Same story as everyone else, SES light went on, went to AutoZone to have the code pulled, and I didn't get as much info from the guy as i should have. He told me all i needed to know is that the problem was coming from "Bank 1, Sensor 2." So which one of the oxygen sensors is that? Or do I need to go back and get more info?

if u want i have one brand new bosch 02 sensor, 40 shipped if thats what u end up needing.

Irl4512

I have to figure out which one it is first...then worry about replacing it...

Irl4512

And then another question...the guy at autozone reset the SAS light. Do I have to wait for the light to come back on for them to pull the code again, or can they do it when the light isn't on? Thanks for any input.

Irl4512

bump...need some help

kclmax2k1

could you remember the code?

Irl4512

No...that's the part where I didn't get all the info I needed. I was hoping that the info that I had would be enough. I'm guessing it would be the rear sensor on the drivers side?? I am going to call my local dealer tomorrow and see if they can help me out.

You probably don't have Adobe Acrobat installed on your computer, or maybe not the latest version. Install that program and the link should work. It does take a little bit to load especially on 56K.

I would print out the TSB and take it into the dealer if you have less than 80K on the car. It will be covered under warranty for that many miles. If you have over 80K you can try replacing the oxygen sensor, but it may not be that. It could be your ECU which needs reprogramming, and only the dealer can do that (unfortunately). If you take it into the dealer for diagnostic, its around $85 and I believe they will cover the ECU reprogram, depends on the dealer. But if it's your oxygen sensor then you are SOL b/c you will have to pay the diagnostic fee plus the oxygen sensor replacement if you choose that route. This is if you have over 80K miles.

Irl4512

I only have 43k on the car...so if it were covered, that would be great. The guy at autozone reset the SES light, so it isn't on anymore. Are you saying that they might reprogram the ECU at no charge considering my mileage? I was hoping that this might fall under the 80k emissions warranty. I will give my dealer a call...they have been fantastic to work with the other problems I have had with my Max.

Irl4512

Ok, called the dealer and they said it would not be covered by my warranty...that only applies if it is a California car with Cal. emissions. So to replace both rear o2 sensors and reprogram the computer...$450 or so. Not what I needed to hear.

KCLmax2k1 - Great Link, Thanks

Question - I have a 0158 code which is Bank 2 Rear. I deleted the code. It is a high voltage code, could that be a one time error? It happened on a 4 hour drive 2 weeks ago and the ses hasnt come on since. If I do replace the o2, do I need to get the ECM reprogrammed at the dealer?
Thanks

Irl4512

A friend tells me that where the car was purchased makes no difference...all cars are Cal. emissions (aka federal emissions), so this should be covered under the 8/80 emissions warranty. Now I just have to wait for the SES light to come back on, take my TSB in, and see what happens!

I believe the SES code is stored in the ECU so you don't even need to wait for the light. I would take it to a different dealer than the one you called and have the TSB in hand to show them. That should work. If they give you flack, then tell them you will call NMAC about it.

Irl4512

What is NMAC and how would I get in conact with them?

Good luck in getting the O2's warranted. O2's are 3/36. If you have a friendly dealer you might get it replaced under the 8/80. One or two have...the rest of us have gotten hammered for the cost of it.

If you are a DIY'er...you can save good money by purchasing it from DAVEB and installing it yourself. Its very easy. Otherwise the dealer is going to try and soak you for 3 hours labor plus parts (heavily marked up) .I was quoted in excess of 400 clams and I laughed at the guy. I had him break it down and it was 150 for EACH O2 (TSB REQUIRES both be replaced ) and 3 hours labor.

I performed it myself and did both, reloomed the wires in the factory positions, got a wrench at autozone to perfectly fit the O2 and it still only took me 1.5 hours. But remember .7 hours is dedicated to the ECU reflash.

Good luck man.

BTW, my guess is that you threw a P0140 code.

kclmax2k1

I got p0138 and p0139 and replaced the o2 sensor by myself. Replacing the sensor was easy, however, took out the old wire reloomed the new wire in factory position was not so easy. A smaller arm and hand may help a lottttttt.

emhc1999

If you diy, do you need to get the ECM reprogrammed?

