I put a extra tranny cooler n changed the fluid and knock on wood but hasn’t happened since about 15k it’s been I’m at 144k now on my 11’ max I even get a lil better gas mileage. I too went down that rabbit hole n changed crankshaft, camshaft, position sensors also speed sensor, and did a re-learn n not till fluid change and extra tranny cooler did it stop.best of luck I know how big pain it is and dangerous it is

Well so far it’s been fine knock on wood, every piece of wood! I cleaned the grounds and did relearn on my own and it hasn’t done it again since

Also, I contacted the dealer and they weren’t interested in hearing about the relearn TSB, they said that’s what the mechanics use as references and not the same as a recall so they wanted $100 to do the relearns. I told myself I would have them do it if the problem came back and so far it hasn’t so I saved $100 so far

It’s back... this morning getting off the freeway I stopped at the light made my turn and the dash lit up and went into limp mode. When I got home I didn’t turn the car off and scanned it and it came up with p2135 throttle position sensor. Anyone have any advice?
i just want this fixed and not keep coming back. It’s been several months since I cleaned the grounds, replaced throttle body and gas pedal and did the relearn myself.
Anyone else have this happen? What fixed it?

So the dealership called and said it’s the throttle body, which i replaced with a hitachi throttle body from rock auto about 6 months ago...but when I replaced the throttle body it did not resolve the issue...it was when I cleaned the grounds and did the relearn that it stopped going into limp mode until last Friday...

im currently having the same issue and the dealer won’t diagnose it because of the after market parts but did you ever find out what the issue was and how did you fix it

So I downloaded the service manual and went through all the troubleshooting steps for the codes I had. Which was basically checking continuity between the connector at the throttle body and the ecu, then checking to make sure both spots are receiving the proper information from the pedal. All of this testing came back fine. I ended up putting the stock throttle body back in for ****s and giggles, did the relearn again and it hasn’t gone into limp mode for almost 2,500 miles.

I wish i had an actual resolution for you but I haven’t been able to find a definitive problem. So at this current point all I’ve really done is replace the pedal with an oem one from Nissan but initially that didn’t resolve the problem.

If capable, you should get the service manual online and look up your code and go through the diagnostics/trouble shooting steps yourself just to rule out there being a wiring/connector issue.

Just do a google search or search in the forums, it’s everywhere
