Thank you for this video, about to buy an ECM to swap for my Spec-V. Was wary about having it reprogrammed, my 5v reference is shot on my ECM. This gives me confidence in being able to swap out the ECM for the SE-R. I LOVE the Sentra, had it about 10 years now but got a P0320 code and no 5V reference, ran rough at idle, shut off erratically while driving, now no spark as a result of no reference signal. Hopefully this does the trick, inspection is due soon. :S
Thanks, replaced my ECM , seems to have solved the problem. Check engine light went off, car no longer stalls and starts right up. - it also got my cruise control working again.
thanks for this video, i've been going crazy trying to figure out why my car keeps cutting off and wont start. after letting sit for an undetermind amout of time it starts up again. Im going to make some phone calls and try and find another ECU and see if that works. Thanks Again For Sharing This Video.
Its so funny all the problems you mention in this video, I have experienced problems with the parts mentioned in some way with 3 of these cars I have had. Can't pull codes from my 02, all 3 had coil pack problems, both 03s had bad fuel pumps (i know in his case it was the ecm) and both 03s shut off while driving. Those ended up being the crankshaft sensor though, not super fun to replace. The electronics on these engines just really suck. Right now my car fails when its very warm, can't accelerate and the car dies. Then I jump it and it kinda works fine then the next day works fine for a long time. Then fails and won't start
Hey thank you for making this video and sharing your experience. I have a 2002 sentra ser and I keep getting the P0031 code for low voltage to the heater circuit in the upstream o2 sensor. Apparently the ECU's for these car's are not very good but the 2004 ECU is one of the best out there is what I'm told from an ECU repair place. I'm going to take the ECU that is in my car and send it to them to repair and I hope that will the be the end of it but I will let you know how that goes as well. For the repair it is only $120 or so and it also comes with a lifetime warranty.
I had the same problem , we couldn't fix the orifginal ECU what we have donne is that we made an adaptation of a Peugeot 1.8 gasoline ECU and we changed also the throttle body ass well , now it is working perfect
the ecm is easy to swap out. the problem I was having the scanner would not communicate with ecm. If you are able to connect and read codes the ecm might not be your problem. also check and clean all body grounds for corrosion there are over 10 ground connections
Would you mind telling me how? I still have this kind of car and know nothing. I’m trying my best to get it back working. Got it narrowed down to something with the wiring. And I read on a forum that it had to do with the ground connection but I’m still pretty lost.
@@bgower86 there are grounds all over the engine compartment about 8-10 grounds including 2 on the back of the intake manifold. I suggest taking them off one at a time cleaning off the rust then reconnecting.
Thanks so much bro for the video i thi k my car has the same problem but its only shut off when its parked after i drive it and sometimes won't start imma try jt thx tho
I was hoping it wouldn't be the ECU on the 02 Sentra 1.8 4cyl same stall at 55-60 mph 300.000 miles though I disconnected the evap solenoid thought it might help don't know yet
My scion xA had the same problem. It shut off on the highway, when idling, or wouldn't start. I replaced coils, crankshaft sensors but problem persisted. I replaced ECM last week, so far it hasn't shut down. I hope that was the issue.
Question pls. I have 2002 sentra 2.5 ser automatic with security system. My ecu is bad , so I need to replace It. How do u go about getting another one. U do see them on ebay but I'm not shure what numbers to look for. There are some number on the top and big K4 in the middle and other number at the bottom. Any help will be so helpful please
@@bigben4159 Same. There could also be a crankshaft censor issue. That was what was wrong with mine. They have to reprogram the matching ecu to find anything wrong.