Irl4512

So did you replace the o2 sensors with the white and red harnesses? Looks like those are the 2 according to the TSB diagram. Did you have to go and have the ECU reprogrammed then when you were finished?

Colonel

Yes I replaced both O2's (red and white wire jackets).

Yes, after argument, they programmed my ECU free of charge.

To give you my "timeline" on what happened.

1) Spirited ride on highway throws CEL (in my mind I knew it was an O2)
2) Went to Autozone, they pulled the code and handed me a printout ( P0140). Yup...O2.
3) Printed out and read up on the TSB. (link above when it works again)
4) Took it to Nissan, was quoted and ABSURD amount to repair.
5) Haggled with Service manager to do the ECU reprogram for free (covered under 8/80) but I have to show a receipt or replaced O2's with Nissan tags. Be careful as mine wanted to charge me the full diagnostic service even though 1/2 of it was covered under warranty. I argued until I only paid half of it.
6) Purchased O2's from DAVEB (who also verified the accurate quote of warranty of 3/36 on the O2's).
7) Installed myself and took to them to install. I asked for a model number printout pre and post of the ECU flash. Model number makes up the part number as explained in the TSB.

I wanted the ECU flash for two reasons:
1) New code for O2 boundaries
2) New code for updated MAF. ( I replaced same time as O2)

To me, the O2's probably DON'T need replaced. Nissan writes it up that way to cover their ***. I was trying to get an ECU reprogram only...but they would not. I was hedging my bet that the code was to tight, not allowing enough tolerance. But I was unable to prove that bet. Isnt Nissan service glorious!

Irl4512

Makes me wonder if I really need to do anything about this yet...there are no signs whatsoever of performance loss, hesitation, sputtering, hard starting, etc.
As a matter of fact, my car did over 26mpg on a 300 mile trip this weekend (about half way there is when the SES light clicked on). Coincidentally enough the light came on at the EXACT time that my cruise clicked off. Anything to be concerned about with that happening or just a coincedence?

Colonel

The cruise off/CEL on might just be coincedence.

If you really wanted to gamble, pay the .7 hours (TSB labor cost requirement) to a reputable dealer ( I know...that might be hard to find) and just get the updated ECU. That would be FAR cheaper than buying two O2's.

Then if you have someone that can clear the CEL for ya...when/if the CEL goes off again you can just replace the O2's and get the light reset and be on your way. Only issue with this is you might possibly pay for the entire repair bill.

Let me know what you end up deciding to do.

Irl4512

Not a bad idea. Talked to a service guy at another local Nissan dealer and he said to wait til the light goes on again, and he will see what we can work out. Would they really just reprogram the ECU? The way it sounds, the O2 sensors usually arent bad anyway, just the ECU saying they are bad. That would seem to be a decent resolution then...

Colonel

If you can get them to reprogram the ECU as part of warranty (no charge to you) then do it for sure.

If you pay them the .7 hours, they will (should) do it without a problem. If they are reputable.

I am still of the camp that the O2's DO get a tad lazy as they get older, but they should not be "done" prior to 60 or 70K miles.

my dealer told me it was covered for 3/36. Couldn't do squat for me. I'm getting an o2 simulator soon just as everyone else with this problem should

I dunno guys, i agree... i have taken a trip to michigan from newyork and everytime i do it the ses light comes on about some BS with the o2 sensor. the first time i was really annoyed and ordered an o2 sensor because i didnt know. Now i know that its not the o2 sensor that is going bad, but something with my car that when i take it on long trips over 4 hours that the light will be thrown. I bought a new maf and the light went away, so to test it i took a drive to ohio, and back, (i had something to do there anyways), but the light went on. Then i came back and drove it for a couple of days and it went away. It has to be the ECU needing reprogramming. Im gonna take it to the dealer with warranty book in hand and show them the code 0160 that i keep gettin along with the tsb. If they dont fix it, ill just cry like a baby until they do.
