These codes could be a magnitude of things, what is the car? Year? Mileage? Trim? Any symptoms or issues? Service engine soon light on?
Details needed for guidance.

 

Google has those codes. Can bus connectivity was one of them. Like Mahandeem asked what are the details?

 

2010 nissan maxima s with 107 on dash I got it at 23 the check engine light comes on and off

 

I get P0725 and U1000 when every I re-flash my ECU with the UpRev ROM editor. I have no drive-ability issues and I don't actually get a light. If I clear it, it won't comeback until I reflash. For the heck of it (and what I would suggest) is to check your grounds. I did clean mine up on some spots (battery to Transmission) and added extra grounding, though I don't think this had much impact..

 

How does UpRev serving you? Does it really "tweak" performance?

 

I replaced the positive terminal and clean the negative terminal and turn on the car and everything was going no check engine light do you guys think will it come back it says online it's a speed sensor and what is a UpRev ROM editor

 

My bet is ground or power issue. Was it driving poorly?

 

To be honest it's been sitting in the garage for almost 2 months that I took it out did a oil change and everything else to it butt. Positive terminal was corroded in my fuses was gone so I replaced everything today when I turned it on the engine light was still on drove it for a little bit just got in a right now and it's actually off but overall the car is running good

 

Clear codes, drive, and enjoy.
If same codes come back soon, then have a deeper look (provided car is running fine and you have no drivability issues).
That's pretty much what I do with almost any CEL problem.

 

Hey I went to nissan dealer and hold them about the check engine light that come on and off and they told me I have to get the computer update I never heard that before is that true I can do a computer update its about 150 they told me

 

Probably they relate the U1000 code to faulty module communication. I'd do the ECU update, might not fix things but I don't see it cause additional problems, and if I remember correctly update also tweaks CVT RPM-shift points for 09 and 10 so if 150 is swallowable for you do it but let them know if you still get CEL they need to continue to troubleshoot things.
