This video I made after hours at the dealer I work for. It's best to get these parts new, not used to ensure this repair is done properly! Getting used parts you run the risk of them not working and costing you more money.
The scanner used is the Nissan Scan tool called consult 2. This is a Older Nissan Scanner that is not used very much any more. Mainly on these older cars.
makes me remember when my service writer sold a fuel indution service on a maxima and i unplugged the throttle body, sat ther for an hour trying to relearn the idle with the key/gas pedal method.
Motor mounts is a similar issue where it damages the circuit that controls the engine mounts. But they won't cause this code. Simply unplugging the engine mounts normally works.
after replacing pcm most newer cars need to be reprogram for the factory security alarm system ,do you Know if is ther a tool will support to program all manufacturer or does nissan use ther on ,for ,gm etc. thanks
Hey there i know how to turn a wrench it looks fairly easy to do. I dont have a relearn machine. If i replace the ecm as well as the IAC can i drive it to the dealership for a relearn or will that blow the ecm again. Trying to be as careful as possible
EXACTLY! On a 2001 nissan maxima auto i have a IACV taken apart right now and its full of radiator coolant in my intake and down to my air filter. Now with that said is this a defect of the old IAC leaking? and is this what burns it out?
I don't recommend repairing the Ecm, I have never seen them work right after repaired and can put you back at square one. But if you do want to try to send it out for repair, that is up to you. Some repairs don't require keys to be programmed, some do. It's one of those things that you won't know till you get it back from being repaired. If the security light is on solid when the key is turned to the ON position, that means the keys will need to be programmed. Thanks for watching my video's.
I just bought a 2000 Maxima. The old IACV was in the backseat when I got the car home, and it tested bad (short between pin 1-2 and 4-5) but the new IACV that the previous owner installed tested good. Can I assume the PCM is good?
I took the IAC housing off the throttle body and didn’t find any coolant in the IAC ports, gasket still looks good. Connector didn’t look damaged but I didn’t think to smell it. I’m gonna do a coolant bypass and hope for the best. Thanks for your help
Yes, the Relearn is most likely the Idle Relearn. If your still getting the P0505, then there is a good chance the Idle Relearn didn't complete. If you care to speak to me more about this, go to JustAnswer and ask for Jay.
Yeah, it's Reman from the dealer. They work fine. It's the repaired ones that never work, that is what you have to watch out for! You should be fine with a Ecm from Courtesy Nissan!
what ids the name of the company or where do I buy it? do You know if after replacing with other pcm does this software programs immobilizer as well programming keys? thank you
Hello, CAN I DRIVE WITH THE IAC VALVE UNPLUGGED? I replace the ECM and I got a full throttle control body from a junk yard but it seams that the valve is not good here either. however, the engine light did not turns on but the scanner gives me the code P0505. it could be that the ECM is good or bad, I don't know, I think that it is good because of an early discovery. the car is parked now but at this point I only want to drive the car until I replace the Valve and figure out what I want to do. So, can I without braking the new ECM?
So you think it would be OK to get a remanufactured one from Courtesy Parts though? I don't think I saw a new one. Yes, RE: the stick, it took me so long to get it, and I love it, but there weren't many out there. Although, surprisingly there were 2 white 2K MT Maximas here in Oxford, MS.
I have a 2000 Maxima SE (manual transmission) and am now on my 4th IAC. Admittedly the first 2 were not Nissan OEM, but the last one was. Nissan dealership said my ECM was OK when I had the last IAC installed. I don't know if I trust that dealership too much. A year and a half later, it is dying again and throwing the code. I got my ECM taken out and was going to have it sent off, but I don't see any damage (certainly not like your video 5). I hate to buy an ECM if I don't need to. Ideas?
Jay, I was wondering how to program the key without that scanner you have? that scanner appears to be expensive to buy to hopefully perform this at home. I found a relearn proccedure without the scanner. By the way, thanks for all these videos and awesome job!! Eddie
question...if your ecm is burnt...would it still be able to give a correct reading on a scan tool? i have an 01 maxima that couldnt start at all...i changed two gears on the fly wheel and it started running with one crank....a week after that, i began having the problem where it began to run rich...i then had to change the ecm according to what a local mechanic told me, he said that "the ecm is the problem".... but even after the ecm change, the problem still exists...the code thats coming up in this new ecm is the p0505...for the past few weeks ive still been having this problem, and recently it began to get worse, it was just dumping fuel like crazy, running super rich, smoke every where...just about 3 days ago i had an incident where the car suddenly lost power and underneath, the muffler was glowing red...the day after, it would start and 5 to10 secs into running, it just stalls out like its out of gas or something...but theres a half tank in there!!!? and now it wont even take acceleration from the pedal...one mechanic said that the problem may be that my fuel pump is bad, one said that its my injectors, one said that it is my catalyst converter, one even said that there may be a wireing problem...im so confuesed....i had the car to these guys and spent a whole heap of money... but none of them can seem to figure out whats wrong with my car :-(...but looking for answers for myself i found u......plz!!!?? i really need help, i dont know what to do or what to believe anymore...
i see you used the CONSULT to program the KEYS and RESET the IAC...since i will do the ECM and IAC at home...can i get a locksmith to program the keys and take the car to a nissan dealer for the rest????
The outside numbers on the Ecm case is not the part number. As for a Manual Trans Ecm, they are hard to come by since there wasn't to many stick shift ones. Courtesy is the best place to get the Ecm in my opinion. I know you don't want to spend, but this is what needs to be done. Replace the Ecm and IAC to resolve
question ... i dont have that code yet but would it be ok if i change the emc and iAC before the code popes up i mean i have 114,000 on my maxima and everything is factory would it be a problem if i change it ?? or would it be ok and prevent the code from popping up ??
Some lock smiths can program keys so it's important to inquire on that when you call a mobile locksmith. But they can not do the idle relearn. It's best to use the scanner to have that done to ensure the repair is correct. If you can't get a locksmith to program your keys, then the car would need to be towed to the dealer to have it done for you with the idle relearn.
