Crazy issue...TCS and ABS lights on...stumbling and climate control won't work

[M-P]

So I have had some gremlins off and on now for a while. It started with my ABS and TCS lights illuminating and the car goes into a kinda limp mode. It only did this every few times I would start the car and would only last about 30 seconds. I checked the codes and got ABS #49, which is "all speed sensors."

A couple of weeks later it did it again, except this time it wouldn't leave limp mode. I figured, lets see what happens when I remove the abs fuse. Fuse removed and everything works again. Then I didn't drive the car for almost 2 months because my inspection lapsed and I was too busy to get that done.

I finally got the inspection done and have been driving the car the past month. A couple of weeks ago, even with the ABS fuse removed, I started getting the limp mode problem again, except this time whenever it would happen the climate control simply wouldn't turn on. Then all of a sudden, the car would stop limping and the climate control would come back on.

I posted a thread earlier with no responses and have tried searching, but I can't seem to find anything that is similar. Anyone have any ideas?

Sounds like a bad ground connection, somewhere.

Bad ground, loose connector, mouse chew, flaky ECU, etc. Put the fuse back in, clear the codes and retry. Wheel speed sensors are a known problem on the NSX. You may have multiple problems. At least make sure the main ground connections (battery and engine to frame) are clean and tight.
Good Luck!

Ignition switch or mail relay are high on the list things that get intermittent and cause weird issues. As for the climate control they all fail at some point so yours is most likely at that point.
