Does anyone know the ECU pinout diagram of a Nissan Sentra super saloon AT and its expected voltage?

Hi,

I'm not familiar with a Super Saloon. When I checked on a 1996, I was only provided with one option in two different manuals, so I'm not sure if you are located in the US or not and have something different.

Take a look at what I attached. It is for 1996 Sentra L4-1597cc 1.6L DOHC MFI (GA16DE) It includes ECM information for either an automatic or manual transmission.

Take a look through the pics and let me know if they help.

Take care,

Joe

I have a 64-pin label 8Q mec-N103 that has blown out then and I purchased a replacement with labeled mec-n105. I need some wiring diagram of this ECU to diagnose some voltage output and input in my ECU.

Hi,

The one I provided is the only thing in my manual. Is this a traditional Sentra as I identified above? I just went through all the powertrain management schematics. At the ECM, there is nothing that indicates a different connector.

Could you upload a few pics for me to see what you are working with? I even tried finding the part using the part numbers you mentioned without success.

Let me know.

I wonder if both of these ECUs have the same ECU pinout diagram as they have the same ECU connector. Both ECUs were from a Nissan super saloon 95or 96 model and b14.

Hi,

It is possible the pinout would be the same. I just don't have a way to confirm it. Have you tried the replacement part? If you have, how did it respond?

Hi,

Are there any indicators of problems such as a check engine light staying on while the engine is running?

Let me know.