@@mistyedavidson7781 The Idle Relearn is important, because it verifies the repair. So you want to take it to a dealer or a shop that can do it with a scanner.
Also, I have taken my old ECU out. I haven’t opened it up yet, but I’m going to this weekend. If the damage is minimal, can I purchase a STA509A mostet to replace the old one & see if that does the trick. That way, I won’t have to get another ECU, nor will I have to get it reprogrammed…right?
@@mistyedavidson7781 The chip repair if that is all it needs, will most likely require programming to be done regardless. But it's best to be repaired by a ECU Repair place to be properly tested when repaired.
Great video!!! I have a question. I have changed my IAC, MAF sensor and my ECM. Went to nissan to have my keys reprogram. Nissan also did a ECM relearn. Is that the same as a Idle relearn? I am still getting the PO505 code. Any Ideas? thanks
i have replaced my ECM and IAC. took it to nissan, they were able to reprogram the key but not able to relearn the IAC. they told me that i needed a new throttle body. New throttle body is on. when i start it the rpm drops. will that be corrected once the IAC is relearned?
I have an 2001 maxima.. having the stalling starts and getting code 5050.. i was wondering where did u get you ecu and iacv. I found an iacv on ebay for $70 and a repair man for the ecu for 100 dollars..is that a good buy or w
My ECM is an A56 P33. It is for an MT, one of the very early ones. Do you know where I can get an ECM as a replacemet? I see I think a remanufactured one at courtesy Nissan. I really don't want to spend a ton on one, but I purchased the max originally and I only have 75K miles on it.
Hi I have cuestion! I have a 01 infiniti g20..I replaced the IAC and ecm. I reprogrammed the key...the ecm I ordered it true a junk yard with vin # and everithing ...do I need to reprogrammed the ecm also? That's what the dealer told me but I didn't see you doing that on your video!! Please let me know I aprecciate your time! Thanks!
do I have to change my ecm if its not burnt haven't checked it yet but went to advance they said it was iacv from code from enigine light. So I called Nissan mechanic from my dealership and they said if ecm was blown it would not run so im goin to check it don't know I have replacement iacv but haven't installed yet I want the perfect way to handle this to save money let me know its idleing high and revs up and down and some times it stalls out and doesnt have barley any throttle response let me know wut u think it is
My ECM burned, and I bought ECM and NEW IAC and Throttle body. Please let me that how can I change Throttle body position and how can I install it? or do you suggest that I take car to mechanic? Do I need to change Throttle body to new one or I must change with IAC and ECM? Thanks
Ok, what scanner or pc hardware and software do I need? My car has 43k miles (2014- I just got it); looks like the former owners had this problem for a while and they couldn't figure it out. I am in mexico and not even the dealerships know what they are doing when it comes to Maximas so no way no how, I am going to do it myself. I will order the parts from a dealership in the US or from a Junck yard in the US because I don't even trust the Mexican dealerships here in Mexico. I would not be surprice if I buy the part here and get a made in china part insted. (picture that I asked for Nissan Matic D and they told me that they never used it, lol-no wonder why all Maxima Infiniti transmissions here are broken)
So it was a Used Ecm. I understand it may have been running, do you know if it's the correct part number? Also it may have a issue already with the Ecm which may be the reason your still having issues. Was the IAC from the dealer or your local auto parts store?
my friend has a 2002 sentra 1.8 and has a #1 misfire, and the idle surges when the rpm is help at around 2k. misfire is bad at idle and almost gets better as engine speed rises. the plugs where destroyed when i first got it (autolite junk). put new plugs and swapped coil around then his dealer rec new injector and we put one in and still nothing. i read the computers go bad and some have recall. is ther anyway to kno forshur before i call it a computer. any test
Great video this is the problem I have with my 01 maxima , will another ecu from another car it's an infinity like the one you working on , will it work on my maxima ? would it be possible to program my key to it ? Also do I have to replace both iacv and ecu at the same time
Hard for me to say with out seeing the condition of the car. But if that is the only issue with the car, I don't see a reason why you would need to sell it.
Sorry Eddie, the only way to program keys is with a scanner. There is no tricks to programming keys. If you can not afford the scanner which most people can't, then it will need to be done for you, or see if you can get a mobile locksmith to program it for you.
So I’m having trouble with mine I took it to a mechanic shop bought a brand new ecm and for some reason they locked my car so now my security light is on do u know how to take it off or fix that issue
Hi, need your help. I have had problems with cold start and some idling issues. I have 0505 code now. I went to mechanic and he said idle control valve is damaged. He replaced it and the car improved. every now and then I can stiff feel rough idle. does it mean my ECM is damaged?
If the Ecm was not repaired along with replacing the IAC, then you will continue to have issues. Both have to be done at the same time, other wise you will continue to have issues.
Nice videos. I had a question. I have a 2000 I30 that was running just fine. Recently the car has started to shut off just randomly. If you wait around 10 minutes it will startup and drive on like nothing happened. It seams to run only for around 10 mins or so and will do it again. The check engine light came on and the code that was set is P0505. I reset the code and just let the car run for 5 mins or so in the driveway the code did not come back so far. If it was the IAC would it immediately reset the code?
I have seen online where some say you need to replace the engine mounts is that correct? Thank your video has helped a lot almost have got it back together
what kind of scanner you using cause I need one to program keys and relearn idle in 01 maxima let me know do all scanners have this fuction or just this one how much is it and the name brand modle thankx
If you have a P0505 code, replace both.. Don't take any chances. Not all Ecm's are as burnt as the one in the video. Replace them both at the same time. Do it once and do it right!
If you watch my video's, the first thing I do is the Key programming so I can get the vehicle started. Once started, I allow it to get up to operating temperature and then I perform a Idle Relearn to verify the repair.
It say iac busy, then it say can't communicate. I'm using obd2 bluetooth with nissan lite program which has idle relearn. Just got the car it seems the iac is new,but get po505 , the idle is 1100 . Car turn on stays on no problem other than idle high.
Great video!!! I have a question. I have changed my IAC, MAF sensor and my ECM. Went to nissan to have my keys reprogram. Nissan also did a ECM relearn. Is that the same as a Idle relearn? I am still getting the PO505 code. Any Ideas? thanks

