Thanks to all who have responded so far. I did the battery disconnect a couple months ago but the issue keeps coming back. The dealer says the ECU is posting P0420 and P0430 errors. The ECU was flashed in 2002 so it has the latest code with the fix for NTB00-070a (Service Bulletin to address computer incorrectly posting P0420 code). I checked with a 3rd party shop...and they say they can most likely get the code to clear by replacing the front converter assembly for $965.00 (price includes all fees, labor etc.). They say most of the time this repair will clear the codes without replacing any O2 sensors. However, they advise to do the front converter assembly repair, reset the computer, and drive it for awhile ...if a service code comes back then look into replacing the applicable O2 sensor. But Nissan dealer says if your going to replace Catalyst parts to clear the codes then they strongly recommend replacing the entire system (front cat...back cat ...and 2 Oxygen sensors for $2865.00 -includes 1 free coffee and a complimentary lobotomy). LOL I think I'll try the 3rd party solution unless anyone has any other proven repair strategies .... but it seems like, generally speaking, you just don't get enough information out of the ECU codes to guarantee a fix -unless, as the dealer states...replace the entire system Otherwise a great car that I would love to keep.

02 sensors are not a common failure on this model. The P0420 & P0430 are catalyst failures not 02 sensors failures. Ignoring a P0420 & P0430 can cause engine failure.

I just bought a used 2007 Maxima SL with 76,500 miles. The oil has been changed every 7500 miles per manual. Tires were just changed at 71K. The owner tells me the brakes were done at 50K. The air filter was changed per factory specs. My question is does the CVT fluid and radiator coolant need to be changed anytime soon. Also, does any other maintenance need to be done. Thanks for any reply.

I seem to have the faulty ignition coil problem with my 2001 Maxima. My mechanic said that I should bring it to Nissan since they can figure out which coil it is so I would not have to replace all 6. I called Nissan and they said I should replace all 6 because if one is bad they are all going to go bad, etc. After some internet research and fidning this thread I see this is an ongoing problem with this car.
My husband wants to change the coils himself but I am not sure which ones to purchase or where to purchase them from? Can anyone help me with this? Also, is there a step by step guide he could follow? He is pretty good with cars but has never done a coil replacement before.
Thanks for any help you could give me!

Try rockauto.com, they have the parts you are looking for. The coil cost from $52 to $66 each depending on if it is the front or rear coil(3 front, 3 rear). I have ordered several items for my 07 Prius, and I am now looking to order other parts for my 07 Maxima. Their prices are very reasonable.

Turned the car off.

Replacing all 6 ignition coils is very expensive and bull---t ! To find out which one is bad try this. With the engine not running remove one plug wire from the plug and then start the car up to see if the engine runs rougher. If it does that means this cylinder is running ok. Repeat this on each cylinder until you get a cylinder that does not run rougher. This will be the cylinder that has the bad coil. The coil is connected to the top of the plug. Remove it and go to Auto Zone and buy a new one. This is what I did on my 2000 maxima last year and it's still running like new. Total cost about $60.00.

Try infinitipartsusa.com for OEM ignition coils. They are about $75.00 each. I recently bought 6 ignition coils and spark plugs for 514 delivered. Will change the coils tomorrow.
2001 I30 and maxima are identical cars.
Another source is courtesy nissan for OEM coils.
The process of changing it is very simple. Details can be found at
If you are interested in complete service manual they can be downloaded from
best of luck
