the ecm to check it, might be worthwhile to make sure that's not causing your problems. they can be repaired for about $150 +/- so it's not the end of the world

 

What is VSS?

 

150? Wat if it is? They don't have to reprogram? By time I fix 02 sensors and neutral safety switch and motor mount.. I say I've reached Wat I paid for it.. I LOVE the fact they unhooked battery to erase the check engine light.. I got royally ****ed on this car..

 

Vss=vehicle speed sensor

 

I just googled.. Thx.. I'm female so I'm in learning process.. First Nissan ever owned and maybe my last.. Didn't think car could have so many problems all at once.. Urrrr

 

no, no reprogram needed if you go the repair route

 

Really?? Ok that's good to know! Thx

 

Well I think any 15yo car has tons of issues with wear items and such, it wouldn't be so expensive if you could hunt down the parts and perform the work on it yourself,

 

I maybe female but I can Google and learn.. If i can change tires, light bulbs.. I can Google and learn.. 😅

 

Good luck with finding oem vss sensor. I just had to get a used one. I went to my local nissan dealer and the part for 2002 at least has been discontinued. I didn't think to have him try a different year same trans car though. I'm assuming it's the same. Nissan is really dropping the ball on older parts availability. Good luck.

 

You know why that is right? Their trying get oldwe cars off street.. Their not making money unless their sticking it. To You with finance charges on new car.. And or the ones that are still in the year range to finance..

 

Junkyard parts, ma lady. Cheap or free

 

Yea. Thought about that too! I'm down for freeeeee! Lol

 

If the car idles properly, then the ECU is fine. I would still do the TB coolant bypass.
Definitely let us know what the codes are.

Not that you should trust internet people , but maybe a member is in your area that can help.

 

My car not running good at all.. Its fine at first but longer car drives worse problems.. Meaning.. Hesistates when giving gas.. When Its sitting it struggles to keep idol and of give gas and let off it does but starts back up! Same process starts over

 

First things first:

• Get yourself an OBDII reader. You should have had one with you when you went shopping for the car! - you would have avoided this mess. You can't work on this car without one. You can get one for as little as $15-$20 on Amazon.com, for example

• Re. your car dying/hesitating as it warms up. You have a bad sensor somewhere (probably MAF, or Cam/Crank, or perhaps other); when the car is cold, sensors have little impact as the car runs off pre-sets, but when the car warms up, the sensors are in control. You need ODBC reader to find out which sensors have problems.
• Re. your Neutral Safety Switch. Not expensive ($27-$35), you can get one here: http://www.rockauto.com/en/moreinfo....359222&jsn=436
• Re. your VSS. Get a replacement (about $25) here: http://www.rockauto.com/en/moreinfo....359222&jsn=455
• Re. your IACV/TB. You said it "went out and was fixed". Make sure you understand - just in principle - what the issues are. This note explains: https://drive.google.com/file/d/0B6O...psNVBqUVk/view .

So, I suggest: Order yourself an ODBC reader. While you wait, clean the MAF (it seems very likely it's either outright bad or at least dirty; instructions here https://maxima.org/forums/5th-genera...10-w-pics.html). Then, depending what codes you get, order all sensors you'll need from Rockauto.com. So, perhaps it's not as bad as it all looks right now. With a bit of luck, you could be in business for perhaps couple hundred dollars.
