are all codes the same for nissans?

[Chris111]

My car has a hesitation and I checked the ecu and it was a 55. My friend looked it up in a 200sx se-r book and it said that it's the EFI and it says next to it that there are no problems detected. What does that mean? I'm asking if they are all the same for all of the nissan ecu's, like honda's have the same codes for every ecu. Someone said before that it could be the timing and I checked that and it was perfect. Thanks for the help.

yes all codes are the same.up untill 96, then all car mufacturers were required to have the basic codes be the same for all cars.

Thats good to hear, now i just need to find out what the deal is with the EFI code. It doesn't make any sense.

55 means nothing is wrong. there are no fault codes stored.
