Hello,

The ECM is located behind instrument lower cover. Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

2000 Nissan Maxima

I have a 2000 nissan maxima and they have done all diagostics and say that my computer is bad. How hard would this to be replace myself, by taking it out and reinstalling it. I have a company that is going to fix the old computer, I just need to know where the computer is located.

Thanks,

J-

The ECM (engine control module) is located behind the glove box, according to my 2000 factory service manual. You have to remove the glove box to access it.

My 2000 maxima was running fine and then one day it wouldn't start, engine turns over but does not fire. I pulled out a coil and plug(plug was dry) to check for spark, and there was no spark. I went and got an engine code reader tool at the local part store. The tool said it was unable to read codes. The guy at the part store said my ecm might be bad. Any suggestions on what might be the problem?
Anything will be helpful. Thank You.

Wondering if you had any luck getting your car fixed and what the problem was. Have a 1999 that's doing the same thing.

Yes, I finally brought the car to a mechanic, and after a few hours of trying to figure it out he found that it was a bad relay sensor or switch. A fairly inexpensive part but I had to pay little bit more for the labor to find the problem. Good Luck!

I was told that this vehicle had bad pcm power control module. It is NOT THE ECM, according to the mechanic. This problem was found by a master technician who does nothing but diagnose these problems. The PCM, as I was told is located under the dash, and the entire dash must be removed. It also has a bad wire in the PCM, not sure wether it's burned or damaged. The car will crank over normally, but will not start at all. I was told this will cost between 1600/2000 dollars. Not sure if it's worth it, but it is a very nice car overall and many of the other items, I.E. Struts, ac compressor, tires, water pump, brakes, have all been replaced. I repaired old cars many years ago, but this is something I'm not sure I can tackle. Would like your opinion as my only alternative is the junkyard.

Thanks,
Will

I'm sorry but your description makes no sense at all. A PCM and an ECM are basically different names for the same component. There is nothing called a "PCM Power Control Module"
The difference3 is that an ECM (engine control module) is a module that basically operates the engine controls. The term PCM (powertrain control module) is used when it is a module that combines an ECM and TCM (transmission control module)

Thanks for your reply. I will try and find the actual name for the part. Perhaps that is where I'm in error. I just know that this "module" is way under the dash and the labor required to remove and replace it is 8-10 hours. I don't t think I can justify spending this amount on a 14 year old car. Perhaps you know the name of this part?
Thanks

The car will not start. Was running fine, and then just stopped. All happened after ac compressor was changed. No fuel pressure but will start with starting fluid and then quit. Was quoted 2 grand to fix it.

Brand new to this site. Facing expensive replacement of ECM in my '02 Maxima SE. Car passed state mechanical inspection, but threw P0327 code & failed emissions. Mechanic says knock sensor OK. Traced problem to ECM. Found voltage drop from ECM after running engine heats up. When engine cools, normal voltage returns. Mechanic says ECM needs to be replaced. He can get remanufactured for less $$ but is squeamish about checking all the settings. Says dealership is better equipped to handle that, but dealer won't install remanufactured. It's shaping up to be a $2100 bill. So frustrating because car won't pass emissions, but it's an electrical problem. Any feedback is appreciated.

Hi NHmaxima,

The ECM is a very reliable component and seldom fails. Was the knock sensor replaced or tested?

I would suggest doing that first. At least remove and reinstall the knock sensor and check the wire sockets for contamination.

The part may already be out of production. You will need to check salvage yards making sure the one you get has the exact same part number. Also, the dealer should be able to check other dealers for "dealer old stock." (DOS). Labor shouldn't take more than an hour. However, the cost of the part is up in the air at this point. If a dealer finds a new one, they could charge up to 600 for it.

I was told to change the coils on my car and I changed the bad ones only. The 3 front one and the two back ones going from left to right. Would that one make a difference if that one was not changed> can that be the primary?

Also even when I chatnged the coils the car cuts off after you have driven it a good distance. After it shuts off if you ket the car sit overnight the next morning it would crank up like it never broke down; I was told to replace thye computer

Try testing the camshaft and crankshaft position sensors before you replace the computer.