2004 Nissan Sentra I can retrieve trouble codes from the ECM.. but you mentioned something about checking all the grounds for corrosion and you said there's about 10 of them.. do you know where all those grounds are located
Question? Does the last 4 digit has to match the old to the new ecm computer. Because my ecm is G6 mec 33 292 A1 3713 and the one I found online is G6 mec 33 292 A1 3803. The last number still has to match?
I have the exact car mines a 2001 but same issuecranks but wont start. I put a new alternator in it a new fuel pump got a new battery the new coil I change the crankshaft sensor. But I hooked my little Doohickey thing to it and it saidfuel intermittent circuit A something. End it also says not communicating with the vehicle or something like that. Sorry for the punctuation
I'm having the exact same problem with my 2002 Nissan sentra se-r. The machine won't connect and read codes. Figured it had to have been my ECM since my car just shut off on me and wouldn't start back up. But...I've heard you have to take it to a dealership so they can reprogram the replacement ECM. Did you bypass that and your car worked? If that's the case, how so??
I'm having a problem with my Nissan Sentra #2001.i got the engine pressure washed.and all of a sudeen I was driving and car did I changed the coils but only one of them gets spark.the coils are good I tried them before buying them, could this be a bad ecu? Any help is good.thanks
Bro I need help from Bangladesh, my car is Nissan Sunny X Saloon 2002 model, the car starts after some places, then it stops suddenly, it starts again, after giving a lot of help, it cranks and does not start, after taking a rest for a while, it starts again. Turns on and off again, please tell me for which purse this happens.
Man i think my 2003 altima is doingthe same thing..random stalling ..im thinking its either the coils or its the exu cuz i checked the voltage and ground on each coil pack connector voltage should be between 10-12 volts...now only thing is ubcant check the signal wire with a multimeter and if the car is not getting spark the connectors have voltage and if you just put in new coils..chances are is its a bad ignition relay or or ecm or pcm is not sending a signal to the coil packs..if so time to replace..all though i did get a multiple misfire code so theres a very good chance its bad coils..but we will see hope its not the ecm
I bought 2002 Sentra GXE from auction for 16 years old daughter and it wouldn't start. P0600 and p0335. I ordered new crankshaft and camshaft position sensor. New coils and plugs. I sent ECU to get repairs. They called yesterday and said it's working properly. They saw the codes and reflashed it. They said the p0600 is a wire correded or broken. Where should I begin to look? I also took battery to get recharged. I noticed in video there is yellow by ECU housing around some wires. Can you please send me pictures of where to look? Thanks brother 😁
my sentra had no comunication with scanner meaning no codes at all. there are ground wires all around the engine compartment remove and clean them all for corosion especialy the ones by battery box and ground wires attached to intake manifold
I'm thinking about buying an 02 sentra se-r spec v which needs a computer and battery. He's asking $1,200 obo. Do you think it's worth it? I used to own an 04 same model and i loved that car.
My Sentra is doing the same thing at times it shuts off or attempts to shut off, has check engine light on and every time I scan it it says error could I be having the same problem?
What was the mileage on your car? I have a 2007 Sentra with 305K km on it, it will not start. It would shut off at a sudden stop, but now it does not start up. Could it be the fuel pump, how to I check the voltage at the fuel pump to make sure it is faulty?
Since your question did not get answered I will answer it for you, The ECM has to always get Programmed before installing or else you will run into some more problems and the part where you scan it is on the drivers side underneath the dashboard area, kind of by where the pedals are , if you kneel down and look up you’ll see it
Bro I don't know you but thanks so much for this help you help me to save a lot of money I do appreciate it keep doing this

