Ok this stupid "serivce engine soon" light went on about 2 months ago on my 2k max and it stayed on for about a week. Then all of a sudden it turned off now its back on and I disconnected my battery but its still on, does anyone know what could be the problem???? I have a couple of subs in the back, could that be whats messing with me???? I went to the dealer and hes like I need 100 bucks to see whats wrong hopefully I dont have to cough that up and someone here can help me.

 

$100 . That sounds kinda steep. Next time it is on, take it by to a regular mechanic and let him hook up the machine that reads the code to find out what is causing it to come on. He probably won't do it for free but I would think it would be far less than $100.

 

I have a 2k Max also with a Stillen Intake. Ive had the intake on the car for about 5 months. About 2 weeks ago the same warning light came on. I checked all of the intake connections and they seemed fine, but the light did not go away. I disconnected the Negative side of the battery for about 1 hour. This resets the ECU. After I reconnected the battery the LIGHT went away!

 

go somewere else, i charge no more then $45, maybe $50 if i dont like the person. but if im cool with u, ill scan it 4 free, but too bad ur in cali, if u find urself in az swing by, u can only tell what the probelm is by hookin in up with the OBD-II with the K2a key, thats with the snap-on ECU scanner, dont bother buying 1, u can buy 2 superchargers for the price of that thing! but there can be countless amounts of codes ur ecu and pick up. ur system shoudnt set any codes unless its a crazy semi- thousand watt with atleast 4 twelves or something and its draining the battery. u get the point. but if some1 charges u more then $50 its way too much, it takes less that 5min.

 

After putting on a FSTB today, I wanted to wash the engine bay and wax the maxima. well, being impatient, I started my car without taking the plastic bag off the K&N filter. The car instantly died and crushed the cone filter. Now the service engine light is on. What places can I take it to get the light off? I don't want to pay big bucks, but I will do what it takes. Will unhooking the battery work?

 

resets in 1hr? that's the quiest i've ever heard of. factory service manual says disconnect for 24+ hr.
definitely check out a local garage to get the codes read. Most AutoZone's here in SoCal will read it for free now. I think Kragen is setting up to do the same soon (I asked the manager of a kragen store).

ouch! be careful and take ur time doin mods. anyway it can take up to 24hrs is what ive heard if u disconnect the battery cables, and make sure they dont touch the body of the car, u dont wanna see what happens, trust me. it takes about 5min or less with the scanner but go to some auto shop u trust, or u have heard is good around ur neighborhood and get it read or cleared. if the place is legit they shoulndt charge u much at all, like i said any more then 50 just leave i still think thats WAY too much but i gotta get the scanner to pay 4 itself somehow. i wish i can scan cars all day, imagine the cash, $50 for every 5min. ill work like 5hrs a day and 5days a week, just punchin buttons...........sweet

 

I have a 2k max and my light went on then it would go off then on again took it to nissan. It was bad O2 censor and the ecu needed to be reprogramed. $500 bucks, but i didnt get it fixed. They said it would be ok for awile. 4 months later car runs like s*#t. Took it in on tuesday they read the codes and it threw out 11 different codes (that can't be good) they are still working on it. Can anybody beat 11 codes?

 

i have a 2k GLE with 35k miles and the first time the light came on at 20k, i reset, light came on now at 35k (have scan tool now) i pulled P0404 which is the cat low tol bank 1 (or close to that) TSB out for that .. took it to the dealer they reprogram the ECM and all set. he said most of the 2k and 2k1 are tripping up the lights like that and just need reprograming.

hope this helps,
neil

 

What scan tool do you have?

 

the best scan tool is the snapon scanner, its a professional setup and u can use it to scan hundered of diff cars. thats the one i have, but i work at a auto repair shop so its necessary. this tool is not needed by most people due to the fact that is $5000+ to start off with. u can do alot of **** with the tool, but for normal use id get the cheap scanner, were from i dont know i dont use that model. if u search u might find it ive seen it be4.

 

First thing to do is to check the gas cap and make such it is close tighty about 3 clicks. If that dont work. It could be that u have a bad O2 sensor, that's what the dealer told me about my 2k when that damm service light was on. If you are still under warrenty the dealer will fix it for free with no problems.

 

I had the exact same issue and the same exact fix. My gas mileage actually increased as well after the software update.

 

My SES light came on about 2 months ago, stayed on for about 1 1/2 -2 weeks, went out for the same period, then came back on etc....

Why does it keep coming on, going out and them coming on again? I am in no position money wise to bring it to the dealer...

 

This is usually due to an intermittent sensor fault. (O2 sensor going in and out sorta thing)

I had a Sentra that did that...it will come on for a month, then went out for a while...then come back on.

I traded it in when it went out..hehe

2k Maxes are known for their weak O2 sensors. Can you put back stock intake and bring it to dealer? It should be taken care of under warranty. At least it was in my case.

Mike.

 

My O2 sensor on bank 2 is bad, I think. I got codes P0158 = Downstream O2 sensor circuit slow response and P0159 DownStream Oxygen sensor high voltage. The SES light came on after I installed my stereo system. My power wire is 4 gauge. Could this be the reason why? I have almost 50,000 miles on my car. Does the powertrain warranty cover sensors? I doubt it but just curious.