great videos brother.you helped me out a lot thank you very much and God bless you.😊
the ECM came from a maxima that had 80k miles on it. my car has over 300k on it. i really dont want to spend 2 to 3 thousand dollars for a new ECM

can you drive the car to the dealer even though you never did the relearn it yet for them to relearn the idle?
96, I don't think you need to program the keys. So if your looking to replace the Ecm, it's just a matter of removing and installing.
Thanks for the video, Wondering, What scan tool are you using ?
Thanks for that dude. you probably a nissan technician to have this computer! it really helps haha
Hey there i know how to turn a wrench it looks fairly easy to do. I dont have a relearn machine. If i replace the ecm as well as the IAC can i drive it to the dealership for a relearn or will that blow the ecm again. Trying to be as careful as possible
Chris Dell , did you ever replace both?
And if you did, was it okay to drive it
to the dealer like that without getting
blown again?
Your welcome! That is a Nissan Scan tools called Consult.2
You could, but the tools are like 6k bucks to program keys. One kit is called HOTWIRE, if you don't get a Nissan Consult.
Ecm is under the drivers side of the dash, and will require a scanner like the one used in this video to program the keys.
is there anyway of reprogramming the key other than the dealership?
YEP
Once this IAC and ECM is repaired, how can it be prevented from happening again?
EXACTLY! On a 2001 nissan maxima auto i have a IACV taken apart right now and its full of radiator coolant in my intake and down to my air filter. Now with that said is this a defect of the old IAC leaking? and is this what burns it out?
That is the Nissan Scanner called Consult 2
Great video. My IAC went bad. Question, if i had the ecm repaired do i still have to get the keys reprogram? I see that relearn is a must.
I don't recommend repairing the Ecm, I have never seen them work right after repaired and can put you back at square one. But if you do want to try to send it out for repair, that is up to you.

