I brought my Maxima in this morning due to a "Service Engine Soon" light that's been on since last week. It just came on all of a sudden. Anyhow, the owner's manual says it may be an emissions problem...and it was. However, the service mgr. at the local dealer advised me that they have to reprogram the ECU with TSB #NTB00-070a and that they needed my car for most of the day to do it. He didn't go into great detail, but he said it had to do with the "3-way catalytic converter"...? The service mgr. hooked me up with a FREE rental car though. That's a first.

Oh well, has anyone else encountered this minor problem?? I also showed this guy the TSB for the Fuel Cut-Off and he said it would be included in the TSB that they were putting on. He sounded like he didn't know what he was talking about though. Your input please...thanks!

 

Some have had a problem with their main cat and the service engine soon light. Looks like they are taking care of you though....that is cool

 

I don't know how cool a tan Ford Taurus is, but yeah I was surprised when he said they were going to pay for a rental car. I tried doing a search on this website about this problem, but no dice...

 

yeah, I hear ya.....but a tan Taurus is better than no car....

 

I have a 2001 Maxima with about 95,000 miles on it. A few months ago the check engine light started turning on for about a day or so at random intervals. Every time the code was P0420, and after doing a little searching I found out that TSB #NTB00-070a will supposedly fix this problem.

So I took my vehicle to the Jim Click Nissan Dealer here in Tucson (first time I've ever been there) and they told me that the O2 Sensor, front pipe, and Catalytic Converter needed to be replaced (which would cost $1400). I told them to not do anything yet.

I did a little more searching and found the actual TSB document and it says that the first and only diagnostic that they should have done is to check the ECM Part Number to see if it is faulty. The TSB document says that the ECM P/N can be found on the Consult-II self-diagnostic print out, but is there some way that I can find the ECM Part Number myself to see if they're just trying to rip me off?

 

What did the dealer charge you for the service?

 

I know that this wasn't what you asked about, but the dealer told me that since the vehicle was out of warranty that it would be $105 to do the diagnostic and then to reprogram the ECU.

 

WTF did you bring a 6 year old thread back for?

 

Are you under emissions warranty? Must be nice...lol i got quoted the going rate as well, around $1372 for a "front exhaust tube", 2 o2 sensors and a reprogram, at around 110,000 miles. I'm at 123 now and the light goes on and off pretty much on its own. What are you guys seeing for gas mileage? I'm at about 19.5 combined :/

 

Seriously, we can’t flame idiots but idiots can dig up 6 year old threads and post NOTHING USEFUL

 

IB "like your 2 other posts were useful"

 

Whoops i totally didnt even see the date

 

Go get some vag Itll make you feel better

 

Last tank was 21.5.

 

usually 19.8

 

24 here

 

That is what I was getting initially when I first bought the car and was enjoying the 85 hp gain over my last car (Mazda 626).

I am interested in seeing what I'd get on a road trip at steady freeway speeds. I reset the mileage computer on the freeway and over a 45 mile drive, averaging between 72-78, it was showing 30.5 mpg, but then again, we all know how optimistic that mileage computer is.

 

Hard to follow the new rules ehhh? lol We should just stickie everything lol

 

Get a y-pipe its like 200 bucks o2 simulator 25, strait pipe to replace cat 30 bucks of ebay = u save 1145 woohoo = money for mods
Or for 1400 you can get cattman headers and a cattman exhaust son woohoo