 

Why would your dealer charge you $100? Shouldn't you still be under the powertrain warranty (I'd guess that it was 5 years/60K miles for the 2K model year)? I can't figure out why people here want to cough up money when it should be covered.

 

That's my plan.....I have to dump this thing before it's worth less that what I owe on it. 64k and 3 sets of rotors and now this....and the tranny slips at the worst times now and then...ugh..

 

Well, it was under warranty in my case, I had 30,000 miles at that time. I think, your stereo installation is nothing to do with SES light since O2 sensor is part of engine management system and doesn't even require external power supply. It works as galvanic cell between exaust gases and outside air oxigen. In your case it seems just coincedence. Very long shot - powerful stereo in the trunk theoretically could cause false sensors reading if it uses car body as ground wire. Never heard about it though. My car was having worse mileage at that time too - it was burning about 10% more gas for the same distance than it does now.
O2 sensors should be covered under powertrain warranty because only purpouse in their lives is providing info for adjusting engine fuel/air ratio. BTW, I am stock from engine mods point of view.

Mike.

 

Thanks Mike for the input. I am going to change the ground to a diffrent point to see if it makes a diffrence. I do know that their is a TSB for the O2 sensor and that it mentions the two codes I got.

 

My Service Engine Soon light also came on a couple of weeks ago at 36,200 miles (just out of warranty)..... I checked the gas cap and after to fill-ups and about a week the light went off by itself and then came back on later that same day. I took it in to Hamon Nissan in Texas City. They pulled the codes and sent results to Nissan. Codes showed front and rear O2 sensors as malfunctioning.... HOWEVER, there is a TSB this isuue for 2001 models and resolution only requires an ECM re-program as mentioned in earlier posts. Total cost..... $120 bucks. I'm not sure, but those who have been quoted $500 (!?) need to go somewhere else! As I understand it, re-programming only involves the dealer downloading the software image to a handheld device, connecting it to the service port on the car, and uploading the new software to the ECM (similar process to re-flashing the BIOS on your PC). Shouldn't take more than an hour. Anyway, we'll see how car performs after the software update. I do keep a very close log of milage. I'll post any significant change after a few fill-ups.

 

Had the exact thing done 2 weeks ago for the same cost (except I made a stink with 1800-Nissan1 and got them to pay 50%.) SES light came back on yesterday. Any ideas before I bring it back?

 

like someone said before, take it to autozone. They do it for free. It's even on their website. You can save a $100 that way.

 

Tex (and anyone else who has paid for reprogramming),

Go back and get a refund. Any work (TSB or not) done to an ECM aka PCM/ECU is covered 100% under federal emissions warranty for 8 yrs/80,000 miles (the cat too). Repairs include software updates and the labor to re-program. The update is listed as the "part" installed. You may have to pay for the rest of the repair, i.e. those O2 sensors that you mentioned.

Anyway, my service writer tried to charge me for reprogramming at 65k miles even with TSB NTB00070A in hand (SES/Code P0420: 3-Way Catalyst Function). The ECM was incorrectly measuring emissions and simply needed an update.

His first line of B.S. was to correct me by referring to the ECM as the PCM - Powertrain Control Module and that it was covered by the Powertrain warranty to 60k miles. Fortuneately I had other customers within earshot. I pointed to my warranty booklet and showed him where the "PCM" is covered by Fed Warranty. He then said the labor was no-charge but the software update wasn't. I tell him the update was the only way to correct the malfunction so it had to be covered. Since I'm not leaving quietly he calls Nissan Cust Svc to verify the warranty and to save face.

Also, don't rely on Nissan's TSB's to mention warranty status and conditions. Clearly some dealers aren't. Good luck.

 

all three autozones that i've been to in CALI say they do NOT perform the ecu code check anymore

 

My 2k SE does the exact same thing, goes on for about a week or two, then goes off for about the same time. What happens if you don't do anything about it or just leave it like that. Could that do any serious damage to the car if I don't get it fixed??

 

I eventually took it to the dealer and they "fixed" it. At least i hope they fixed it and didnt take out that yellow bulb that flashes the service engine soon.

 

Actually, as it turned out, the whole thing did get covered under warranty. I made my original post just before I went to pick up the car from the dealer. When I got there the Service Writer said the whole this was covered. I was so happy to not be shelling out greenbacks that I did not inquire about what portion of the warranty covered the re-program. In any case, I have logged many tanks of gas since the software update and can report approximately 2.5 mi/gal increase in fuel efficiency with no decrease in performance! (I have not quantified any performance metrics.... maybe it's the clean car syndrome... your car always seems to perform better after a nice bath and polish job... come to think of it, so do I -- hehe). But the milage increase is documented, and I'm happy about that. Also, the light has NOT come back on.

 

My Check Engine Soon light popped on last Friday at 37,900 miles. I took it to the dealer this morning. They reprogrammed the computer and had me out of there in less than an hour under warranty.

 

Just found this forum today as my SES light just popped on wth 28K miles on the clock.

Thanks to all the previous trailblazers for the info. I wish I had found this page a year ago re: warped rotors, rear door wind noise and a noisy right front strut off my driveway. My Nissan dealer (former to be?) is going to get heck...