hey man i got the same code was it the throttle control circuit was you able to fix it
Thanks, replaced my ECM , seems to have solved the problem. Check engine light went off, car no longer stalls and starts right up. - it also got my cruise control working again.
Whats up..what numbers needed to match. As i need a ecu as well.

That sounds like a great deal. My 04 ser never had any electrical problems.
the donor ECU did not need to be reprogrammed. I just used a regular OBD II scanner plugged into the port under dash
THANK YOU SO MUCH
when you put the ECU in, you didn't have to reprogram it? or calibrate it?
Thank you !!!! Will try it. Will let you know later. ^_^

work..

Buen video
Thanks for the video! One question when you were having the issues were was anything electrical working Inside the car? Lights or gauges?
My windows don’t roll up or nothing

It. How do u go about getting another one. U do see them on ebay but I'm not shure what numbers to look for. There are some number on the top and big K4 in the middle and other number at the bottom. Any help will be so helpful please
thank you
No i did not have to reprogram it the part number matched my old ecu
Did the last 4 digits match?
I got a used one exactly same numbers and car does nothing
@@bigben4159 Same. There could also be a crankshaft censor issue. That was what was wrong with mine. They have to reprogram the matching ecu to find anything wrong.

Does the last four digits have to match? Like the mec 63 300 b1 matches but different last numbers.
Question? Does the last 4 digit has to match the old to the new ecm computer. Because my ecm is G6 mec 33 292 A1 3713 and the one I found online is G6 mec 33 292 A1 3803. The last number still has to match?
all other electrical such as lights, gauges was working ok only engine affected by ecu
Do u think that the ecm would be the problem in my case since the car tugs and pulls I've changed all sorts of stuff and still the same.
I have the exact car mines a 2001 but same issuecranks but wont start. I put a new alternator in it a new fuel pump got a new battery the new coil I change the crankshaft sensor.

Yep feul pump worked on mine coil packs fine but the computer wouldn't let the enjectors work.

i just found an ecm with the same part # it was out of the same type of sentra and it worked no dealer reprogram needed
You're a Godsend, man, thank you!
Did you have to get the ECU programmed? I heard that you don’t have to get it programmed. Trying to make sure. Help!!
Congrats on that! is it ecm or ecu?
I'm having a problem with my Nissan Sentra #2001.i got the engine pressure washed.and all of a sudeen I was driving and car did I changed the coils but only one of them gets spark.the coils are good I tried them before buying them, could this be a bad ecu? Any help is good.thanks
no the ecu I got did not have to be programmed. make sure the numbers match the 4u and numbers on top
Does the serial matter or is jsut the top numbers and the letters
Did your car have a emmoblizer (as many of your model did ) , if so you would have to reprogramme it and also your keys otherwise your lucky
Where i can buy brand new ecu or ecm for my nissan sentra bro

$1200 not a bad price if that's all it needs. it has the 2.5 engine that had other problems like the catalytic converter issues. they are fun to drive
I think last 4 digits are the serial #. as long as all other numbers match it should work., not 100% sure
nightwrencher nj
nightwrencher nj thank you 2001 Nissan Sentra gxe 1.8 with problems with ECM going to replace now!
Mine is just revving throw the roof. It's the world's first stock drag Sentra
I know this is 5 years old ... but can you send me the link to the ebayer ????? Thanks
did you have to get the ecm flashed?
Where exactly did you buy the computer?
can you please tell me where the egr is? thank you
dangerous stuff
I found the replacement ECU on EBAY
My Sentra is doing the same thing at times it shuts off or attempts to shut off, has check engine light on and every time I scan it it says error could I be having the same problem?
You ever figure that out? Same problem here
I'm having trouble with my sentra ser 2003 it won't start cranks but won't start does anyone know how to solve this problem
What was the mileage on your car? I have a 2007 Sentra with 305K km on it, it will not start. It would shut off at a sudden stop, but now it does not start up. Could it be the fuel pump, how to I check the voltage at the fuel pump to make sure it is faulty?
gotta pop the back seat out and remove the cover protecting the pump.
it's happening to me now thank you tomorrow I'm going to the junkyard to get the ecm for my sentra and it's a 2000 model are these cars defective??
Yes they are definitely.
thanks
I need thz number of fan belt

hi did you have to get donar ecu re programmed? also where do you plug in scanner
Since your question did not get answered I will answer it for you, The ECM has to always get Programmed before installing or else you will run into some more problems and the part where you scan it is on the drivers side underneath the dashboard area, kind of by where the pedals are , if you kneel down and look up you’ll see it
