Thanks to everyone who has posted a comment on this site. I am also a victim of the Maxima Check Engine light. I have replaced O2 sensors, Mass air flow meter etc. Alas my light is still on. The car drives fine and everything seems OK, but I am now worried more problems may arise. To the person who posted on Dec 21, I had the same problem with my car. The problem went away after I replaced the Mass Air Meter. Do this yourself it is a very easy fix, just a few screws and your done. ($80-$110 for the part, Dealer will want about $400 for the job). It is also a good idea to disconnect your battery for about 2 hours to let the ECM reset. This might also make the check engine light go out, at least for a little while.

Wow-- I just sold my 2001 Maxima to my daughter and she called with the service engine light on and they said it needed O2 sensors--- reading the above comments has me nervous that the $900 for the O2 sensors will not be the end of the expenses with the 97,000 miles she has on it. I too thought the Nissan would be a great investment not sure-- A confused father what have I done!

If your check engine light does come on the first thing to do is get your codes read. Most Auto Zones will do this for free. Murray's will let you buy the OBD scanner then return it. If it does turn out that it is an O2 sensor they are fairly easy to replace. I have replaced both front side sensors on my Maxima. The first one is located on the front of the engine attached to the exhaust manifold. You will need to get the appropriate sensor socket (Auto Zone should loan you one if not they cost about $10). The second sensor was a little tougher to replace. It is located on the underside of the engine on the rear exhaust manifold. It is hard to reach this one with a socket so I cut the wire than used a Open end wrench to get it off. Time consuming and tedious yes, but with the cost of the sensor (about $110) a lot less than the dealer wanted. Hope this helps.

I have a 2000 maxima and you name it, I have touched it, just short of parking it on the dealership lot and telling them to keep it. My solution has been to keep a hand held ODBII scanner in my glove compartment, and when the light comes on, check it, if it is not a safety issue, clear it and go. The scanner I use is the (ACTRON, CP9135), small cheap and keeps me away from the dealer, and less frequent trips to the car part black hole. I feel all of your pain; my next car will not be a Nissan product.

Did anyone have a problem with their "IDLE AIR CONTROL VALVE- AUXILIARY AIR CONTROL VALVE. (IACV-AAC) CODE P0505.

I have a 2000 GLE right now with the SES light showing code P0505 IACV. I haven't replaced anything yet, because reading up on everything, I'm not sure that paying $300 to have the IACV replaced will actually take care of anything.

Yup, I have a 2000 Maxima GLE with 85K miles - have replaced two O2 sensor three years ago, an idle air control valve a year ago, and now have the same idle air control valve problem again where car starts fine, but will not idle unless you keep you foot slightly on the gas. Works fine otherwise.

Only problem is my electronic control module does not work now so even have to replace it as well b/c the ECM is needed to fix the IACV problem. YUCK!

Owned a 1994 Maxima and never had any issues. This 2000 model has eaten my lunch. Time to trade it in and take the hickey. Ouch.

Maxima Check Engine Light. This light has been on for four years and I just ignore it... when it is time for inspection, I pour a bottle of Guaranteed to Pass or GTP into the fuel tank and the light goes off after several hours or a few start and stop cycles. Then immediately go and have your car inspected b.c. the light comes on within another day or two! Walmart - 6 bucks!! Don't waste money on getting this fixed, it is impossible... if the car runs OK, just ignore it!

I have a Nissan Maxima GLE 2000 Model. I had the check engine light on. Found out that one of the O2 sensors bad and replaced.

I was told by the Dealer that he did the reprogramming after changing the sensor.

Is it required? Does anybody else have similar experience?

Wow, these comments have shed light to the recent problems I'm having with my 2000 Nissan Maxima. I just got the car 6 days ago and now I'm already having problems. When I first test drove the car it wasn't running too good. I told the dealer and he found that one of the Oxygen sensors had to be replaced. I test drove it again and it ran like a charm. 3 days later on I started the car to get ready for work and the car wouldn't stay in unless I kept pressing on the gas. I know you shouldn't do that with the temperture so low, but I had to just to keep the car on until it warmed up. Thank God for my extended warranty. I'm guessing now I have to replace the mass air flow meter. I must say these comments are very helpful.

Maxima 2000 GLE, same problem, go figure.

Anyway I am going to my mechanic Friday and am going try to fix it. Thank you everybody for your comments, I personally don't care at this time whether the light is on or not, but I am have a big issue with it stalling all the time, now it does it when I am simply sitting at the light in "drive". I am hoping its the MAF problem. Everybody sign the petition and if you can get something of it please post it here.

Thank you.

I have a 2001 maxima GLE. I got the P0505 code that some of you have experienced. Its only been about 3 days, but will do the following things: replace/clean throttle body, IACV, and change the MAF. Can someone who has this code and got the SES light to go off, please explain what you did to fix the problem. Also my symtoms where low idle, stalling from cold start, and sometimes erratic idle when the engine is warm. Please post some of you experiences so we can help each other out.