That is a risk of damaging the new IAC. But if that old one was bad, then it's very likely the Ecm was affected by it.
FixyourNissan 10-4. What’s the best way to verify? Pull ECM and look for the burnt chip?
You can certainly do that. I would also smell the connector as well to see if it smells burn
I took the IAC housing off the throttle body and didn’t find any coolant in the IAC ports, gasket still looks good. Connector didn’t look damaged but I didn’t think to smell it. I’m gonna do a coolant bypass and hope for the best. Thanks for your help
Yes, the Relearn is most likely the Idle Relearn. If your still getting the P0505, then there is a good chance the Idle Relearn didn't complete. If you care to speak to me more about this, go to JustAnswer and ask for Jay.
About how much will this repair cost at the dealership have any idea also great videos really helped
The Ecm New from the dealer & the IAC new from the dealer is around 1k bucks. Labor is 4 hours. So around 1400 to repair this.
FixyourNissan that is what i thought 👌
Yeah, it's Reman from the dealer. They work fine. It's the repaired ones that never work, that is what you have to watch out for!
You should be fine with a Ecm from Courtesy Nissan!

you rock dude your so intelligent

Yes, but if you replaced the Ecm with the IAC, how are you going to drive the car if you need the keys programmed?

The check engine light came on and the code that was set is P0505. I reset the code and just let the car run for 5 mins or so in the driveway the code did not come back so far. If it was the IAC would it immediately reset the code?
Mass air senser is going bad .... Replaced minds no more problems it read that code when the senser going bad
The ECM came from a running Maxima. the IAC came from nissan.
I have seen online where some say you need to replace the engine mounts is that correct? Thank your video has helped a lot almost have got it back together
The engine mounts can also burn out the Ecm. I recommend to simply unplug them. This way they can't harm the Ecm
+FixyourNissan so leave them unplugged for good
thanks for your video was very helpful
what kind of scanner you using cause I need one to program keys and relearn idle in 01 maxima let me know do all scanners have this fuction or just this one how much is it and the name brand modle thankx
did you find out what scanner to use?
yes it is the correct part number
If you have a P0505 code, replace both.. Don't take any chances. Not all Ecm's are as burnt as the one in the video. Replace them both at the same time. Do it once and do it right!
What can of scanner are you using
Is there a manual way to program the key or does it require a certain scanner?
+victor mcintyre Has to be done with a scanner
+FixyourNissan thanks! Looks like I'll have to take it to the dealer or find someone with a scanner
It has to be done with a scanner I am afraid. Either done by the dealer or a Mobile Locksmith.
okay.i get this done...is the car a keeper??? or,get it to a sell it off....137k
who do u pay to do a relearn the dealer or can a mechanic do it.
should i try to use one out of a used maxima to replace?
If you get one from a junk yard or used one, that is most likely the reason the car is not on the road.
what is the name of scanner are you using on it ?
That is the old style scanner. It's call Consult 2
how did u go upon buying your parts
I gotta new ecm and my car only cranks... does that mean I got the right one?
Did you program the key after you replaced the Ecm?
FixyourNissan no I just connected the Ecm and that was it....
So I gotta get the keyed program?
And what eles?
If you watch my video's, the first thing I do is the Key programming so I can get the vehicle started. Once started, I allow it to get up to operating temperature and then I perform a Idle Relearn to verify the repair.
I need mines done how much and what city u r from help please
I am in PA
I live way in hartford Connecticut
Hom much are those scanners?
They don't make them any more. If you find one, its around 2600 or so.
scanner can't communicate with iac to run relearn ?
What do you mean it can't communicate?
It say iac busy, then it say can't communicate. I'm using obd2 bluetooth with nissan lite program which has idle relearn. Just got the car it seems the iac is new,but get po505 , the idle is 1100 . Car turn on stays on no problem other than idle high.
Did you replace the IAC and Ecm both at the same time?
I recently purchased the car but seems the iac is new . I guess I'll see if the ecm has anything burnt. Will the car still run fine with a burnt chip?
Bad Ecm then if all fuses are good.

Great video!!! I have a question. I have changed my IAC, MAF sensor and my ECM. Went to nissan to have my keys reprogram. Nissan also did a ECM relearn. Is that the same as a Idle relearn? I am still getting the PO505 code. Any Ideas? thanks
