Hi,

I have to replace ECU on my Nissan Sentra 2001 that has the same dealer part # 23710-5M110 , box# JA56Q21B58. Did you have any luck finding out if there is any interchangable ECU with different part #?

Thank you,

When you open the hood, it is on the passenger side, right in the top corner. There are a couple of screws that you first have to remove.

if it's right hand drive i wonder if it would still be on the same side? here, i did this for a guy the other day, this is where the ecu is located on my 01

how did you know your ECU is brocken? (just wondering if its the same with mine) my car is idling strange, up and down 1200rpm-1500rpm-1200rpm-1500rpm continously, they scanned it and they changed throttle plus idle control unit,(which i paid for it)nothing happens,and then diagnosed as broken ecu. is it the same with you?

i got a question, in replacing ECU.. Unplug the broken ECU and plug the new one and thats it? do we need to do something else? thanks!

**b15chik** · Jan 16th, 2008, 11:38 PM

it depends on if the new ecu has the same options that are on your car and a few other things. just plug it in and see if it starts

if not, come back, lol

The Sentra ECU's that are housed in the black box are not just ECUs, but
PCM's (powertrain control module). In other words, they are both an engine and transmission
control module in one.
Later models they reverted back to the two seperate control modules.
Anywho, there are varying symptoms of this, from trouble codes stuck, oxygen sensor heater
problems, idling problems, misfires, no injector signals, no AC clutch activation, and no start to
name a few.
So to make a long story short, b15chik is right. Unfortunately, most cases the problems that arise are
misleading and usually the tech only has the option of trying a known good PCM to see if the problems
go away.

You should be looking for a dealer code that starts with 23710- or similar, not the one writen on the box. The best way to find the actual code is to call a dealer service and give them the VIN number and they will tell you the right number. A very good site through which to find used ECM-s is Car-Part.com--Used Auto Parts Market. That's how I found mine. I
